You can't bend sticks more than a right angle... That is the only rule in the game.
Stick Arts is a simple puzzle game for android phones and tablets that challenge players to draw geometric shapes with pieces of stick.
Here is how to play the game.. Drag a piece of stick into a node of the image (always start with one corner of the stick) and place it along the lines of the image (until the stick is tied to the nodes at both ends of the line). You can bend the sticks from the node. Only thing you can't do is to bend the stick more than a right angle.
If you can't think of a solution, you can always get some hints. (You can easily ask for hints in the first 3 levels. But for later levels, you will have to do some work to get hints). But you will feel better, if you can do it your own. Have fun..
