Go to Nintendo's eShop to purchase downloadable packs for coin rush mode. They range from the fierce nerve-rack pack, Gold Mushroom packs, to fierce coin challenge packs. They will definitely help you get to the 1,000,000 mark faster and get to make that happen. They do cost $2.50 each, but they are worth the money. Activate Spotpass and access the internet through the Wi-Fi connection of the 3DS. Once shop is available, you can buy packs through the 3DS pre-paid cards or credit cards. They only have 3 levels each, but will help you zone in onto your skills, and are worth the effort. Can you score 10,000 coins in coin rush mode? 20,000, or even 30,000 coins in one round?
