Exact 24

Hints + Undo

Classic 24

Solve one puzzle with clean steps.

Target Number 24

Built for Repeat Play

A solver-backed 24 game with multiple modes, exact arithmetic, and feedback tools for practice.

Sprint Mode

Solve chains of puzzles against the clock. Score, streaks, and skip control make it feel like a compact puzzle arcade.

Exact Fraction Math

No floating-point rounding. Intermediate fractions are computed exactly so every valid expression behaves as expected.

Daily Reset

Frequently Asked Questions

How do you play Knowess: 24?

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.

Can intermediate results be fractions or negative numbers?

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.

What is the difference between Classic, Sprint, and Daily?

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.

Does every puzzle have a solution?

Yes. Puzzles are generated and filtered by a solver before they are shown, so every puzzle in the game is guaranteed to be solvable.

Can I get a hint without revealing the full solution?

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.
