The only rule is that all lines must be traced in one stroke without tracing any lines more than once. If your finger is lifted, all your progress is gone. If you try to redraw lines, nothing will happen.
Before introducing compound lines, the user could only connect directly adjacent vertices. As a result, point 5 and 9, in the example below, could not be connected directly. Instead, the user would try to connect 5 to 9, which seem to be connect in a straight line, but the game wouldn't snap to 9.
The added ability to directly connect compound lines eliminated the feeling that the game was broken. The feature has been much appreciated by users.
