Hex
The classic game of Hex against a Monte-Carlo AI. Place RED stones to connect top and bottom before the AI links left and right with BLUE. Full two-way swap (pie) rule, undo, highlighted winning path and three board sizes 7×7 / 9×9 / 11×11 — Hex can never end in a draw.
Goal: Connect the two RED edges (top and bottom) with an unbroken chain of red stones before the AI connects the BLUE edges (left and right). By the Hex theorem a full board always has exactly one winner — draws are impossible.
- Tap / click an empty hexagon to place a stone
- ⇄ Swap (pie rule): right after the FIRST move of the game, the second player may steal it — the stone flips color and mirrors its position. The AI will swap too if your opening is too strong!
- ↶ Undo takes back one pair of moves (yours + the AI's reply)
- New: pick who moves first (you / AI / random) and start a fresh game
