Row 2 6 3 1 5 4. 1 of 5 clues satisfied. 6 swaps left. Cursor on cell 1, holding 2. Clue 1: 4 and 2 are next to each other — not satisfied.
4 clues are still broken. Drop any one clue and up to 8 arrangements would fit, so none of them is spare — a steady board.
← → move along the row · ↑ ↓ step through the clues, which marks the two cells it names · Enter picks a digit up, then Enter on another cell swaps them · Esc puts it back for free. Click the board first, or press Tab to focus it.
