Turnbox: Gravity Ball Puzzle

Tap, the box turns, the balls fall. Drop the white ones, keep the red one in. 240 levels, 12 chapters and a new machine every day.

One tap. The box turns, the balls fall.

Turnbox is a one-finger physics puzzle. Tap and the box turns 90 degrees; gravity does the rest. Drop the white balls through the exit to fill the level's target, and keep the red ball inside. If the red one falls out or time runs out, the level is lost.

The rule is simple, the consequences are not. Balls that leave in the same turn form a chain and multiply your score. Turn at the last second to save the red ball for a close-call bonus, finish fast for a time bonus, and land spring shots for extra points.

• 240 levels in 12 chapters on one big gear wheel: turn it to bring a chapter to the top • Every chapter ends with a boss level • The first two chapters teach the basics: slopes, sliding blocks, exits that jump, fragile glass balls, heavy iron balls, breakable blocks, a bucket exit in the middle of the box, bouncy rubber walls and turns that reverse direction • From then on, each chapter brings one new mechanic and mixes it with the ones before: springs, one-way flaps, tar, color gates (white passes, red bounces back), steam vents, a steam gauge that counts down your turns, portals, a piston lift that rises one step per turn, dark rooms that hide half the box, and a red push button that turns the box once by itself • Bronze, silver and gold medals on every level • Machine of the Day: a new puzzle every day, with a daily streak and a result to share • Clear levels in a row to build a streak • Endless mode, plus Duo Mode: two boxes, one tap — or duel a friend on one phone • Stuck? Every lost attempt gives you 5 more seconds on that level (up to 15), after 3 losses in a row you can skip it (bosses excepted), and the timer can be set to normal, 1.5× or off • Play upright or sideways, right- or left-handed • 16 languages, reduced motion and haptics options
