About Twenty or One
Same seven cards. Two players. One target: hit 20, or hit 1.
Arrange four numbers and three operators into one equation, pick your lane, and land closer than your opponent. Lock in first and you slam the clock on them — that's the squeeze, and it's the whole game.
Best of three. Sixty seconds a round. No accounts, just duels.
THE DAILY
One deal a day, the same one for everyone, everywhere. One attempt — no retries, no second guesses.
HOW A ROUND GOES
Four number cards and three operators, dealt to both players alike. Multiplication and division resolve first, then addition and subtraction, left to right. Every card must be used. There are no parentheses and no discards — only the order you choose.
THE CLOCK IS THE OPPONENT
Sixty seconds a round. At ten the lanes freeze and the clock starts counting in tenths. Lock in before the other player and their clock drops to fifteen.
A fun, fast mental workout that happens to be a duel.
Think fast. Duel harder.
