Smash bosses. With your friends. Using only one button.

Legend speaks about warriors known as the Brawlers, who defend the kingdom from monsters that come to destroy and wreak havoc. Each brawler is a gifted tactician and fighter, and each one can finish off foes using only a single finger.


BBBB is an online multiplayer game with support for 2-4 players. 4 players is recommended. Players must take turns pressing one button in order to complete a pattern. Each completed pattern will damage the boss. Time is ticking down, so players must be quick in order to take down all 3 bosses.

How to play

BBBB only uses a single button to play the game (the default is spacebar). You must press the button when it is your turn to press. Sometimes, you will have to press and hold the button before releasing.

Player 2 must press twice, then Player 3 must press twice.

Player 2 must hold while Player 3 presses twice.

Hosting a server

If you want to play over the internet with your friends you will need to port forward. The port for BBBB is 22122 (UDP).

Instructions for port forwarding can be found all over the internet.

If you are connecting to someone else's server, you do not need to port forward.

Played a few games of it already with everywhere between a party of 2 and 4. If you're like me and you don't bother to read the controls with your friends, you will stumble into a frantically fast-paced rhythm game where the spacebar becomes your best friend.

Play this game if you're looking for an exciting and engaging time with strangers or your best friends!
