One board. Every color. Find your flow.

About this game

Connect matching colors with smooth, glowing paths in 24 handcrafted puzzles. Drag through neighboring cells without crossing another color, retrace a line to reshape it, and grow from a gentle 4×4 board to intricate 8×8 challenges. From level 13, every cell must be covered. Relax with unlimited free Undo and Reset, collect stars, and improve your personal move records—there is no timer or move limit.

How to play

  • Mouse or touch: hold a colored dot and drag through orthogonally adjacent cells to its match. Retrace to erase; grab a dot or your own line to redraw. Use the Undo and Reset buttons (keyboard: U / R). Open the level map with the grid button; press Enter or tap Next Level after a clear. The music button toggles all sound.
