# Medium Shikaku

A medium Shikaku allows rectangles up to six cells, so a number has more shapes and more places each shape could sit. It is the grade most solvers settle on.

## How to solve a shikaku

Cut the grid into rectangles so that every rectangle holds exactly one number and has exactly that many cells. Every cell ends up in one rectangle, and no rectangle may hold two numbers.

### The method

1. Start with the numbers that have only one shape. A prime number is a single row or a single column and nothing else, so a 5 or a 7 is already half placed. A number as wide as the grid has nowhere to slide at all.
2. Use the other numbers as walls. No rectangle may contain two numbers, so a shape that would swallow a neighbouring clue is out. On a crowded board that removes more options than the sizes do.
3. Look for cells only one rectangle can reach. Corners and edges are the place to look: a cell in the corner can only be covered by rectangles that reach into it, and often there is just the one. That is the same move the solver makes, and it is usually the first real foothold.
4. Count what is left. The numbers always add up to the number of cells, so once a region is sealed off the clues inside it must account for exactly its area. A region that comes up short or long means something earlier is wrong.

**The one rule**

Rectangles only, one number in each, area equal to that number, every cell used exactly once.

**What the answer page shows**

The finished cut is printed at the back.

**How the grades differ**

Harder grades are bigger boards that allow bigger rectangles, so each number has more shapes it could be and more places each shape could sit.

**Good for**

Solvers who like times tables and a tidy finished page.
