Tic-Tac-Toe 3D

This game extends tic-tac-toe into a 3x3x3 cube with 49 winning lines. Students click a glass cell to place an X while the computer answers at Easy, Normal or Sharp level, and they can drag empty space to turn the cube and see cells behind others. Readouts show whose turn it is, the score for you, the computer and draws, the move number and open threats. Teachers can use it for spatial reasoning and strategy talks about which positions are on the most lines.

• Click a glass cell to place your X, then drag empty space to turn the cube and check every line.
• Take the center cell first and notice that it lies on more winning lines than any other.
• Watch the Open threats readout and block the computer when it shows a threat.
• Switch Computer from Easy to Sharp and compare how often you win.
• Use Undo move to test a different choice, and widen Cell spacing to reach hidden cells.

1. 1Identify winning lines along axes, faces and space diagonals.
2. 2Use spatial reasoning to track cells in three dimensions.
3. 3Compare opening moves by the number of lines they control.
4. 4Anticipate an opponent's threat and choose a block.
