Tic Tac Toe in 3D

So you think you are an expert at the child’s game Tic Tac Toe? Now try it in 3D at MathsNet Interactive! This game was designed in 3D to prevent the first player from always winning. Instead of connecting three in a row to win, you have to connect two rows that meet at a right angle to form an “L”. You are the blue marbles, and the computer plays the part of the red. By clicking and dragging the 3D shape, you can rotate and spin the cube so that you can see your game board from all angles. Check it out! This would be a great follow-up activity to teaching about 3D solids in Geometry, not to mention it would also work well with an Interactive Whiteboard.
