Yayy another achievement you can get with bots!
The more bots the better but I would limit it to you plus 2 or 3!
Get into any minigame, wait for some of the bots to snag some coins and than go up to them and press B. They also may attack you as well so be prepared!
Bonus : You don't actually have to steal all 10 coins in any ONE game you can do it over multiple games not just mini games.
