What game do space explorers play?

Instructions

This is a version of the traditional tic-tac-toe game (also known as noughts and crosses) where you play against the computer. This game is suitable for older children to play as it is clever about where it puts its pieces and hard to beat!

Click the green GO! button to start, then follow the simple instructions below the tic-tac-toe grid.

This game requires the Adobe Flash plug-in. See the Getting Started Help pages, in the section "What do I need to view this site?" for more details.
