Tilt your phone to roll balls through a maze of rings toward the center. Gravity affects every ball at once, so getting one ball where you want it often sends the others somewhere you don't. Promote one, sacrifice another.

At heart it's a calm game, something to practice, like a marble maze or a wooden labyrinth you balance by hand. Four levels suit different moods, from calm and meditative to genuinely demanding. The levels are all unlocked from the start, so you can play whichever one feels right.

The optional timer is off by default. Turn it on whenever you want something to measure against.
