Is it haram to sell virtual points in video games for betting?

As a game developer, I've been offered a job involving a video game where players can purchase virtual points with real money, which cannot be exchanged for real money. The points are only used for playing games online, and free points are also given to all players daily. The game allows two players to bet their points, and the winner receives all the points/coins. I believe this is a form of gambling, but I'm uncertain.
