About Jibber Jabble, from BoardGameGeek:
Jibber Jabble is a game of teamwork, sabotage, and spelling. It consists of several rounds in which you work together to get one person, the Jibber, to guess a secret word based on three clue words provided by the other players. The other players cannot communicate with each other to decide what the clue words will be. Instead, they must spell out the clue words one letter at a time. Starting with the player to the left of the Jibber, each player will use their turn to either give a letter, end a word, or play a power card. A round ends when the Jibber has either successfully or unsuccessfully guessed the secret word.
There are two main ways to play Jibber Jabble. Party Mode and Sabotage Mode. Party Mode is ideal for large groups or when you want simplistic, cooperative, and “friendly” gameplay. There's no point system, you just play as long as you want. Sabotage Mode adds some spice to the game and is better suited for 4 - 9 players who are ok with being pitted against each other. We recommend starting with Party Mode to get used to the mechanics of the game, and then trying out Sabotage Mode if you're ready for something more.
If playing in Sabotage Mode, players are either Jabblers or Jesters. Jabblers are trying to give helpful clue words - Jesters are trying to covertly sabotage the clue words, either by giving unhelpful letters or by using a power card to disrupt play order.
