Is there a problem with balances? I used to have about 35k satoshis just a few hours ago, now I logged in and poof, only 4k left?!?!? Checked my stats, no payments are sent or games played so that rules out my account getting hacked. What could have happened???
If you can't see any suspicious roll on your betting history. You can check on your email for an unknown login attempt. My freebitcoin account too was attempted to login of unknown user and try to change email multiple times recently. You can request to support for the list of your IP login to verify there is a hacker that accessing your account.

From the screenshot you posted they have already successfully hacked your account. You need to be logged in to turn on 2fa to change the email. The most likely is that you used the same password on another site and that site's database has been leaked. Alternatively, you may have malware on your device and they were able to hijack your last session by stealing your cookies. Either way, you should log into your account and change the password to stop the emails coming through.
