Globetrotters Free is a free, simple iPad arcade game with same-screen multiplayer for up to four people. The product of a 48-hour indie "game jam," this space-themed, diamond-collecting game is a "free gift" from the developers behind the inventive desktop arcade-puzzler And Yet It Moves.
You can play Globetrotters solo, but it's most fun with multiplayer: up to four people can join in, one on each corner of the device. Each player controls an astronaut (red, yellow, blue, or green) using just one thrust button. The trick is timing your thrusts while your astronaut slowly spins and passes through the gravity wells of a handful of planets. Your goal is to land on planets, walk around on them as you whittle them down into diamonds, and then collect any free-floating diamonds left behind. Of course, it's even better to collect diamonds that another player has mined, and the action is frantic as all the astronauts streak around and off the edges of the wrapping screen (with AIs controlling any of the four astronauts not taken by human players). You play through a series of rounds, trying to collect the most diamonds, and occasionally diamond-studded asteroids streak across the screen, which can help you either catch up or widen your lead.
There's not much depth to Globetrotters, but it's such a charming, well-done little game that it's definitely a worthwhile download for anyone interested in fun same-device multiplayer games on the iPad.
