But for Density mode, the overall number of mines is limited to a certain amount, isn't it?
I mean not the theoretical maximum amount, the field size, but a lower one.
IIRC, e.g. for the maximum size, it was something around 668, is that correct?
(I don't have to original minesweeper anymore.)
I only have the Minesweeper Clone tseug suggested, and there's no limitation (e.g. you can set 63 mines for beginner).
Being able to do that, it's easily possible to get x * y - 1 for any size because the first click will never be a mine.
