Backgammon Game

In this project i want to Backgammon game for a website. Game will be mutiplayer so 2 people will play each other on my website. i have other games too in my website so i have a point system. user's points are kept in a database so they use this points replay games and for to win prizes in our lottery system. Backgammon is straight forward game so no need to describe how it plays. but important parts are 1- will be online game and users **play against each other NOT against computer. **2- for to play users need to spend points. so points will kept in database 3- for example game requires 50 points to play and when two user start to play they pay 50 points each so totally 50+50=100 when one user win to game he/she will take this 100 points. Maybe we can add rising bids option so if users have more points they may can increase to jackpot. My website will coded in php so database is mysql database. Game can be coded in Java or Flash its totally up to coder. if you have more questions you are free to ask. thanks for your interest huseyin kecoglu
