Just tried your site OP, claimed a faucet and i got this

I was played on 49.5% win chance or 2x multiplier, my first bet won, but why in my second bet,  it showed -0.00002001 ? From where 1 satoshi come? i was bet 1000 satoshis and won, then i bet 2000 satoshis.

1000 satoshis in an hour is too crazy OP

Edit: Where can i check about your provably fair in each of my bet? I can't click anything from my bets earlier, bet ID, etc etc.
