We are launching a skill game website, where customers compete in different games against each other. They pay a buy in amount + fee into a price pool. When a game is finished winners will be paid out through some payout scheme, for example:
Place 50 %, [url removed, login to view] 30% [url removed, login to view] 20 % of the price pool
To handle customer balances, transactions and price pool we are planning a database application on a secure, seperate server. The main web site shall communicate with this database through some kind of interface. Further, on the database server, information about past and running games will be stored (Participants, buy in, collected fee,….)
If a game is finished, the ranking of the participants shall be delivered to the server, which will increase the winners balance according to payout scheme.
So you will create only the database application, preferably using PHP and MySQL.
For an more detailed overview of the expected functionality, please see the attached document.
