Ok, this game really has stumped me at times. It was hard to wrap my brain around how to organize the colors according to the pattern shown. But, after a few days of practicing, I really got the hang of it. However, I also became addicted to it. I started seeing colored dots in my dreams. And then, I became obsessed with beating this game. I started with the Casual mode which allows for unlimited moves and isn't timed. Then I moved on to the Timed level which took me a day or so to get good at. Finally I've moved up to the Limited game mode that only allows for 100 moves to get this puzzle figured out. These 3 game modes will provide you with plenty of challenge and fun.
