Sardines

It's eat-or-be-eaten in this twist on Go Fish. Cast your line, reel in your catch, but beware -- reel in a sardine, and you'll be sorry! Outbluff your opponents to score the biggest catch! In this twist on a childhood classic, you'll play Go Fish as usual. However, when giving cards to other players, you do so face-down. They must then decide whether you're being honest or bluffing -- a decision that will end with either their reward or ruin. —description from the designer
