Coin Runners MK7

As seen in Mario Kart 7.

Coin Runners (Coin Battle in the European version of Mario Kart 7) is a Battle Mode introduced in the game Mario Kart Wii.

In this mode, players are split into two teams with a three-minute time limit, and coins are scattered all over the battleground. Players can pick up coins by running over them. More coins will fall from the sky periodically until a certain amount is on the field, then they will stop falling (unless coins go out of bounds, in which case they will reappear at a random spot on the field).

Getting hit by a Banana Peel or a Fake Item Box causes the player to lose 3 coins, while getting hit by any kind of shell or run over by a Mega Mushroom causes the player to lose half of their coins (with a minimum of 3). Getting hit by a Star or a Mushroom causes the rammer to steal 3 coins.

At the end, whichever team has the most coins wins the round.

The mode returns in Mario Kart 7, but with a two-minute time limit and it can be played by themselves with a maximum of ten coins.

This mode returns again in Mario Kart 8 Deluxe with a Time limit ranging from 1-5 minutes (it's your choice) and you can carry as much coins as you like once again just like in Mario Kart Wii.
