The solver is great for checking answers, but the fun is in finding them. Play the 24 Game with a new daily puzzle, levels and hints that show just the next step.
Frequently asked questions
How does the 24 game solver work?
It tries every order of the four numbers, every pair of operations and every way of grouping them, using exact fractions, and lists each different way to make 24.
Which numbers have no solution?
Some sets can't make 24, for example 1 1 1 1, 1 1 1 2 or 1 1 2 2. The solver tells you when there is no answer.
Why do some answers use fractions?
A few tricky sets, like 3 3 8 8 or 1 5 5 5, can only be solved by making a fraction along the way, for example 8 ÷ (3 − 8 ÷ 3) = 24.
Can I use numbers bigger than 13?
Yes. The classic cards go from 1 to 13, but the solver accepts any whole numbers from 1 to 99.
