Is every game of Spider Solitaire winnable?

No. Not every Spider Solitaire deal can be won, no matter how well you play. The shuffle decides the starting layout, and some layouts are genuinely dead from the first card. Winnability depends on both the deal and your skill. A group of cards moves as a unit only when it forms a same-suit descending run, so a tangled deal can lock up with no legal way forward. On this site, undo is unlimited and free, with no score penalty. That lets you back out of mistakes and try another line, but it cannot rescue a deal that was never winnable. Knowing when to abandon a dead game and start fresh is a real skill. Try 1-suit to win more often.
