COGNITIVE ARCADE / FREE BROWSER PUZZLES
RULE FLIP
Play RULE FLIP free: switch between ink color and written words across 24 decisions. Daily puzzles, unlimited practice, English and Portuguese.
One word. Two signals. A changing rule.
When a blue word is written in red, your first impulse can send you to the wrong button. RULE FLIP gives you a current instruction: answer the INK COLOR or answer the WORD. Follow it through 24 decisions, with switches every few turns.
How scoring works
A correct response earns 100 points plus a speed bonus of up to 80. An incorrect response deducts 25 points, never below zero, and resets your streak. The maximum score for a round is 4,320. Your device stores your best score, completed games and longest streak.
A useful first practice
Try one practice run without chasing speed. Say the rule to yourself before choosing a button. On the next run, see whether you can keep that accuracy while responding faster. Practice generates a fresh sequence each time.
Controls
Click or tap the four color buttons. On a keyboard, use 1 for red, 2 for blue, 3 for green and 4 for yellow. The rule is always shown above the word. Sound is optional.
Daily challenge and privacy
Players using the same version on the same UTC date receive the same daily sequence. A started attempt resumes in the same browser after a refresh. Local storage and the device clock control this local challenge; changing either can affect it. Records stay in your browser. There is no global leaderboard, account system, paid COMPETITOR access or in-game analytics in this release.
