The 24 Game is a classic mathematical puzzle: given four numbers, use addition, subtraction, multiplication, and division — each number exactly once — to make the result equal exactly 24. It sounds simple. Cards like 1-2-3-4 or 2-3-4-6 have obvious solutions. But many four-number combinations require creative use of operations, unexpected orderings, and sometimes fractions as intermediate values — and some combinations have solutions that take even experienced players several minutes to find.
Cliko Games offers seven difficulty levels from Beginner through Cyborg. Lower difficulties use smaller numbers with many valid solutions; higher difficulties use larger numbers and combinations that have only one or two solutions, demanding creative use of division chains and parentheses. Each session consists of five rounds — solve as many as you can before the timer runs out.
Tap a number card to add it to your expression, then tap an operator (+, −, ×, ÷) and another number. Use parentheses to control the order of operations. When your expression uses all four numbers, tap the "= 24 ?" button to check. If you get stuck, use a Hint (3 per session) or Skip the puzzle with no penalty. The Daily Challenge gives every player worldwide the same puzzle — solve it to build your streak!
The 24 Game has been a classroom staple and competitive math sport since its invention by Robert Sun in 1988. The premise is elegant: four numbers, four operations, one target. It trains mental arithmetic, algebraic thinking, and creative problem-solving in a format that works for ages 8 to 80. Competitive 24 tournaments are held worldwide, with students racing to slam the card first.
