Here'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.

Wild Maths encourages students to explore maths beyond the classroom and is designed to nurture mathematical creativity. The site is aimed at 7 to 16 year-olds, but open to all. It provides games, investigations, stories and spaces to explore, where discoveries are to be made. Some have starting points, some a big question and others offer you a free space to investigate.
