We're opening Arcade21 to a select group of founding testers. Drop your email — we'll reach out when your spot opens.
An ecosystem of P2P games is growing on Chia. Ship yours with the Chia Gaming SDK — state channels, stake escrow, and a live player base from day one.
Peer-to-peer skill matches settled on the Chia blockchain. Zero rake. Provably fair. No middleman.
Peer-to-peer skill games on Arcade21 — every match player-vs-player, every result settled on-chain. Find your table.
Filter by genre, players, stake, status. Sort however you want.
Real-time peer-to-peer sessions — stakes settled on-chain, zero platform rake.
Find a room. Join the match. Win XCH.
/announce on this deployment.Premium advertising slots on the Arcade21 home page. Direct sales, no networks, no auction floors. Every visitor sees your ad in our Network Pulse panel — the busiest real-estate on the site.
Additional slots (Lobby sidebar, Chat banner, Game Store) opening soon — apply below to be notified.
Every ad is reviewed by an Arcade21 admin before going live. We may decline any submission at our discretion. Approval typically takes 1–2 business days.
Real-time status of the Arcade21 Game Tracker infrastructure, connected games, and active rooms.
Global standings across every Chia peer-to-peer game. Ranked by wins, win rate, and XCH staked. Every match is provably fair — every result recorded on-chain.
A Chia game can settle a real-money match in seconds without a server, a payment processor, or a casino license. Open SDK, live player base, zero infrastructure to run. Ship the next great game on Arcade21.
Skill duels. Strategy boards. Word puzzles. Social party games. The Chia gaming protocol gives you cryptographic primitives that work for all of them — match logic in your code, settlement on-chain.
Spend your time on game design and game feel — not on payment infrastructure, KYC pipes, anti-cheat heuristics, or matchmaking servers. The protocol does that work.
From a sketch on a napkin to a real-money match between two players — measured in days, not months.
Most chains weren't built for gaming. Their consensus mechanisms are too slow, too expensive, or too centralized for real-time peer-to-peer gameplay. They can hold assets, but they can't settle the microsecond logic of a poker hand without making every transaction cost more than the stakes.
The hard problems are solved. State channels work. CHIALISP® works. The player base is on the platform. The only thing missing is your idea.
Every game on Arcade21 is one-on-one through a Chia state channel. That looks like a constraint until you realize it makes tournaments simpler, faster, and provably fair. No tables of eight. No house. No custodian holding the pot. Every bracket round is a state-channel match. Every settlement hits the chain.
State channels are the right primitive for trustless gaming. Tournaments are the right primitive for finding out who is actually best. Arcade21 is the first place both work together at real stakes.
Every tournament pool is a chialisp coin. The bracket contract is the only signer that can release it, and only when the final match settles on-chain. Arcade21 holds nothing.
Chia projects, game developers, and brands can seed a prize pool directly into the bracket contract. Players get bigger pots. Sponsors get exposure to a captive crypto-native audience.
A single tournament spans Cal Poker, Battleship, Wordlock, and the rest. Points accumulate across games. The top earners advance to the championship round.
Anyone can add XCH to a tournament pool coin. The chialisp contract enforces that boosted funds go to the bracket winner. Spectators have skin in the game.
Weekly brackets feed monthly leagues feed quarterly invitationals. ELO and tournament earnings travel across seasons. Reputation compounds.
Tournaments only open to founding members. Smaller pots, exclusive bracket access, permanent badge on the leaderboard. One priority slot per founder per quarter.
The chialisp tournament contract is the only authority on the prize pool. It watches the chain for state-channel settlements in the bracket, advances winners automatically, and pays out when the final match resolves.
If Arcade21 disappeared mid-tournament, every player could still claim their share of the pool from the chialisp contract on-chain. The platform is the discovery layer. The contract is the bank.
Each format is built for a different player. Pick the cadence that fits how you actually play.
Classic format. 16, 32, 64, 128, or 256 players. Lose once and you are out. Final survivor takes the pool.
Skill-paired matchups over N rounds. Everyone plays the full schedule. Better skill ranking than single-elim. The format chess uses.
A single tournament spans Cal Poker, Battleship, Wordlock, and more. Points accumulate. Top earners advance to a championship round.
