24 Game
Play 24 free in your browser — no download, no sign-up. Four card values, use each once with + − × ÷ and parentheses to reach exactly 24. Every puzzle ships with all solutions, step hints and combo scoring.
24 is a classic mental-math puzzle: draw four numbers (like playing cards from 1 to 13) and combine them with basic arithmetic so the result is exactly 24. Each number must appear once. It trains order of operations, fraction tricks and fast arithmetic — and it's satisfying when a tough hand suddenly clicks.
Why Play Here
Runs entirely in your browser. No app, no account — load the page and a solvable puzzle appears instantly.
Every round lists every valid expression, highlights the shortest optimal path, and offers three step-by-step hints before revealing the best answer.
Rules in One Minute
Use all four numbers exactly once. Allowed: + − × ÷ and parentheses. Face cards count as J=11, Q=12, K=13, A=1.
Submit when your expression evaluates to 24. Skip if stuck — the optimal solution is shown and the next round begins. Using hints still scores points, but fewer than a clean solve.
Scoring & Combos
A solve without hints earns 20 points; with hints, 10. Three or more correct rounds in a row add combo bonus (+5 per extra streak step).
Your total score, best combo and last ten rounds are saved locally in your browser.
Quick Tips
- Look for pairs that multiply to 24, or to a factor of 24.
- Division often needs parentheses — try grouping early.
- When stuck, hint step 1 breaks the optimal path into smaller sub-expressions.
- Browse the solution list to learn patterns, then retry without hints.
- Keep a streak going — combo bonus adds up after three correct rounds.
