content: This is an AWESOME game! Almost everyone know tic-tac-toe so it is EASY to learn and quick to play. You can't play just once! The twist is that your pieces are slightly different sizes - just big enough to gobble up your opponent. The first person to make tic-tac-toe wins, but it's not as easy as it looks when you're stuck in the mindset of just making three in a row and forget about the gobbling possibilities! My 4 and 5 year olds will beat me even when I'm trying to win! Excellent beginning critical thinking game. Grandparents loved playing it with the kids too.
