Crossmoor: Tic Tac Toe 3x3 5x5
Tic tac toe on stone: classic 3x3 or wide 5x5 four-in-a-row, vs AI or a friend.
Crossmoor brings the oldest board game in the world out onto a quiet heather moor. Heather crosses meet rings of moss on a weathered stone slab, and every match is a short, calm duel of wits - against the moor spirit or against a friend sitting next to you.
How To Play
- Pick your board: the classic 3x3 grid or the wide 5x5 slab.
- Pick your opponent: the moor spirit (Easy, Fair or Sharp) or Two players on one phone.
- Take turns tapping empty cells. On 3x3, line up three marks. On 5x5, line up four - across, down or on a diagonal.
- The first to complete a line takes the moor. Fill the board without a line and it is a quiet draw.
