RuleMarket: Hidden Rules

A new hidden-rule puzzle every day. Probe the tiles, read the clues, and crack the rule in as few tries as you can then challenge your friends.

Every RuleMarket puzzle hides a secret rule. Your job: figure it out.

Probe a row of shapes, watch each guess come back PASS or FAIL, and use the clues to deduce the hidden rule in as few probes as you can. Easy to learn, genuinely hard to master.

• THE DAILY: one fresh rule every day, the same for everyone. Solve it to build your streak (a streak-freeze covers the day you miss). • ENDLESS PLAY: puzzles that never run out, from Easy to Brutal. • BEAT PAR: every puzzle has a par. Solve it under par with no wrong guesses for a 3-star result. • STUCK?: spend a hint to rule an answer out. • SHARE THE WIN : spoiler-free result cards. "Can you find the rule?" • MAKE YOUR OWN: build a rule and publish it to the community, and play puzzles made by other solvers.

No accounts. No ads. Just pure deduction.
