Tumblestone

Tumblestone might appear to be your average match-3 tile game, but it's actually a forward-thinking puzzler that pushes your analytical skills to the max and brings about the best in mankind.

Most of the time you'll be facing a single puzzle where you have to remove all of the blocks. Different gimmicks are introduced every world and the difficulty curve is pretty smooth. If you get stuck on a level I recommend taking a break and coming back to it later because Tumblestone is the type of game that's easy to jump in and out of.

This isn't like Tetris or Puzzle League. Those games are reactive. The only instances where time is a factor is during boss battles and multiplayer. Most of the single player campaign has you learning the nuances of each doohicky and special effect. It's a lengthy adventure too-- 360 stages. Get moving.
