## Plus Advent Calendar Door #18: Square it!

Submitted by Marianne on December 18, 2015Here's another game from Wild Maths. On a square grid, take turns marking the corners of the grid. The first person to claim all four corners of a square wins. Can you find a winning strategy?

You can try this with a friend using squared paper, or you can play against your friend or the computer with the interactivity on Wild Maths.
