Fill every square with a diagonal so each clue counts true and no loop forms
- Filled
- –
- Tap cycle
- \ first
Click a square, or select it and press Enter, to draw \; again for /, then clear. Right-click, Ctrl-click or Space goes the other way: /, then \, then clear. The \ and / keys draw that diagonal and Backspace clears it. On a touch screen, \ first and / first choose which way a tap cycles. Ctrl or ⌘ Z undoes; Ctrl or ⌘ Shift Z redoes.

How to play
Fill every square with a diagonal line, either \ or /.
A number on a grid point says how many diagonals touch that point. Points without a number can have any count. The diagonals may never join up into a closed loop.
Diagonals on a loop turn red with a dashed pattern, and a clue with too many diagonals touching it, or too many squares round it turning away, turns red with a dashed ring. Undo and Redo follow your history; a new move after Undo replaces the old branch. Restart clears the board and can be undone. Solve reveals the answer; a puzzle finished with Solve does not count as solved.
