This month I've been colleting several interesting online puzzles, let's check them out!
This game is really well done. You have to move a piece (resembling the peace symbol) that accumulates up to three states. These states (colors) are enablers to enter to adjacent colored squares. The objective is to reach the star.
Instructions are maybe difficult to grasp at first, but as soon as you start to play they become clear. It has plenty of levels with increasing difficulty. Hard levels are not easy so if you are masochist, this brain teaser is for you.
