Shamelessly reblogging from Joe Healy over at DevFish:

GOT XNA?
WRITING AN WINDOWS PHONE GAME?
WANT A SHOT AT THOUSANDS OF DOLLARS?

Here’s the short version. Over 14? Write a cool Windows Phone Game and submit it to the Dream.Build.Play site. You could win up to $20,000. Yep, that’s it. In a nutshell. So on to the long-winded stuff.

Windows Phone the prizes are $20k, $10k, $5k, and $2500 respectively. The top 20 finalists will also get Phones. Want some inspiration, check out last year’s XBOX winners at https://www.dreambuildplay.com/main/winners.aspx . Obviously the competition is going to be tough. Make something good. And if you publish it, let me know. I’m always looking to brag about our phone devs!
