The free version features 14 songs and a basic drum kit with 8 zones to tap; spend a buck to take that to more than 40 songs and bigger, badder drum kits. Just tap the colored circles as they pulse up through the super-clean interface (with or without labels for each item in your kit) with hip hop, club, industrial, jangly pop, heavy metal, or good old rock & roll drum samples, all of which sound crisp and fresh.
After you’ve mastered the in-game patterns -- which seems unlikely at anything beyond the easy skill level, because they get finger-twisty quickly -- you can download player-made patterns or create and upload your own. It’s a shame there’s no way to quantize the beats you tap out; any rhythmic mistakes you make are presented raw to the world.
The bottom line. For free it’s a fun and elegantly designed distraction; even if you splurge for the in-game Pro Gear Pack, it’s hard to argue with a buck for all this content. It all comes down to how much and how often you want to play Simon with a 27-piece drum kit.
