Fly a little UFO home through mazes in space. Tilt your phone to steer, collect the gems to open the way out, and keep away from the lava. A small alien borrowed the family saucer and flew straight into a comet storm. Now the saucer is dented, its engine is in pieces, and home is a long way off. You fly it back, one maze at a time. HOW IT PLAYS Tilt your phone and the saucer drifts that way, a bit like rolling a marble around a box. It's a little wobbly on purpose, so you learn to fly gently. Whatever angle you're holding the phone at when a level starts counts as flat, so you can play sitting up, lying down or on the bus. If you'd rather not tilt, switch to an on-screen stick in Settings. Collect every gem in a maze to open the gate, then fly through it. Lava damages the saucer, and a few hits will bring it down. The bigger mazes have checkpoints, and the ship's computer explains each new thing the first time you run into it. EVERY WORLD PLAYS DIFFERENTLY You'll fly past lava pools and erupting vents, slide across ice, open doors with switches, carry batteries with a tractor beam past lasers, slip through wormholes, and dodge falling comets in the dark. MORE TO DO - Find the small lost creature hidden in each level and bring it home with you. - Earn stars on every level for finishing, for finishing without a scratch, and for finishing fast. - Follow the story between worlds, told through messages from home. - Spend what you collect on new saucers, hats and trails. - Compete on Game Center leaderboards and unlock achievements. ALSO - Music, sound effects and vibration, each with its own switch. - Plays on iPhone, iPad and Apple TV. On Apple TV, steer with the Siri Remote or a game controller. - Plays offline. Ads and Game Center need a connection. - No account needed. Your progress stays on your device. ADS AND PURCHASES UFO Puzzle is free and has ads. Video ads only play when you choose to watch one, to repair the saucer or to double what you earned in a level. You'll sometimes see an ad between levels, but never during one. A one-time purchase turns those ads off. You can also buy in-game currency to unlock looks sooner, but you never need to: everything can be earned by playing. There are no ads or purchases on Apple TV.
