what the hell? the part of your site that describes your "md5 honesty control" is total gibberish. Let's say I played the roulette at your site and it rolled the number 5. explain how I'm supposed to verify that this result was fair and couldn't have been influenced by my bet. and no, your "MD5 FAIR-PLAY GAME CODE GENERATOR" (which doesn't even give valid MD5 digests) doesn't cut it.
Unfortuanatelly, we dont have strictly caled "provable fair", MD5 is used only for non-intervention in random generator. There is impossible to do "provable fair" in slot machines. You can know as it not depends at your bet as you won 1 PV by betting 0.2 in "Lucky Star" slot machine.
