WARNING: THIS IS HARD!
Think A Dot is a puzzle game with 127 levels where you arechallenged to match a color pattern (small pattern on theright)
This is achieved by dropping marbles in the three gates at the topwhich will change the colors in the eight holes. Each hole containsa switch which switches when a marble passes. This causes themarble to take a different route the next time (enable the "Lookinside" option to reveal this mechanism)

This game is inspired by the mathematical Think-a-Dot toy madeby E.S.R., Inc. during the 1960s which demonstrates group theory(see http://en.wikipedia.org/wiki/Think-a-Dot)

TIP: you can reset the game by touching the moves label on theleft
