Let me see if you can help me understand something. Yesterday I played a few hands, but only a few, about 10 or so, and I'm sure I got a cashback, because what I had left in my account was a round number and now there are more.
Is it maybe what was being talked about in the previous page?
Yes, That's a reward from the hourly wager and hourly biggest win contest because you can easily win few satoshi if you made few bets before the hourly countdown end. This is what they are discussing on the above topic and the bug on the rewards that carry over on the next round bet.
Sometimes bets made before the clock ends both counted on the current round and next round for games such as live casino that typically took few minutes to conclude the winner. I experience this already while playing live blackjack while the result was release few seconds before the countdown end. I notice that my winning entry on previous round is same to the next round that's visible on leaderboard and chatbox announcement of winner.
