The Jackbox Party Pack 4 is a multi-device multiplayer party game collection developed and published digitally by Jackbox for the Xbox One, PlayStation 4, Nintendo Switch, Amazon Fire TV, Apple TV, Android TV, iOS devices, PC, Mac, and Linux on October 17-19, 2017.
It is the sequel to the Jackbox Party Pack 3 (and the fourth in the annual series of the same name). The games included are:
- Fibbage 3 (2-8 players) - The third installment of the Fibbage series, with new potential prompts and a new art style (reminiscent of 1960s & 1970s pop culture). Players attempt to bluff other players by making up plausible fake answers to trivia questions (while attempting to pick the correct answer themselves). This version includes a bonus game mode, titled "Fibbage: Enough About You", where players answer a question about them honestly and other players play that question in the usual Fibbage format.
- Survive the Internet (3-8 players) - Stylized on 1990s & 2000s Internet culture. After answering their randomly-chosen question with their opinion, each player then takes another random player's opinion out of context (with no knowledge of the original question) and forms a topic for which the opinion would make an awkward or offensive comment on. Players then vote for the most ridiculous pair.
- Monster Seeking Monster (3-7 players) - Players attempt to get the most "hearts" by successfully going out on dates with other players. On each round, each player sends up to four messages to other players before selecting one other player they would date. When two players both select each-other, they earn a heart. Secretly, every player is a monster with hidden powers that grant unique scoring bonuses and effects.
- Bracketeering (3-16 players) - Players give answers to a single random prompt, all of which is then pitted against eachother in a single-elimination tournament. On each tournament matchup, all players vote for their favorite answer (and, on ties, come down to "button mashing"). Players earn points for both winning pre-bracket prediction bets and for having the winning answer. Later rounds change the name of the bracket (without accommodating for the answers).
- Civic Doodle (3-8 players) - Similar to the series's other drawing-based games (namely Drawful, Bidiots, and Tee K.O.). Players take turns contributing on a mural-in-progress. Each participating player draws on top of the most popular doodle, while participating in a voting war with the other participating players. The winning drawing remains for the next matchup until the round expires.
