+> Not a trivia buff? It doesn't matter! In Wits & Wagers, each player writes a guess to a question such as “In what year did the bikini swimsuit makes its first appearance?” or “How many feet wide is an NFL football field?” and places it face-up on the betting mat. Think you know the answer? Bet on your guess. Think you know who the experts are? Bet on their guess. The closest answer — without going over — pays out according to the odds on the betting mat. Strike it big and you'll be cheering like you just hit the jackpot! Wits & Wagers is a trivia game that lets you bet on anyone's answer. So you can win by making educated guesses, by playing the odds, or by knowing the interests of your friends. It can be taught in 2 minutes, played in 25 minutes, and accommodates up to 20 people in teams.

 > Just One is a cooperative party game in which you play together to discover as many mystery words as possible. Find the best clue to help your teammate. Be unique, as all identical clues will be cancelled! A complete game is played over 13 cards. The goal is to get a score as close to 13 as possible. In case of a right answer, the players score 1 point. In case of wrong answer, they lose the current card as well as the top card of the deck. Thus losing 2 points. In case of lack of answer, the players only lose the current card, and therefore only 1 point. You have the choice – make the difference!
