YesNoMystery

A lateral thinking puzzle is a reasoning game where you can only get yes/no/irrelevant answers to deduce the truth behind mysterious scenarios. It tests logical thinking and creative reasoning abilities.

We use advanced AI technology that can understand your questions in most cases and provide reasonable yes/no/irrelevant answers based on standard solutions. The AI has been trained on numerous lateral thinking puzzles with about 85% accuracy. If you encounter judgment discrepancies, try asking from a different angle.

Credits are the in-game currency. Each AI question costs 1 credit in Standard mode and 2 credits in Fast mode; viewing hints costs 1-4 credits; viewing answers costs 0-30 credits based on progress. Credits never expire and can be earned through check-ins, invitations, or purchases.

Get 100 credits after registration, refresh 30 free credits daily, and earn 50 credits when an invited friend completes their first successful AI question.

After a friend binds your code and completes their first successful AI question, you both receive 50 permanent credits. Up to 10 friends per inviter can earn rewards each UTC month.
