If you're planning on unlocking everything in Mario Kart 8 Deluxe, then you're going to need a lot of coins. 10,000 to be exact.
Getting there usually takes a long time, so you're probably tired of waiting. To use this trick, simply do the following:
- On the main menu select Multiplayer 2p.
- Choose VS Race.
- Select any two characters and kart configurations.
- Select the Moo Moo Meadows track.
- Make sure Smart Steering and Auto Acceleration are enabled for both players.
Good luck!
