Flow Puzzle
Click a dot, then click each cell to build a path toward its matching color — click the matching dot to finish. Paths can't cross each other or reuse a cell.
This style of connect-the-dots puzzle became popular through mobile apps built on one simple constraint: every cell on the board has to be filled by exactly one path, and no two paths can cross. That single rule is what turns a handful of colored dots into a genuine spatial-planning problem instead of a straight line-drawing exercise.
The reliable solving order: connect the pairs sitting in corners or along an edge first, since a dot boxed in by the border has far fewer possible routes out. Save the pairs in the open middle of the board for last — they're the most flexible, so they should bend around whatever the edge pairs already committed to, not the other way around.
Every layout here starts from a real path already drawn on the grid for each color, and only the two endpoints are shown to you — so whatever you're handed always has at least the original route as a working solution, even if you end up finding a different one.
Click one dot, then click each cell in a path toward its matching dot — click the matching dot to finish. Paths cannot cross each other.
Click the cell you just added to undo one step, or click the starting dot again to cancel that color and start over.
Easy uses a smaller grid with 3 colors. Medium and Hard add more colors and a bigger grid, so paths have to work around each other to fit.
