MarblesMarbles is running a game design competition they’re calling, “Who’s Got Game?“. The company is looking for “unique” “pattern games” for 1-2 adult players.

While the deadline is short—this Friday, August 1st—only photos and a description are required (prototypes are optional). The grand prize is also pretty nice—$2,000, an appearance on the National Geographic Channel’s Brain Games, production and distribution by Marbles, and a 5 percent royalty on retail sales.

Other than the winning entry, entrants retain rights to their submissions.
