Käsekästchen

Instructions

Gameplay:
Players take turns to draw a single line (horizontal or vertical) between two neighbouring points on the grid.
The aim is to complete the fourth side of a square (or "box").
Complete the box:
Each time a player draws a line that forms the fourth segment of a box, they may mark this box with their own symbol (O or X).
In addition, this player may immediately draw another line.
Additional moves:
If a player completes several boxes in a single move, he may make an additional move for each completed box.
End of the game:
The game ends when all the boxes have been completed.
The player with the most ticked boxes is the winner.