Permanent ongoing structure. Climb the rankings by beating players above you. Top of the ladder collects a recurring pool from challenger fees.
A brand or game developer seeds the prize pool. Entry is free or low-cost. Players compete for the sponsored pot. Sponsors get exposure to the platform.
Where we are. Where we are headed. Honest targets; we ship when ready, not when convenient.
Eight games live on Arcade21. Channel-open and settle in chialisp. Shipped.
Real-time room discovery, ELO that travels across games, public leaderboards. Shipped.
Single-elimination bracket contract. 16 and 32 player events. Entry-fee prize pools. First open registration.
External funding flows directly into the pool coin. Swiss format for larger fields. Founding-member-exclusive brackets.
Multi-game point series. Spectators can boost any active pool. End-of-quarter championship invitationals.
King-of-the-hill structures. Any game developer can run their own brackets on the platform.
First brackets open in Q3 2026. The waitlist is open now and founding members get priority registration for every launch event. Subscribe for updates and we will reach out when registration opens.
The pot is pooled across the whole tournament, not per match. A 64-player single-elim has 63 matches and the entire entry-fee pool goes to the winner (or top three split, depending on format). Sponsored tournaments add external funding on top of entry fees, pushing pools well past what a single match would ever produce.
Yes. The pool is a single chialisp coin co-controlled by the bracket contract. Arcade21 is not a signer. The contract releases the pool only when the final on-chain match settlement is observed. If we shut down mid-tournament, players can claim their share directly from the chain.
Yes. The tournament infrastructure is exposed through an open API. A developer can fund a prize pool, set the bracket parameters, and run an event for their own game. Arcade21 handles bracket progression and on-chain settlement.
Yes. Sponsored opens with free entry and real prizes are part of the launch plan. Pro tier members get extra slots in free-entry events. Founding members get priority registration across the board.
By ELO when stakes are meaningful, so top players do not meet in round one. Random for casual events and free opens. Open brackets with no skill gate are available for players who want to start fresh.
Arcade21 is a recipient of the Chia Cultivation Grant. Awarded on March 25, 2026 on the merits of our team, product, and vision for contributing peer-to-peer gaming infrastructure to the Chia ecosystem. What follows is the public, milestone-by-milestone path.
Most roadmaps are aspirational. This one is contractual. Every milestone below was negotiated, signed, and committed to in writing. Each one carries acceptance criteria, a delivery date, and a non-dilutive cultivation tranche. We share it publicly because we think the work is more interesting when you can watch it happen.
Arcade21 is built on the Chia gaming framework, which Chia Network distributes under the Apache 2.0 license. Our application code, our tracker, our content, and our brand are ours. The underlying state-channel primitives are Chia's. Together they make trustless one-on-one gaming possible at consumer scale for the first time.
The foundation. State-channel gaming primitives shipped, five playable titles in the wild, and the onboarding flow that gets a brand-new player from zero to in-game in under five minutes.
The upgrade pass. The interface gets the finish it deserves. Players get real identities and progress they can show off. Five hundred beta testers are playing daily and telling us what to build next.
The release we have been pointing at since day one. State-channel-native tournaments with brackets, prize pools, and settlement nobody has to take on faith. Sponsors can fund the pot. Players play for free or near-free. The pot is held by chialisp, not by us.
Crypto-native is fine for the first wave. For the second wave we need to meet people where they are. Card in. XCH ready in wallet. Subscriptions for power users who play every day. The bridge between web2 wallet and web3 play, hidden behind a single button.
Most gaming is mobile gaming. So is most chia. Full mobile integration means the same matches, the same rooms, the same wallets, on the device you actually carry. The game library expands to match the form factor.
Aggressive user ramping. The content engine running at full speed. The TL;DR podcast hitting ten thousand listeners weekly. Code Cave webinars and daily X Spaces putting state-channel gaming in front of a much wider audience than it has ever had before.
A premium tier for serious players who want the deeper functionality. Developer tooling v1 ships. The GameTemplate toolkit makes it possible for a third-party dev to ship a new chia game in days, not months.
The arc completes. The platform is self-sustaining. The cultivation period closes with Arcade21 running at the scale we said it would, on the timeline we said it would, with the product surface we said it would have.
