Lot of people? Are you blind? Noone is playing at your pathetic SCAM site, made by some crippled programmer. Except os yourself, ofcourse, and maby your partner-in-crime - just to make some visible activity.
There even NO logs of deposits and withdrawals made by player. How someone could check his/her transaction history? This option is realized on EVERY normal bitcoin playing site, even poor and nearly unknown (but not SO MUCH as your site, though). You can simply check out this list, for example: https://bitcointalk.org/index.php?topic=1417922.0
Of coure, on your site - it's not a priority, because there is SO MUCH another issues, that should be resolved even BEFORE opening.
However, the main problem is not how your site looks like or even how it works like...
The main problem - is you are SCAMMER, who do not response for your own words. You do not have any "instant withdrawals", you simply delete account with balance on it if someone win and want to withdraw.
The additional proove of how raw and stupid you are - this screenshot, where my account is marked in the list of winners as "[unknown]".
This is perfect illustration of what SCAM-method you are using. Just delete account and noone ever know, right?
