Game rules

In the game, you make a sequence of moves. You start with a cross made of points in grid intersections. Each move consists of placing a new point at a grid intersection and drawing a new line segment connecting 5 consecutive points that include the new one. The line can be drawn in any of the four directions: horizontal, vertical, or either diagonal. Two line segments with the same direction are permitted to share one point.

The aim of the game is to make as many moves as possible.

Good luck!
