Chromata.
A code is deduced, not guessed

Chromata is a solo logic-deduction game. A secret code hides behind three, four or five colours, each carrying a value from 1 to 5. Every turn you are offered three statements — without their verdict. You pick one, and only then does the game reveal whether it is true or false. That is the whole point: a false statement teaches you exactly as much as a true one. No bad draws, no bad luck to endure, only reasoning that is more or less efficient. Cross out impossible values on the elimination grid, cross-reference, narrow it down, and when a single candidate is left, submit it. A game lasts two to ten minutes, plays in silence, offline, with no account and no ads.
