It doesn't work very well. There is no way of telling which cards are held and which aren't. Possibly because the link to the bootstrap code is a 404.
I found through experimentation that I could hold cards by clicking on them once. There is no graphical representation that the cards are held, but when I make the 2nd deal the cards I clicked on don't change.
Except when I get a good starting hand. I got two pairs, clicked on the 4 paired cards, redealt, and they all changed!
I guess what was happening was that the game was auto-holding the two pairs for me, and my clicks were un-holding them.
Sigh. What a mess.
This just cost me 10.5 BTC from my bonus.
It is possible to see that clicking the cards changes something by inspecting the card element.
When a card isn't held, it looks like this (the "HOLD" has class ng-hide):
And when it is held, it looks like this (the "HOLD" isn't hidden):
Here's the error I see in the console which may or not be connected to this bug (the bootstrap css isn't found):
I guess I'll have to cancel the bonus now that I've lost almost all of it figuring out what was going on with this broken game.
It wasnt like that before.
Happened to me too, but I thought it was just bc I was drunk.
