Draw a single continuous line that passes through every dot on the grid exactly once.
Rules
Tap a dot to start, then swipe or tap adjacent dots to extend your path. You can only move horizontally or vertically (no diagonals). Each dot can only be visited once.
Blocked Cells
Some levels have blocked cells (shown as dark squares) that cannot be visited. Plan your path around them.
Tips
Use Undo to backtrack, or Clear to start over. Solve quickly for time bonus points. Corners and edges are good starting points!
