Casual Collision was a site designed by Max Stein, a web designer, game developer, and business person. The original design is based off a rough draft mock-up designed by mochiads user agestone you can see this mock-up here. Casual Collision was created to give game makers new ways to monetize their games, while users of the site reap the benefits of the better developer/portal relationship. What this means is developers can earn money for adding our score api to their game, uploading their game, or referring new users to Casual Collision. This is good for the users because it encourages developers to add content, especially content with high scores which make games on our site fun and competitive. Our philosophy is that we can create a fun safe place for users to play while keeping the developers who make the games in mind as well.
