Set a secret number, date, passcode, or time. Challenge friends or match with strangers. The fewest guesses wins!
Four unique ways to stump your opponent. Set a secret, watch them sweat.
Pick a secret number. Difficulty levels from Easy (1–10) to Extreme (1–10,000). Higher or lower hints guide your opponent.
Set a secret date — month, day, year. Earlier or later clues narrow it down. Who really knows your date-sense?
Create a secret PIN. Locked digits reveal positions. Crack it digit by digit before your opponent cracks yours.
Hide a secret time on the clock. Hour, minute, AM/PM — each locked component narrows the search.
A full game takes just minutes. Best played with friends.
Choose from Number, Date, Passcode, or Time. Each has multiple difficulty levels.
Enter your secret value. Your opponent will never see it — they figure it out from clues.
Both players guess at the same time. Real-time feedback after every guess.
The player who cracks the secret in fewer attempts wins. Tie? Rematch!
