How is Spider Solitaire scored?

On this site you start every game with 500 points. Each move you make costs 1 point, and each completed 13-card suit run (King down to Ace, same suit) sent to the foundation adds 100 points. Finish all 8 runs and those runs alone give you 800 points. So your final score is 500, minus your total moves, plus 100 for each run cleared. Undo simply reverses a move and its cost, with no extra penalty. The math rewards efficiency: the fewer moves you use, the more of your starting 500 you keep. A tidy game can finish net positive on moves and push past 1,000. Try it on the Daily Challenge and watch your score build.
