A 60-second brain snack
Four numbers.
One answer:
your number.
Add, subtract, multiply, divide — use every card exactly once and land on your number. 24 is the classic; pick any target up to 100. Tap the cards or type the whole expression. Every puzzle is guaranteed solvable.
How it works
Three rules, no tutorial needed.
01
Use all four cards
Every number on the board must be used exactly once — no more, no less.
02
Combine two at a time
Pick a card, pick an operator, pick a second card. They merge into their result.
03
Land on 24
Fractions along the way are fine. Prefer a different number? Set any target up to 100 — 24 is just the classic one.
