Tilted

Some games demand your attention. Tilted gives it back. Inspired by the classic handheld tilt-ball toys you couldn't put down as a kid, Tilted is a dexterity puzzle built for the end of a long day. Pick up your phone, tilt it gently, guide metal balls into their holes. No timers. No lives. No pressure. Just you, gravity, and the satisfying click of everything falling into place. 100 LEVELS. 10 WORLDS. Journey through 10 beautifully illustrated worlds — from a sunlit kitchen at dawn to a rooftop under a midnight sky. The further you go, the more tilted things get. PHYSICS & HAPTICS THAT FEEL REAL Your iPhone's gyroscope and accelerometer simulate true gravity. Balls roll, settle, and tumble back out if you push too far. Three layers of haptic feedback bring every roll, drop, and slip to life — tuned to feel like the real thing in your hands. BADGES FOR THE WAY YOU PLAY Achievements that notice things — whether you're an early riser, a patient soul, a speed runner, or someone who refuses to quit. EARN YOUR WALLPAPERS Complete a chapter and unlock a stunning wallpaper from that world — a little reward to carry with you outside the game. PLAYS YOUR WAY Show the timer or hide it. Play one level or ten. Progress syncs seamlessly across all your devices via iCloud. Tilted is a game about finding your calm by losing your balance — just a little. Go on. Get tilted.