Every release ships from a public repo. Every milestone has acceptance criteria the public can verify. Every match settles on a public blockchain. The whole thing is supposed to be watchable. So watch it.
Chia Gaming is the open-source protocol that makes trustless peer-to-peer wagers possible without a casino, custodian, or per-move gas. Two wallets fund a shared channel coin. They play entirely off-chain. Only the open and the settle ever touch the blockchain.
Until now, betting online has always required trust in someone you can't see and don't know. Chia Gaming is the first protocol that removes the middleman entirely.
Casinos extract 5-15% rake on every pot. Sportsbooks build vig into every line. Web2 gambling is fundamentally a value-extraction service that runs on top of player money.
When you deposit on a gambling site, your money becomes the site's money on its books. Withdrawals can be delayed, frozen, KYC-gated, or simply refused. If the site dies, your balance dies with it.
Every shuffle, every roll, every "RNG" outcome runs inside a black box on the operator's servers. Players have no way to verify the deal was fair. Even "provably fair" implementations require trusting the operator's commitment scheme.
Chia Gaming is built on four core ideas, each of which solves one of the problems above. Together they make peer-to-peer gambling possible without any custodian at all.
A shared coin on-chain controlled by two players, locked behind a 2-of-2 multisig. Funds are committed when the channel opens, can only be released by mutual signature or via on-chain dispute, and stay locked until settlement.
Players take turns holding signing authority (the "potato"). Each pass carries an updated signed state with an incremented sequence number. Both players always hold the latest mutually-signed snapshot. Either can close the channel at any time to the latest state.
A chialisp puzzle that validates game moves on-chain when disputes happen. Each game ships with a chain of validator programs that verify move legality, compute state transitions, and slash cheaters. Provably correct, immutable, auditable.
The reference implementation. A poker variant using commit-reveal randomness so both players contribute to the deal and neither can cheat. Five on-chain validator steps enforce the protocol if the game ever hits the chain.
A complete Chia Gaming session touches the blockchain exactly twice: once to open, once to settle. Everything in between is between you and your opponent.
Most web3 gambling stacks claim "trustless" while quietly retaining custody, charging gas per move, or relying on oracles for randomness. Chia Gaming does none of those.
| Traditional online casino | Most web3 gambling L2s | Chia Gaming | |
|---|---|---|---|
| Rake on the pot | 5-15% | Variable, often hidden | Zero |
| Custody of funds | Operator holds everything | Bridge custody + smart contract | Player wallets, until settlement |
| Gas per move | None (operator pays) | Cents to dollars per move | Zero, all moves off-chain |
| Randomness source | Operator's black-box RNG | External oracle (chainlink, etc) | Commit-reveal between players |
| Outcome privacy | Private but operator sees all | Every move public on-chain | Off-chain; chain sees only final state |
| Smart contract risk | Operator software bugs | Upgradeable contracts, admin keys | Chialisp puzzles, immutable, auditable |
| Identity required | KYC + bank verification | Wallet + sometimes KYC | Wallet only |

Account, gameplay, payments, the Chia Gaming protocol, and the policies that hold it all together.
Arcade21 is a peer-to-peer gaming platform built on the Chia blockchain. Real-money wagers settle on-chain through state channels. There is no house holding the pot and no platform rake on winnings.
What you can do here:
Why it matters: Arcade21 is a passive directory. We don't custody funds or take rake from games. All stakes are peer-to-peer and settled on-chain by the Chia Gaming protocol.
Forever Free is the open-source default. You can play, earn, and settle every game on-chain at no cost to you. This is the experience for the vast majority of players.
Pro ($19.99/month) is for hosts and power users. You can host your own rooms, earn $Minutes at 1.5x, and unlock advanced profile features. See the Pricing page for the full comparison.
You can browse Arcade21 without a wallet. To actually play for stakes, you'll need a Chia wallet. We recommend Sage or Goby as both have first-class support for state-channel gaming.
Browser extension wallets unlock the smoothest experience. Mobile and native wallet support is on the roadmap.
Note: You can only join rooms if your wallet has enough XCH to cover the stake. Games are peer-to-peer and final. Make sure you understand the rules before joining.
Five games are playable today: California Poker, Krunk Words, Rock Paper Scissors, Connect 4, and Battleship. All five are state-channel native.
