Mathematical strategy card game
You and the monkey share one number on the table. Add, subtract, multiply, divide — first to land it on exactly 67 wins. Drop below 0 or push past 99 and you’re out.
How it plays
01
Add, subtract, multiply or divide the shared number. Six ways to move it, and every one of them hands the next state to your opponent.
02
×2, ×3 and ÷2 keep your turn alive. Chain up to six cards — or stop while the number still suits you.
03
Exactly 67 takes it. Four difficulty tiers, from a monkey with no plan to one that has already worked out every way you can win.
The deck

+1 to +9. The only cards that carry you toward 67.

−1 to −9. Pull back from a bust, or deny the monkey a win.

×2, ×3 and ÷2 move the number in leaps — and always keep your turn alive.

Changes nothing and ends your turn. Cycles a dead card out.

Face down to your opponent until it’s played. You always see your own.

A plus or minus card marked COMBO. Play it and the turn stays yours.
