Hello wagabet I received the 10K satoshi from you. and I tried couple of game I tried all to be honest  It was fun until I want to withdraw it and the fee was 0.0015 I mean this hella expensive in my opinion is that possible you can lower the transaction fee or you can add desire fee for user to choose.

And lastly like other player I think you should add other game like crash, plinko or blakjack and add chat Features it would be fun in my opinion
