The blurb on the website says:
"Nokia Publishing invites you to take part in the Mobile Games innovation Challenge for developers.The rules are pretty simple.
"We are looking for the best, most groundbreaking concepts from the brightest and most creative minds in our industry. This is your chance to shock the mobile gaming world and possibly have your game concept published by Nokia."
All you have to do is submit a mobile gaming concept that uses the features and functionality of any Nokia N-Gage, Java or Symbian-based Series 40 or S60 device.
The three most innovative game concepts will be offered pre-production contracts from Nokia, with the winner awarded 40,000, together with a second place prize of 20,000 and a third prize of 10,000 which are designed to enable the winners to further develop their concepts.
The submission form is available online and provides for the uploading of documents, graphics and videos, but not demo code.
The deadline is August 20th with the winners being announced during the Nokia Game Summit on October 29th.
