How to play
- Shade some cells. Shaded cells never touch side to side, and clue cells are never shaded.
- An arrow clue counts the shaded cells in its direction, all the way to the edge.
- Draw one loop through every cell that is not shaded and not a clue. It moves between cells that share a side and never crosses itself.
- Tap a cell to shade it, again for a dot that marks a loop cell, again to clear. Drag from cell to cell to draw the loop, or over a line to erase it. Tap the border between two cells to cycle line, cross and empty.
Keyboard: arrows to move, Shift+arrow to draw or erase a line, Alt+arrow to cross a side, space to cycle, s shade, d dot, h hint, Ctrl+Z undo, Ctrl+Shift+Z redo.
