About This Demo

Uga Buga! is a social deduction game set in the Stone Age for up to 12 players, where you try to uncover the bluffers hiding within your tribe.


  • Each player is assigned a role by the system: either Bluff or Fan.
    A secret word chosen at the start of the match is distributed to the players along with their roles.

  • Players take turns giving a clue related to the secret word. You must choose your words carefully during this process. Bluff players shouldn't be able to figure out the secret word too easily, while Fan players shouldn't grow suspicious of you.
    If you suspect something, you can call a vote and share it with the other tribe members!

  • The player who receives the most votes is eliminated and sent to the cage!

  • If you are in the Bluff role, you have one more chance to win!
  • If you can guess the secret word correctly, being thrown into the cage doesn't matter at all. You can win the game directly.

  • You can customize your character however you like with the available options!
