And sorry about the problem with roulette. I only use Bitcoin every single casino,,, so cannot offer help there. Why not exchange your crypto for BTC to gamble?
Yeah there's seems some visual bug too on website when using mobile phone. I experience glitches whenever I click multiple games in short interval. The developer is always doing regular maintenance every month to optimize all bugs. We just need to keep posting here or in the chatbox all the issue we encounter while playing on the casino to help them improve it quickly.
I don't like to convert my altcoins to Bitcoin and use it to play because exchange has a flat rate of 0.0005
BTC on the withdrawal and this a huge amount for just depositing for gambling purposes. I'm still happy playing despite only evolution gaming games and in-house games are what I can play.

I think that is because the UI needs to 'finish' or 'settle' all of the animations first. I get the same thing if I want to like place a new bet/rebet or do a new action, some bets do not settle until you go back to the previous game and allow the animation to finish (even the part where your wins are credited and the numbers in your balance all run up fast like speedometer).
Try using 2-layer DEX like 1inch to swap, very low fees on Polygon to BTC, then go sell it p2p

Troublesome at first but worth it!
It's interesting, but no matter how many times I tried, I still couldn't get to the blackjack website.fun to register, even through vpn I tried a bunch of location options and always get the message: "
We are very sorry but it appears that your IP is from United States and due to Gambling Regulations the domain blackjack.fun does not accept gambling from your country"

Then your VPN is leaking your real site. You have to use a good VPN with software and no DNS leak
