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. The version from Sun Microsystems from 1989 defines the following rules in the manual: 10 points for each initially face down card that gets turned over 15 additional points for each column where all the face-down cards have been turned over (even if you don't manage to get a space) 2 points for each card that is sitting atop the next higher card of the same suit 50 points for each completed suit removed from the tableau (in which case you do not also score for the 12 cards sitting atop next higher cards).
