About this tool
24 Game is a free online game. Make 24 from four cards with + - x /, solver included. Play instantly — no install, no waiting. It runs entirely in your browser — no download or sign-up needed.
The system randomly gives 4 numbers from 1 to 13 (analog playing cards). You need to use addition, subtraction, multiplication, division and parentheses to combine these 4 numbers into 24. Each number must be used once and only once. For example, given 3, 3, 8, and 8, the answer is 8 ÷ (3 - 8 ÷ 3) = 24.
Some questions have multiple solutions, some questions have only one solution, and very few questions have no solutions (the system guarantees that all questions given have solutions). You can try simple combinations first, and try complex nested parentheses if not.
Exhausted all possible operation combinations: full permutations of 4 numbers (24 types) × operator combinations (4³ = 64 types) × bracket positions (5 structures), a total of less than 8000 possibilities, which can be verified by the computer in an instant. The prompt function displays a feasible solution.
In the blackjack game, use the given 4 numbers to make 24 through addition, subtraction, multiplication, division and parentheses to test mental arithmetic and combination skills.
