They describe the runs of filled cells in that row or column, in order, with at least one gap between runs. "3 1" means a run of three, then a gap, then a single cell.
No. Every puzzle is verified solvable by pure deduction before it ships. If a picture would force trial and error, it is thrown away rather than given to you.
Marking a cell you have proven empty. On a fifteen or twenty wide grid it is how you keep track of what you have already ruled out.
The mark is decided by the first cell you touch, so a drag never changes mode halfway. Touch an empty cell to fill, or a filled one to clear.
Nothing forced. You are offered a way to keep going. Losing twenty minutes of work to a counter is not our idea of a puzzle.
