DotFlow - Simple Brain Puzzle

A free color-flow puzzle: connect matching dots and fill every cell. Train your brain with logic, paths, and a little patience. Perfect as a casual game for a commute, a short break, or a quiet evening. DotFlow is a connect-the-dots logic puzzle. Draw pipes between pairs of the same color. Lines move only up, down, left, or right. They cannot cross. You clear a stage only when every cell is filled—so linking pairs is not enough. You have to plan the routes. Easy to learn, harder as colors and grid size grow. The app includes 55 original stages from 5×5 to 8×8, plus a daily 3–5 color challenge generated on your device. No account.
