Plumb

Tilt the board and every marble rolls at once. Get each ball into the hole of its own colour, and keep them out of the square pits.

Swipe in one of four directions. Every marble keeps rolling until a wall, an edge or another marble stops it. A good move changes the path for every marble, so take a moment to read the board before you tilt.

The chapters bring new rules, including gates, portals, springs, magnets and glass. Earn stars for solving a level in fewer moves, use a hint when you want a nudge, or try the shared daily puzzle. Undo and restart whenever you like. There are no timers, lives or energy limits in the levels.

Plumb has colour themes, an ambient soundtrack and puzzles you can play offline.
