You can keep track of your transactions and game play in Transactions, located under My Account tool:
Transactions page is divided into three different parts for you to easily navigate and get the information that you want in the easiest way.
Under these sections, you should be able to see your history for up to 3 months back. If you need to see older period, no worries, choose Another period from drop-down menu of Transaction Period (keep in mind that specified date range must be no more than 3 month):
Here you will find all your transactions made for specified period (including deposits, withdrawals and game play).
