Nintendo's efforts to tempt gamers into an eShop purchase of New Super Mario Bros. 2 instead of the boxed alternative is now kicking in outside of Japan. We've already reported on retail download incentives in Japan, but Nintendo of America is joining in with its own offer, and like Mario's new adventure it's all about the coins.

As announced on the Club Nintendo website, if you buy the title from the 3DS eShop and complete the registration survey within four weeks you'll receive 100 coins instead of the standard 50. The offer applies until 20th September and, for those that haven't done so, you need to link your 3DS account with the Club Nintendo equivalent before buying the game. As for Europe, we're yet to hear about any equivalent offers at the time of writing, but we'll keep an eye out for updates.

There's no Virtual Console freebie like in Japan, but will 50 extra Club Nintendo coins tempt you into a digital download?
