This yields a maximum score of 990. If you win the game with 4 or more completed suits still in the tableau, add 2 points for each suit after the first three. Thus winning with all eight suits still in the tableau yields a score of 1000. In the Windows versions of Spider Solitaire, the scoring is calculated with a starting score of 500. One point is subtracted for each move (including any use of an undo); 100 points are added for each suit completed. This allows for a theoretical maximum score of 1254.
