Update: Club Nintendo now lets you buy download games with coins.

Original story:

Fed up of those Club Nintendo coins going to waste? A major update is on the way that will let you turn them into games.

You'll be able to use your coins to purchase download games for the Wii or 3DS using either system's download voucher redeem ability. For example, Fluidity is 150 coins, whereas 3D Classics: Xevious is just 100.

The site is down for maintenance at the moment but when it returns you can expect a whole world of coin-related japery.
