24

MathsArithmeticSingle playerStreak

Four cards, four operations, one target. Every deal here can be solved.

Controls — Tap two cards, then an operation. No keyboard needed.

How to play

  1. Combine the four cards with + − × ÷ until one card is left.
  2. Tap two cards, then tap an operation — the pair merges into one card.
  3. The deal is solved when the last card is exactly 24. Undo is free.

Tips

  • Look for 6 × 4, 8 × 3, 12 × 2 before you start combining at random.
  • Fractions are allowed and often necessary: 8 ÷ (3 − 8/3) = 24.
  • If three cards make a useful number, merge those three first and keep the fourth for the end.

About this game

24 is the arithmetic game with a solver behind it: deals are only dealt if a solution exists, so a stuck hand means a missed combination rather than a dead deal.

Fractions are exact here. Nothing rounds, which is why 8 ÷ (3 − 8/3) reads as 24 and not 23.999.

FAQ

Can I use a card twice?

No. Each of the four cards is used exactly once.

What if I get stuck?

Hint works on a fresh deal: undo your merges first and it shows one full solution. Undo takes you back one merge at a time.

Do the cards go up to 13?

Yes — values 1 to 13, like a deck without suits.
