How to play

In each shape, find a number made from two other numbers. Tap the answer. Use three different cells for an equation.

Addition: find the sum.
Multiplication: find the product.
Subtraction: find a difference shown. With 14, 6 and 8, either 6 or 8 works.
Division: find a whole-number quotient shown. With 24, 4 and 6, either 4 or 6 works.

Each solved shape becomes one large answer. When all shapes are solved, those same numbers form the final puzzle, using the same operation and rule.

Addition and multiplication have one correct answer. In subtraction and division, any valid answer counts, and every choice leads to a solvable final puzzle. Repeated numbers are separate cells; use three different cells for each equation. No negative numbers or fractions. Use Tab and Enter or Space to play by keyboard.
