Twitter Inc.’s founders still haven’t decided how to cash in on their popular Internet messaging service, but this may not prevent a gold rush among opportunistic outsiders. Lolplaying, the maker of a new role-playing game on Twitter called 140 Mafia, is trying to explore Twitter’s moneymaking potential with Super Rewards, a “virtual currency” service that has already been reaping revenue from various forms of online recreation.

Super Rewards gives players of online and mobile games ways to gain the upper hand against their opponents. The price: A fee or a willingness to accept offers from advertisers. It’s already proven to be a lucrative model at Facebook and MySpace, as well as on the iPhone. Super Rewards co-founder Jason Bailey is confident that it will now pay off on Twitter as 140 Mafia attracts more players. Most people pay Super Rewards about $10 for a competitive advantage, but some game players have forked over thousands of dollars.
