Paper beats rock.

A fantasy MMO where combat is a readable 2D board under your feet.

Gridcasting is the core loop. You choose a tetromino ability, preview it on the ground, place it, and watch the board react. Outside the grid, the world is full of civic repairs, permits, toys, and discoveries that get recorded and credited.

Overview

Ruboria is a systems-driven MMO. You solve problems by placing clear patterns, using tools, and letting the world rules do the work. It is designed for MMO veterans who like readable mechanics, clean feedback, and teamwork that feels practical.

Adventure pockets

The dangerous layer is built around localized encounters and puzzles. Your choices shape the board. The best wins look obvious after the fact, because the rules are consistent.

  • Pick a mino, aim, preview, place
  • Elements spread, combine, and convert
  • Tools and terrain matter as much as stats

Civic sanctuary

The civic layer is for repairs, routing, permits, and small contraptions that make towns feel alive. It is a safe place for maintenance loops, social hubs, and playful machinery.

  • Fix infrastructure and stabilize systems
  • Use stamps, tools, and civic gadgets
  • Turn chores into tiny puzzles

Discovery legacy

When players prove a repeatable maneuver, it can be recorded and taught. Discoveries can earn a permanent name in the world.

  • Find patterns through play
  • Teach discoveries in settlements
  • Build a history that sticks

How it plays

Gridcasting is a simple action loop with deep outcomes. You are not memorizing long rotations. You are setting up cause and effect.

1
Choose a mino ability. Each one has a clear tetromino footprint.
2
Aim at the ground and preview placement on a tile-aligned board.
3
Place the pattern. It applies actions and states across those tiles.
4
Read the reaction. Chain clean follow-ups instead of panic casting.

The north star is legibility. If you can point at the board and explain what happened, the system is doing its job.

Nouns, verbs, adjectives

Ruboria uses a small systemic language so cause and effect stays readable.

  • Nouns are things like tiles, tools, creatures, machines, and props
  • Verbs are actions like cast, stamp, weld, mend, pull, push
  • Adjectives are states like Wet, Hot, Approved, Brittle, Insulated

Gridcasting applies verbs and adjectives in a tetromino pattern, so board logic and world logic stay in sync.

Example chain

You place a water mino. Tiles become Wet. A spark mino lands next. Conductivity travels. A brittle seam pops. A path clears. One decision, several consequences.

Good play looks like planning. Bad play looks like the board getting away from you.

World layers

Ruboria is built as a layered world. Civic is a calm sanctuary for repairs and toys. Adventure is where pockets of danger and puzzles live. The same systems apply in both places, but the tone and stakes change.

Civic

Towns, hubs, permits, routing, and gentle machines. A place to tinker, fix, and socialize.

  • Gadget contraptions that feel like toys
  • Maintenance as endgame, not filler
  • Tools and paperwork as a real mechanic

Adventure

Encounters that reward setup and cooperation. The board is strict, tile-aligned, and consistent.

  • Localized pockets so the world stays responsive
  • Systemic reactions that you can learn and master
  • Failure is usually mendable, not a dead end

Permit Dominoes

One approval bumps the next. The stamp travels. The gate finally opens.

Gear Chorus

Three small wheels keep a civic lamp from flickering back into nonsense.

Marble Lift

A rolling bead triggers a latch, raises a plank, and resets itself politely.

Ink Conduit

Route a flow to calm a seam. Sometimes the cure is just a better path.

Ribbon Relay

Messages and maintenance tasks move along a tidy line, like a parade for paperwork.

The world remembers

Ruboria is not a stage that resets the moment you walk away. The world keeps a record of what has been repaired, what has been discovered, and who did it first.

Persistent outcomes

When a civic system gets fixed, the world treats it as fixed. A route can stay clearer. A hub can feel more stable because people did the work.

Recorded discoveries

When players prove a new maneuver or pattern, it can be recorded and credited. It is a small kind of immortality in a world that is always trying to fray.

You do not need to know every secret to enjoy Ruboria. Curiosity is rewarded, not required.

Server and netcode

Ruboria is built to scale like an MMO and behave like a game with rules you can trust. The design leans on deterministic simulation, a fixed tick, and pocket-based load separation.

Deterministic tick

Board logic runs on a fixed 20 Hz server tick with deterministic rules. Physics is visual. The authoritative state is the grid.

  • Consistent outcomes across clients
  • Better replay and debugging
  • Fewer edge cases from floating drift

Pockets and volume nodes

The world is split into active simulation pockets so crowded areas do not drag down everything else. Capacity is managed by tick budget, not by hoping the server holds.

  • Server enforces a per-tick budget
  • No live pocket migration during load
  • Scale-out is driven by tick utilization thresholds

Bandwidth efficiency

Replication is chunk-based with interest management and delta updates. Most players only receive what they can affect or see.

  • 32 by 32 chunk deltas for tile state
  • Bit-packed updates and short messages
  • Hash-grid style interest filtering

Cheat-resistance posture

Movement can feel responsive, but outcomes are validated server-side. The goal is not perfect prevention. The goal is a fair, stable world.

  • Server-authoritative logic for grid outcomes
  • Client prediction where it helps feel, with visual correction
  • Simulation budget protected from networking spikes

Operational discipline

The tick loop is designed to stay allocation-free so it does not jitter under load. When the server detects a rare incident, it can compensate players online with a small make-good.

  • Preallocated buffers and ring telemetry
  • Separate simulation and network budgets
  • Capacity planning based on real tick cost

Monetization stance

FAQ

What kind of MMO is Ruboria?

It is a fantasy MMO focused on systems, tactics, and persistent world change. The core combat layer is a tile board, while the broader world supports exploration, repairs, and social hubs.

How does combat work?

You gridcast. Choose a tetromino ability, preview placement, then commit it to the board. Reactions are systemic and readable, with consistent rules you can learn.

How does progression work?

Progress is tied to what you do, not just what you kill. Repairs and order-focused play feed civic progress. Experiments, clever chains, and risky solutions feed mastery. Discoveries can become recorded maneuvers.

Is Civic safe? Is Adventure always dangerous?

Civic is designed as a sanctuary for toys, permits, and maintenance. Adventure is where the strict board encounters live. Both layers share the same world rules, so skills transfer.

What is playable right now?

Development is ongoing. When playtests open, invites will go through the signup list. Short clips and system demos are posted on YouTube.

What is the monetization plan?

Buy to play. No pay to win. No loot boxes. If that policy ever changes, it will be stated plainly.

Where should I follow the project?

YouTube for clips and demos. The signup list for playtest invites and occasional updates.

Is Ruboria focused on solo or group play?

Both. The board is readable solo, but many problems are designed to be more interesting with cooperation. Tools and roles are flexible, so groups can adapt without strict class locks.
