The sequel to the party game phenomenon The Jackbox Party Pack, featuring FIVE fresh, rib-tickling party games! Games include:
Fibbage 2 (2-8 players)
The runaway hit bluffing game with over 500 brand-new questions, more than 2x the original! Plus new features, like the deFIBrillator!
Earwax (3-8 players)
The hear-larious sound-effects game that will leave you up to your ears in laughter!
Cow moo? Huge explosion? Or tiny fart? Which to choose?
Bidiots (3-6 players)
The absurd art auction game where you draw right there on your phone or tablet. Outbid your opponents for weird art pieces – drawn by players themselves – and win this strangely competitive auction game! Don’t be a bidiot!
Quiplash XL (3-8 players)
The say-anything, gut-busting Quiplash XL, which includes everything in Quiplash, Quip Pack 1, AND over 100 brand-new prompts!
Bomb Corp. (1-4 players)
The bomb-defusing nailbiter of a party game! As interns at Bomb Corp., you must defuse random bombs in the office in order to keep your jobs. You’ll probably die, but it’ll be good work experience!
