About Tic-Tac-Toe 3D
Tic-Tac-Toe 3D stacks the boards into a cube. On the small 3 by 3 by 3 cube you need three in a row, on the big 4 by 4 by 4 cube four in a row, and a line can run across one board, straight up through all of them, slanting up through them, or from one corner of the cube to the opposite one: the big cube has 76 lines. Tap a square to play, drag to turn the cube, and use Undo and Hint when you need them.
Climb a ladder of six robots, from Pip and Bolt on the small cube to Rusty, Gizmo, Nova and Max on the big one. Each blocks better and plans further ahead than the one before: Nova makes forks (two lines at once), and Max looks ahead at your replies. Beat a robot to open the next one, beat it three times for three stars, and spend coins on piece colours. Or pick 2 players and pass the phone.
With red-green, red-blue or red-cyan 3D glasses the boards float one above the other, which makes lines through the layers much easier to see. It plays in colour without glasses too. Robot tournaments check that every robot blocks every line, that each level is stronger than the last, and that every robot can be beaten.
