7moku is a two-player abstract strategy game played on a 19×19 board. The objective is to be the first player to create an unbroken line of seven of your symbols (X or O) in any direction.
The game is played on a 19×19 grid, initially empty.
Note: Each tile contains both X's and O's, so both players' symbols appear on every turn.
There are six tile configurations. Each tile is a 2×2 grid containing exactly two X's and two O's:
Tile Names:
Important: A tile placement is only legal if all four cells in the target 2×2 area are empty.
A tile cannot be placed if:
A player wins by creating an unbroken line of seven or more of their own symbols in any of these directions:
The game ends immediately when a player achieves this condition.
A unique feature of 7moku is the mutual win scenario. Since each tile contains both X's and O's, it's possible for a single tile placement to create a line of seven or more for both players simultaneously.
When this occurs, the game ends in a mutual victory - both players win!
The game ends in a draw if no legal moves remain and neither player has achieved seven in a row.
In rare endgame scenarios, a player may be forced into an Event Horizon - a state where any legal move leads to the same inevitable outcome (either a solo loss or a guaranteed mutual win). Learn more about this theoretical state.
