Choose Your Mode
A solver-backed 24 game with multiple modes, exact arithmetic, and feedback tools for practice.
Solve chains of puzzles against the clock. Score, streaks, and skip control make it feel like a compact puzzle arcade.
No floating-point rounding. Intermediate fractions are computed exactly so every valid expression behaves as expected.
Daily mode gives the same puzzle to everyone and resets at UTC midnight, making comparison and sharing straightforward.
Every round starts with four numbers. Combine them step by step until one value remains.
Select any two current numbers (or intermediate results) on the board.
Use +, -, ×, or ÷. The two selected values merge into a new result card.
Keep combining until one value remains. If it equals 24 exactly, you solve the puzzle.
Single-puzzle mode for focused solving. Best for learning patterns and practicing clean lines.
Timed run with score and streaks. Use hints and skips carefully to maximize throughput.
Shared daily puzzle with local result tracking and a copyable summary for comparison.
You get four numbers and must combine them using +, -, ×, and ÷ to make exactly 24. Each move combines two values into one until only one value remains.
Yes. The game uses exact fraction math internally, so intermediate values like 1/2 or -3 are valid and evaluated precisely without floating-point rounding issues.
Classic is a single-puzzle mode with no timer. Sprint gives you a countdown and scores multiple puzzles in a row. Daily is a shared puzzle that resets at midnight UTC.
Yes. Puzzles are generated and filtered by a solver before they are shown, so every puzzle in the game is guaranteed to be solvable.
Yes. The hint button suggests a good next move from your current board state, while the solution panel shows one full valid expression if you want to study it.
Start with Classic, race in Sprint, or clear today’s Daily puzzle.
