Math Cages

Fill the grid with no repeats — every cage must hit its target.

Interactive lesson1 / 4
Rule 01

Every row and column holds each number once.

A 4 by 4 board uses 1 to 4, a 6 by 6 board uses 1 to 6. Repeat a number in a row or column and both squares are marked until one of them changes.

Rule 01Every row and column holds each number once.

A 4 by 4 board uses 1 to 4, a 6 by 6 board uses 1 to 6. Repeat a number in a row or column and both squares are marked until one of them changes.

Rule 02Every cage reaches its target.

The clue in a cage’s corner is a target and an operation: 7+ means its numbers add up to 7, 12× means they multiply to 12. A number may repeat inside a cage if it is not in the same row or column.

Rule 03Minus and divide work either way round.

A − or ÷ cage has two squares: take the smaller number from the larger, or divide the larger by the smaller. Either square may hold the larger number.

Rule 04Every day has exactly one answer.

A one-square cage is a given and is filled in for you. Stuck? A hint fills in, or corrects, one square from the answer.
