The Town Game Room B is a place in Mario Party Advance. It is found in the Town Area of Shroom City. This place is a companion to the previous game room (Town Game Room A).
When the player enters this place, an Amp is found sitting at an arcade machine. The Amp mentions he is having trouble beating a minigame. If the player helps the Amp with finishing the minigame by taking the quest Losing Streak and completing it, the player keeps the minigame (Match 'em).
