Extreme 500 is a classic game of 500, developed by James Swiney. It has a fresh, elegant, and simplistic design that adds a modern touch to this traditional game. The game is available on the iPhone platform and is licensed as a full version game.

One of the best features of Extreme 500 is the choice of playing either the traditional 4 player partnered 500 or the cutthroat 3 player solo 500. The game also provides challenging and intelligent AI opponents to play with or against. Additionally, players can choose from three different scoring systems and customize their deck by selecting the number of cards they want to play with.
