To help spur community growth and activity, there are contests held on occasion. These contests are usually related to something around game development, but can also be modelling, or just about anything within reason. To access the active contest, clicking the 'Contest' button on the navigation bar will take you to the active contest thread. Past and current community contests can be found in the contest board.
Prizes on offer vary depending on the size of the contest, and the active forum supporters.
