Put Yourself in a Box

Age 7 to 11
Challenge Level Yellow star
  • Game

This is a game for two players.

You will need:
Two different coloured pencils
A sheet of dot paper (download one) or you can draw your own.

The aim:
To complete as many squares as possible.

To play:
Choose a coloured pencil each and take turns drawing a line by connecting two dots that are next to each other. Your line can be drawn horizontally

( left) , vertically ( down or up) but not diagonally ( bottright or topleft).

When you complete a box put your initial inside it and then take another turn. You can keep drawing lines as long as you can keep completing squares. Don't forget to put yourself in the box!

As you play think ahead. What will be your best move? Your goal is to get as many squares as possible and also to prevent your opponent from getting any.
