Make 24 Rules
Make 24 is a classic math puzzle: you are dealt 4 number cards (1–13). Use addition, subtraction, multiplication and division to make exactly 24 — every card must be used exactly once. For example, 3, 3, 8, 8 is solved by 8÷(3−8÷3)=24. Every deal on this site is checked by a built-in solver and guaranteed solvable. Stuck? Hit Hint for the first step, or Undo a wrong move.
Common Strategies
- Aim for products: try to build the classic pairs 4×6, 3×8 or 2×12 first.
- Think 24±x: reach 24 plus or minus something, then find a way to cancel the remainder.
- Use division creatively: many hard deals require fractional intermediate values — don't shy away from fractions.
Arithmetic as a Sport
The modern 24 game was published in 1988 by Robert Sun, an engineer who wanted children to see arithmetic as something you can be fast and creative at, not just correct at. His decks of numbered cards spread through classrooms worldwide, and the format — four numbers, four operations, one target — has kept families and math clubs happily arguing ever since.
The real skill it builds is flexibility: the willingness to try 3 × 8, abandon it, and spot 4 × 6 hiding in the same four cards. Many deals have several different solutions, and finding a second route after the first is where the mental gym really happens. It's one of the few games that works as genuinely useful homework — ten minutes a day visibly sharpens mental arithmetic for kids and adults alike.
الأسئلة الشائعة
How do you play Make 24?
Combine the 4 number cards with addition, subtraction, multiplication and division to make exactly 24. Each card must be used exactly once. Click in order: number → operator → number.
Is every deal solvable?
Yes. Every deal is verified by a built-in solver before it reaches you, so a solution always exists. Stuck? Hit Hint for the first step.
Where did the 24 game come from?
It originated as a Chinese playing-card pastime and is now widely used around the world for math education and brain training.
What are the benefits of playing?
Make 24 sharpens mental arithmetic, number sense and logical thinking — great for students and adults alike.
Can I use each number card only once in Make 24?
Yes — the standard rule is that each of the four cards is used exactly once, and every operation is applied to results you already have. Intermediate values may be negative or fractional; as long as the final expression equals 24, it counts as a valid solution.
Who is Make 24 good for?
Anyone who wants faster, calmer mental arithmetic: schoolkids building multiplication fluency, adults who want a five-minute daily warm-up, and families — it's one of the rare games where a sharp ten-year-old can honestly beat a parent.
