How to play Make 24

Use a short break to learn the rhythm of Make 24. Use all four numbers exactly once to obtain 24. Look at what changes after your first action. Compare the starting position with the example in the Guide. Check the relevant rule before repeating a move.

Each generated starting set has a verified solution; fractions are allowed.

Focus on one rule

Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Use the example to check your reasoning.

Your goal

Use all four numbers exactly once to obtain 24. An attractive position is not enough unless the goal is met. The example below illustrates a decision.

Step by step

1. Choose two values in order.
2. Choose addition, subtraction, multiplication or division.
3. Combine and repeat.
4. Undo explores alternatives; Show solution reveals a verified expression.

Controls

Tap two values, an operation and Combine. Read a button’s label before selecting it. Use one clear input at a time.

A useful example

Using 1, 2, 3 and 4 once each, (1 + 3) × (2 + 4) equals 24. Brackets determine which operations happen first. Compare this with the rule that governs the move. Notice the change in the playing area.

Watch out for this

Division and subtraction depend on selection order; zero division is blocked. Check the rule before repeating the action. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
