Orbitalis

Orbitalis manages to succeed across its hundred-plus level arrangement by literally embodying the "simple to learn, hard to master" concept. Players aren't provided with hints or a tutorial off the bat; instead, the game looks to you to jump into each stage (named after star systems) and test your skills against each gravity puzzle. But as you scratch the surface of the game, you see the brilliant depth hidden in its minimalist presentation. Sure, you can simply accomplish each goal and complete a level, but the time element gives players an additional challenge: Best your time and raise your name on the global leaderboard. You may even be surprised at scanning across the included star map to find little hidden levels off the main path, just waiting for you to explore. In many ways, this gives you a chance to tailor the challenge to your skill level.

But don't be fooled. There's still plenty of challenge to be found in this game, especially when you're on a stage with a dozen or more objects between you and your goal and gravity bouncing your satellite around like a bottle on a stormy sea. The difficulty is a tad inconsistent, with some stages being extremely hard and the next few being a bit too easy. Fortunately, given the many stages, the addition of the daily challenge, and the option to construct your own levels, Orbitalis has more than enough gameplay to please any puzzle fan.
