About Flow Free

Flow Free is one of the most popular logic puzzle games of all time, celebrated for its simple rules and deeply satisfying gameplay. It’s a game of spatial reasoning and planning — easy to pick up, but increasingly challenging as you progress through larger grids and more color pairs.

Each level features a grid with pairs of colored dots. Your task is to connect each pair with a continuous line that fills the grid squares between them, with the critical rule: no lines can cross each other. The puzzles start small (5x5 grids) and grow to complex 15x15 challenges that test even the most seasoned puzzle solvers.

Our version of Flow Free is 100% free to play, with no ads or in-app purchases. It includes hundreds of levels across four difficulty modes, a hint system for tricky levels, and progress saving — perfect for brain training or casual puzzle solving on any device.
