Coin-op Bop
From the Super Mario Wiki
Coin-op Bop is a 1 vs 3 mini-game in Mario Party 7. Each player stands in front of a slot-like machine pressing buttons to get coins. The three people on the right have to press one button per person, while the solo player on the left has to press 5 buttons alone.
If a player presses an incorrect button, a Bob-omb will fall down and explode, causing them to be stunned for a few seconds. Each series of buttons will earn the team three coins; in the end, both teams will collect all of the coins they earned.
