Intelligence Cross a kind of entertaining play. You can have more fun when all the checkpoints are in the style of vivid pictures. The rules of the game is very simple, you just draw all the pictures as per the pictures that have been shown. However, the line cannot be overlapped; the game is getting harder to play when more checkpoints have been passed through. There are some very specific rules for the game, for instance, the line that has to pass twice, the line that has to pass from one direction, and jump points that have to remove to another point etc.
