Roboroll is a top-down puzzle game in which you navigate a robot through a grid of rotatable passages to an exit panel. Your main obstacle is a limited energy supply; every square the robot moves expends one unit of energy, and if you run out it's game over. Once you get by the introductory levels, there are recharge panels available, which must be visited strategically - use them too soon and you'll waste any energy beyond capacity, but head towards them too late and you could end up breaking down just a few panels away.
The levels are well designed, introducing progressive complexity in the form of enemy robots, door-operating buttons, and teleportation portals. It's not necessary to find the perfectly efficient solution, since no matter how you pass the level you get the same green checkmark and access to the next level. This lack of recognition for perfectionists makes for relaxed gameplay that is found in many of the best level-based puzzle games, a nice change of pace for those stressed by marks of less than 100%.
Topple Drop Free is a puzzle game in which you have different types of blocks.
