A terrific game, Ive no problem with the ads on iPad; they end quickly, Once I memorized the unchanging combinations I could move to challenging and extreme levels but need to keep nearby Brainbashers tables which is online for all possible combinations, not just unchanging combos, Different levels allow you to play to suit your mood and time restraints. I play a lot and never run out of puzzles, Love this game!
