How to play Maths Cage Puzzle

Maths Cage Puzzle is a maths logic puzzle: fill the grid so every row and column has each number once, and every cage makes its target with its sign. It mixes logic with mental arithmetic — adding, multiplying, subtracting and dividing — and teaches factors along the way.

Tips to get better at Maths Cage Puzzle

  1. Start with one-square cages and with cages that have only one possible pair (3+ must be 1 and 2).
  2. For × cages, think of factors: 12× in two squares on a 4×4 grid must be 3 and 4.
  3. After every number, check its row and column for clashes.

Maths Cage Puzzle — questions

What is a maths cage puzzle?

A number grid where every row and column has each number once (like sudoku) and the squares are grouped into cages. Each cage shows a target and a sign: its numbers must make that target.

Is it free?

Yes — free in the browser on phones, tablets and computers, no download.

Does every grid have only one answer?

Yes. Before a grid is shown, a computer solver tries every possible filling and the cages are drawn again until exactly one filling works.

How should my child start?

Begin with the 3×3 grids. Look for cages with only one way to make the target — two squares making 3+ must be 1 and 2. Then use the rows and columns.
