Previously, it's been called Wizard Extreme, Die Seiben
Siegel, and ZIng! It is the
overall #160th ranked Family Game (out of over 5000) on BoardGameGeek.com. Tens of thousands of copies have been sold and it's still selling strong in Germany and many other countries. But it has been out of print in the US for over 10
years now and there is a whole generation of new game players that have never heard of this game--the one we now call Sluff Off that has shed its
old skin and looks very different in its new one, though it plays the same.
Gameplay follows the standard trick-taking formula: The cards are numbered 1-15 in five different suits, blue is always trump. If someone leads a color, you must follow suit if you can; otherwise,
you can "sluff off" a card or trump the trick. It's an exact-bidding game, but you predict your tricks by taking colored tokens. For each trick that you win, you toss a token back. If you take a
trick in a color for which you didn't have a token, then you must take a black chip (worth -3 points). If you have any colored tokens left at the end of the round, they're worth -2 points. If you
have any white tokens left at the end of the round (wildcards that you get when someone takes a colored token away from you during bidding), they're worth -4 points. There's also the sluffer
(previously called the saboteur) whose role is to feed unwanted tricks to other players. Instead of bidding tricks he takes 4 black tokens. When players take tricks they didn't predict they take
black tokens from the sluffer. If the sluffer can feed enough of the black tokens to enough players, he can zero out his score for that round. He gets -1 point for every black chip he has left at the
end of the round, up to a maximum of zero.
