How to play
- Goal
- Place A, B and C once in every row and column so each edge clue sees its letter first.
- How it ends
- A chart is complete when all letters and visible edge clues agree; there is no loss.
- Record
- The fastest first solve of each chart is kept locally and on the public board.
- Place A, B and C once in each row and column; leave two gaps. An edge clue names the first letter visible from that side. Gaps do not block the view. In the worked example, putting B in the unknown first square makes the left B clue true.
- Choose A, B, C or the optional gap mark, then tap a square. Tap the same mark again to clear it. A glowing clue means its completed line agrees; a red clue means that line disagrees. A repeated letter is a correctable warning.
- Undo restores the last mark. Restart clears the chart while its first clock keeps running. Place the fifteen letters correctly to finish automatically; unmarked gaps are allowed. Replays are untimed practice and keep the original first time.
