itch.io

In the beginning you have to select the amount you want to bet. Later on you can unlock "Quick Bet" buttons that allows you to quickly bet 1/8, 1/4, 1/2 of your total chips in one click. Regarding the issue with the HIT button, have you tried playing in full screen? Sometimes in small screen, the button clicking area is not recognized

it’s really random, so I guess you really got unlucky. If you unlock the « bust probably » upgrade, you can see what is the probability that the next card makes you bust :)

I'd say being bad at gambling is a pretty sane thing :)
