Chromata.
A code is deduced, never guessed.

Chromata is a logic puzzle where you never guess — you prove. A secret code hides behind three, four or five colors, each carrying a value from 1 to 5. Each turn, three statements are offered to you, with no verdict attached. You pick only one, and only then does the game reveal whether it is true or false. That is the whole point: if “Iris > Cobalt” is false, then Iris ≤ Cobalt, and you have learned exactly as much. No bad draw, no luck to suffer — only reasoning that is more or less efficient. Cross out impossible values on the grid, cross-reference, narrow it down, and when one candidate is left, submit it. Every game can be replayed statement by statement afterwards, and there are seven ranks to climb, from Greyness to Divine Lagoon. A game lasts two to ten minutes, plays in silence, offline, with no account and no ads. The game is free; a single purchase, never a subscription, unlocks 4 and 5-color codes, hard mode and timed mode.