More are coming via the Chia Gaming protocol. See the roadmap for what's shipping next.
Tournaments are launching in October 2026 as part of milestone 3 of the cultivation roadmap. The format is state-channel-native: brackets, prize pools, and settlement that no central party controls. Sponsors can fund the pot directly into the bracket contract. Players play for free or near-free.
See the Tournaments page for the latest details and join the waitlist for early access.
State channels handle this gracefully. Either player can post the latest signed game state on-chain. The referee (a chialisp puzzle) reads the dispute, validates the move history, and settles the pot according to the rules. The disconnecting player loses if they were behind on signatures.
Practically: you'll see a timeout countdown when your opponent goes idle. If they don't return, the channel force-closes and you receive your fair share automatically.
No platform rake on the pot. Zero. The Arcade21 model is a directory + subscription, not a casino. The only deductions from a stake are the standard Chia network fees, which are typically a fraction of a cent.
This is fundamentally different from traditional online gambling sites that take 5-15% of every pot, or web3 gambling L2s that charge gas per move.
$Minutes is the platform's loyalty currency. You earn it by playing games and engaging with the platform. It accrues to your profile and is intended for unlocking platform perks (priority queueing, advanced features, future merch and collectibles).
Forever Free users earn $Minutes at the standard rate. Pro users earn at 1.5×.
Not yet. Fiat onramps are coming in January 2027 (milestone 4 of the cultivation roadmap). For now, you'll need XCH in your wallet to play for stakes. The easiest path today is to acquire XCH on a supported exchange and transfer to your Chia wallet.
Sage and Goby are first-class. Both are browser extensions that work in Chrome, Firefox, and most chromium-based browsers.
WalletConnect-based connections are also supported for desktop and mobile wallets that implement the standard. Full native mobile support is on the roadmap.
If you forgot your password, click Forgot password? on the login page. You'll get a reset link via email.
Email support and we'll process the deletion within 14 days. We delete your account record, profile data, and chat history. We retain a minimal anonymized record for fraud prevention and legal compliance (mostly: that an account with your email previously existed). On-chain settlement history can never be deleted because it lives on the Chia blockchain.
See our Privacy Policy for the full details.
Chia Gaming is the open-source protocol Arcade21 is built on. Two players fund a shared channel coin on the Chia blockchain, then play games entirely off-chain by exchanging signed messages. The blockchain is only used for opening, settling, or resolving disputes.
Read the Chia Gaming hub for a beginner-friendly walkthrough, or the protocol deep dive for the technical details.
A state channel is a shared on-chain coin that two players control together. They lock funds in it once, then sign messages back and forth representing game moves and the latest state. The blockchain only sees the final settlement.
This means you get the security of an on-chain settlement with the speed and cost of an instant message. Most games never touch the chain at all.
Three things make Chia uniquely suited to peer-to-peer gaming: Chialisp, the smart-contract language built around immutable, auditable puzzles; the coin set model, which makes 2-of-2 multisig channels first-class; and BLS signature aggregation, which makes the cryptographic dance underneath state channels efficient.
Ethereum-style smart contracts can simulate this, but at the cost of gas per move and upgradeable-contract risk. Bitcoin Lightning can't do general game state. Chia is the first chain where the protocol described above is genuinely cheap and clean.
Your XCH stays in your wallet under your private key control until you choose to fund a state channel. Once a channel is open, the funds are held in a 2-of-2 multisig coin that can only be released by mutual signature or via on-chain dispute. Arcade21 has no way to access your funds at any stage.
The biggest practical risks: losing your private key (back it up), getting phished into signing a malicious transaction (verify what you're signing), and the standard volatility risks of holding cryptocurrency.
Arcade21 is a passive directory of peer-to-peer games on the Chia blockchain. We don't custody funds, take rake, or host a casino. Players are responsible for understanding the gambling laws in their own jurisdiction.
The platform itself is in private closed beta. Public launch will include age verification, regional gating, and the standard guardrails for jurisdictions that require them.
Self-exclusion tooling is on the roadmap. In the meantime, you can email support to have your account temporarily suspended. We do not market to players who have asked us to stop.

