## Logic puzzle shapes in a grid

**This type of puzzle is based on Sudoku, but it uses shapes instead of numbers. Since the puzzles are for children, they are simplified to a 4×4 grid.**

The theme used in this example of how to solve the puzzle is ‘Viking battle,’ with the symbols of an axe, a sword, a shield, and a helmet.

Not all the puzzle made by SW publisering have a 2×2 grid, so they are a bit more difficult. The principle for solving the puzzle remains the same.

#### The goal

The puzzle is a grid of squares and some of them contains symbols. There are also a 2×2 cell in the grid. It is up to you to figure out which symbol goes in which empty square.

The rules are:

- Every row must contain one of each symbol
- Every column must contain one of each symbol
- Every cell of 2×2 grid must contain one of each symbol
