Challenge Games creates short, online games for both serious and casual gamers that are exciting and easy to play. These games are browser-based and can be played from any computer. Most of the games are multiplayer, and take only 3-10 minutes per game. They provide instant entertainment, unlike other popular games such as World of Warcraft or Lord of the Rings. All the games developed by Challenge are free. The first game the company released was Duels, which is a fantasy game with level advancement, development of the characters, collectability and trading. Duels was the first game available on Facebook as an application. Players can pay a small subscription fee and sign up for VIP membership or can play the free version of the game. The company’s second game, Baseball Boss, is a combination of fantasy sports and baseball card collecting. Both games are designed with the aim of making players trade virtual goods like better swords or better equipment to improve their game. Such collectibles can be purchased with real currency. Although free, the games generate revenue by selling virtual goods to users.
