Tic Tac Toe
FreeX and O four ways. Classic 3×3, Infinity (each side keeps only its three newest marks, so nobody can sit back for a draw), and 5×5 or 6×6 boards where you need four in a row. Play the computer on Easy, Medium or Hard, where Hard never loses a classic game, or a friend on the same screen. Five rounds a match, with a hint and an undo when you need them.
Controls: Click or tap a square. Pick the mode and opponent on the start screen. H shows a hint, U or Z undoes your last move.

Tips
- In Classic, take the centre or a corner first. The Hard computer can't be beaten, so a draw against it is a good result.
- In Infinity your oldest mark disappears when you place a fourth, and so does the other side's. Watch which mark goes next.
- On 5×5 and 6×6 you need four in a row. Make an open three, with free cells at both ends, and they can't block both.
- Block a line of three before it becomes four. On the big boards most games are lost by missing one block.
- Hints and undos are there to learn with, but each one costs a few points in that round.
