Orb Flo is a puzzle game comprised of a set of prisms and receptacles. A puzzle is considered solved whenever the orbs flow through all receptacles. Flow can be altered by toggling a prism on or off.

The game has three different modes: practice, time-trial, and endurance. In time-trial mode, you are ranked based on how quickly you solve ten puzzles. In endurance mode, you are ranked by how many puzzles you can solve using a set number of lives. A life is deducted if you use up too many moves to solve a puzzle.
