Your aim is to draw as many lines as possible.
To draw a line, click once on the point where it should start, and once in the direction it should be drawn in.
A line can be drawn in eight directions, either horizontal, vertical or diagonal and it always stretches four points/dots away from the origin.
To draw a line, 4 of the 5 dots the line goes though, must be points (bigger).
If a line is drawn through five points (big), you gain one extra "available point" which could be used later.
Available points will be used automatically if you attempt to draw a line without the necessary 4 points, or if you do not have enough available points, the line cannot be drawn.
Lines cannot overlap, but they can start in the same points.
There are four different game plans to play on.
To show places where it is possible to start a line, check the "Hints?"-box in the game.
After clicking on the place to start a line, a blue line indicates that a line might be drawn in a direction, while a red line indicates that a line cannot be drawn.
Use Undo to undo the last line drawn.
Use Redo to redo the last undo-operation, if any.
Use New to start from scratch.
Use the popup-menu called Game plans: to change between the four available game plans.
The game plan grows bigger when lines are drawn near the edges, however there is a maximum board size of 33x33 points.
A hiscore system for the game is also planned.
