Town Game Room A
From the Super Mario Wiki
The Town Game Room A is a place in Mario Party Advance. It is found in the Town Area of Shroom City. This place is actually a companion to a second game room that is found right next to it (Town Game Room B).
When the player enters this place, a Monty Mole is found sitting at an arcade machine. The Monty Mole mentions that he needs help playing one of the minigames. If the player takes the quest Winners Keepers and completes it, the player gets to keep the minigame (Scratch 'Em).
