Suguru
Fill every cage with 1 to its size — and never let two equal digits touch, even diagonally.
The rules
How to play
- 01
The cages
The grid is carved into cages — regions of different sizes, each outlined by a bold border.
- 02
Fill 1 to N
A cage of N cells holds the digits 1 to N, each exactly once. A three-cell cage carries 1, 2 and 3.
- 03
No touching duplicates
No two cells that touch — horizontally, vertically or diagonally — may share the same digit.
- 04
Givens are fixed
Prefilled cells are clues. They anchor the solution and can never be changed.
- 05
Deduce from the borders
Read the cage boundaries against the eight-way rule to work out where each digit has to go.

Five ways to crack the cages
Small cages first
A single-cell cage always holds 1, and a two-cell cage holds 1 and 2. Lock those in before anything else.
Adjacency elimination
A cell next to a placed digit can never repeat it — in any of the eight surrounding directions.
Hidden singles
If a digit fits only one cell inside its cage, it belongs there. Place it and move on.
Pencil the candidates
Note the possible digits for each cell, then erase them as neighbouring placements rule them out.
Mind the diagonals
Suguru checks all eight neighbours, unlike Sudoku — a single digit can block up to eight cells at once.
