This game plays almost exactly like UNO (it is actually closer to Crazy Eights). Even though the action cards differ a bit from those of UNO, they're strongly based on them. The game also includes one or more jokers. With a joker you may play an action of your choice. Another difference is that this game lacks the scoring mechanism which is included in UNO. Differences between versions: 1:Pirates of the Caribbean: - Has larger cards - Drawn images are shown on the cards - Includes only one joker - Shows only UNO-like symbols 2:Pirates of the Caribbean - Dead Man's Chest: - Has normal sized cards - Photos of the movie are shown on the cards - Includes three jokers - Shows playing card symbols besides UNO-like symbols 3:Pirates of the Caribbean - At World's End: - Has normal sized cards - Photos of the movie are shown on the cards - Includes two jokers - Shows playing card symbols besides UNO-like symbols Sets 2 and 3 are identical, except for the Joker count (3 vs. 2). Set 1 differs significantly in card distribution: - numbers run from dedicated 1 thru 8 (instead of suited A/1..10) - special cards are fewer, there are only 2 of each type (instead of 4, or 2 for +2/+4)
