BS Button Game Expansion Pack offers a new spin on shedding games like Doubt, Cheat, and Bullshit. It includes a sound button, True Blue, which flashes bright blue and calls bullshit 70 different ways, 52 standard playing cards with original art, and a new wild card, the activist.
The addition of the activist card allows stand alone play with three to six players. BS Button Game Expansion Pack can also be combined with BS Button Game to accommodate up to twelve players.
The activist is wild and can be played to call a rank out of sequence and force an opponent to discard that card or to bluff. Players have the option of hitting the BS Button anytime they suspect a bluff.
The first player who discards every card while avoiding a valid call of bullshit wins.