Koba42 Corp, operating as Arcade21 ("we", "us", "our", "Company"), is a software company operating a membership-based gaming platform and protocol interface at arcade21.games ("Service"). Arcade21 provides software tools, a discovery layer, and membership benefits that allow users to connect with peer-to-peer games running on the Chia blockchain. The Service includes:
Arcade21 is a software service and membership company. We are not a financial institution, gambling operator, money transmitter, payment processor, escrow provider, or custodian of any kind.
This section represents a foundational operating principle of Arcade21:
Specifically:
For absolute clarity, the Service is not:
All games listed on the Service run entirely on the Chia blockchain through peer-to-peer state channels. Game logic, fund custody, move verification, and settlement occur exclusively on-chain between the players' wallets. Arcade21 is not a participant in, party to, or operator of any game or transaction.
You understand and acknowledge that:
Access: Platform access is currently invite-only (closed beta). You are responsible for maintaining the security of your credentials. Account sharing is prohibited.
Membership fees: Subscription payments are fees paid to Koba42 Corp for access to software features and membership benefits. They are not deposits, not wagers, and not held on your behalf. All payments are on-chain, final, and non-refundable once confirmed on the blockchain.
Subscription periods: Active for 30 days from payment confirmation. We reserve the right to modify tier features or pricing with 30 days' notice.
API keys: Issued to qualifying members for authorized programmatic access. Abuse, excessive load, scraping beyond stated rate limits, or redistribution may result in revocation without refund.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:
Platform rewards (XP, ELO, $Minutes): Arcade21 awards platform rewards — including experience points (XP), ELO ratings, and $Minutes tokens — based on completed game results reported through the Arcade21 game client software. These rewards are platform features, not financial instruments, prizes, or compensation of any kind.
Dual-report confirmation requirement: Platform rewards are only credited after both players independently report a matching game result through the game client. A single-player report places the result in a pending state — no rewards are awarded until the second player submits a matching report. This requirement exists to protect platform integrity and prevent fraudulent result submissions.
Disputed results: If the two players' reported results disagree on the winner, the result is automatically flagged as disputed. In a disputed result: (a) no platform rewards are awarded to either player; (b) the dispute is logged and reviewed by platform administrators; (c) Arcade21 reserves the right to determine the outcome of platform rewards at its sole discretion based on available evidence. Arcade21's determination of platform rewards in a dispute is final and not subject to appeal.
On-chain outcomes are separate: Platform rewards (XP, ELO, $Minutes) are entirely separate from on-chain XCH wager settlement, which is determined exclusively by Chialisp smart contracts on the Chia blockchain. Arcade21 has no ability to affect on-chain outcomes. A disputed platform result does not affect, reverse, or alter any on-chain wager settlement.
No guaranteed rewards: Platform rewards are offered at Arcade21's discretion and may be modified, adjusted, or discontinued at any time with reasonable notice. Past reward rates do not guarantee future reward rates.
By using the Service, you expressly acknowledge that:
Access to the Service is restricted to adults who meet the minimum legal age for online gaming and wagering in their jurisdiction. By using the Service you represent and warrant that:
Arcade21 conducts age verification by self-attestation, supported by jurisdiction detection (IP-based) and an audit log of every attestation. We reserve the right to require additional identity verification at any time, particularly in response to law-enforcement requests or where there is reason to suspect a misrepresentation of age. Providing false information about your age is a material breach of these Terms and grounds for immediate termination, forfeiture of platform rewards, and (where applicable) referral to law enforcement.
The Service is not available in all jurisdictions. We use IP-based geo-detection (via Cloudflare edge headers) to identify and block access from jurisdictions where the listing or facilitation of peer-to-peer real-money gaming carries elevated regulatory risk. Blocked regions currently include, without limitation:
You may not access or attempt to access the Service from a blocked jurisdiction, including by use of a VPN, proxy, Tor, or other circumvention technology. Doing so is a material breach of these Terms and may also violate applicable export-control or sanctions law. Even where the Service is technically reachable from your location, it remains your sole responsibility to determine whether your use of the Service is lawful in your jurisdiction; we make no representation that it is.
You may not use the Service to:
We reserve the right to suspend or terminate accounts in violation of these terms, at our sole discretion and without refund.
The Service's source code is published open source under the Apache License 2.0. Game titles, brands, and SDK components remain the property of their respective creators and developers.
