About the game

One marked cell, one unbroken line, and a board that has to be filled completely. You can't step on a cell twice and diagonal moves are out, so every turn matters. Boards start small and grow as you move through 41 chapters, each with its own color theme.

Easy levels sit between hard ones, and a boss level closes every chapter. Double blocks, bridges and arrows join in along the way. A daily puzzle with a reward opens each day, and coins unlock themes with their own sounds. There are no timers and no game over.

How to play

• Press on the pulsing start cell and drag up, down, left or right without lifting your finger. On a computer, step with the arrow keys or WASD.
• Stuck? Drag the line back, tap any cell on it to continue from there, or use Z or Backspace to undo. R restarts, H shows a hint.
• Ring blocks get crossed twice. On a bridge you cross once vertically and once horizontally, with no turning. An arrow only lets you pass in its direction.
