My dad plays a lot of Spider Solitaire on his computer. He told me he noticed he solved it very often in $299$ moves.
I'm not a mathematician, but I think someone must have thought of the mathematics behind this game. In particular, I'm curious if anyone calculated the most probable score and if it's close to $299$.
Unlike normal Solitaire, the Microsoft version has $104$ cards for the advanced level, which is what I'm referring to.
