I checked the site and tried to play the demo, it's nice that you have that feature.
Welcome to the community, though I'm not really good with Blackjack but I love how simple the site is, it's like I'm playing on my deskstop computer offline as there's no lag in your game.
If you are not good at one game, you can be at another. I can share a couple of where you can try your like in playing a dice game, wheel of fortune, flip game, or smth else.
