Costcodle

Costcodle is a free daily Costco price guessing game. Every day there is one warehouse item and six guesses to land within 5% of its price. After each guess the receipt says go higher or go lower, and flags you as close once you are within 25%. A new item arrives at 00:00 UTC, with no account needed.

Play

• Today's Costcodle
• Costcodle Unlimited: endless practice rounds with past items, separate from the daily streak

Open source

costcodle-rules is the rules engine behind the game: guess judging, price parsing, the UTC daily schedule and the spoiler-free share text. Pure TypeScript with no dependencies, MIT licensed, also on npm.
