A Slot Coin is a purple coin that appears in Mario Hoops 3-on-3. It is exclusive to the Jr. Street stage, where players can collect them when ? Panels turn purple. When players score a point while the purple coin is acquired, it initiates a slot machine, where the scoring team can obtain more points than usual, take points away from that team, or have no effect.
