The best submission, as voted by a PlayStation judging panel, will be rewarded with a month-long internship at Swedish studio Tarsier (creators of the handheld title).
Games will be judged on gameplay, originality, and commercial appeal, PlayStation said. The winner will eventually help work on official DLC for the game.

"Gaming is an exciting and fast-growing industry but it can be tricky to get your foot in the door," said the game's product manager Elliott Linger.
"This internship offers a whole month's experience at a great studio, all for creating an awesome minigame. We're expecting hundreds of entries and can't wait to see what players of LittleBigPlanet Vita come up with."
