Flow Free

Flow Free is a grid-based puzzle game where you connect pairs of colored dots with continuous lines. Each puzzle gives you a board with several dot pairs—your job is drawing paths between matching colors without crossing any lines, and every square must be filled. Early grids might be 5×5 with three colors; later ones expand to 14×14 with a dozen pairs competing for space. The core challenge is planning routes that don't box each other in. You can tackle hundreds of static puzzles at your own pace or switch to Time Trial mode for pressure. Difficulty scales from quick warm-ups to head-scratchers requiring multiple attempts. No story, no upgrades—just you versus the grid.
