## How to solve number blocks

Fill each outlined block of k cells with the numbers 1 to k, and never let two equal digits touch, even diagonally.

### The method

1. Size each block. A block of three cells holds 1, 2, 3; a block of five holds 1 to 5. Count the cells to know its digits.
2. Place the givens. Start from the printed digits and the small blocks, where there are fewest choices.
3. Watch the neighbours. A digit blocks that same digit from all eight surrounding cells, so a placed number rules out its neighbours.
4. Work block by block. Fill a block with its missing digits so none clashes with a touching cell, then move to the next.

**The one rule**

Each block holds 1 to its size, and equal digits never touch.

**What the answer page shows**

The completed grid is printed at the back.

**How the grades differ**

Bigger grids and fewer givens mean more to deduce.

**Good for**

Solvers who like a compact, quick logic grid.
