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 younger school-aged children to play as it is quite clever about where it puts its pieces!

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.
