Tic-tac-toe: witch vs slime

You are the witch 🧙, the AI is the slime 🟢. Get three in a row — across, down or diagonally — to win!

Mode
0 0 Draws 0

How to play

Players take turns placing their mark on the 3×3 board. The first to line up three marks in a row, column or diagonal wins; if the board fills up with no line, it is a draw. The starting player switches every round. Tap a square, or press 1–9 on the keyboard (top-left to bottom-right).

AI levels

Easy plays randomly. Normal takes a win when it sees one and blocks your obvious threats, but can be tricked with a fork. Impossible uses the minimax algorithm to search every possible game — the best you can do is a draw.

Tips

Taking the centre or a corner first gives you the most winning lines. To beat the normal AI, aim for a fork: a move that creates two threats at once, so only one can be blocked.
