We've just had an email from Francois over at Empty Clip Studios, asking us to let you know about an upcoming competition for North American readers only to win one of 100 copies of Groovin' Blocks, the company's rather enjoyable WiiWare puzzler.

All you need to do to be in with a chance of winning is send your 16-digit Wii code to free@emptyclipstudios.com. Make sure you mention that Nintendo Life sent you!

You can check on the promotion's status and see if there are still copies to be won by heading over to the giveaway website. Want to know if it's worth buying? Check out our Groovin' Blocks review to find out what we think.

If you're unsure how to find out your Wii number, here's a handy video from the page to help you out. Good luck, and remember, this is for North America only.
