Balloon Brothers is a two-player Tetris-type arcade game released by East Technology in 1992. Different colored balloons in different shapes float to the top (instead of falling). Completing a full row across will make that row disappear.

While it can be hard to find a working machine in a museum today, since arcade machines were replaced with new games continually at the time, one can play Balloon Brothers via emulators MAME since version 0.37b9 or FB Alpha since version 0.2.96.83
