WARNING: THIS IS HARD!
Think A Dot is a puzzle game with 127 levels where you are challenged to match a color pattern (small pattern on the right)
This is achieved by dropping marbles in the three gates at the top which will change the colors in the eight holes. Each hole contains a switch which switches when a marble passes. This causes the marble to take a different route the next time (enable the "Look inside" option to reveal this mechanism)
This game is inspired by the mathematical Think-a-Dot toy made by E.S.R., Inc. during the 1960s which demonstrates group theory (see http://en.wikipedia.org/wiki/Think-a-Dot)
TIP: you can also reset the game by touching the moves label on the left
