#11 Lumines
Lumines is a somewhat modified concept of Tetris, which focuses instead on the grouping of four blocks or more of the same color stacked together in a square or a variation thereof.
The biggest aspect of Lumines comes not in its puzzle aspect, but in the music that plays in the background which changes to the actions of the player.
Versions of Lumines are available on a variety of platforms including the PlayStation Vita.
