This piece needs a lot of work, like learning a few basics of poker and how someone usually plays a poker simulation.
Aces high is a term which usually comes up in poker, since the aces are the best value cards that you can have. I managed a pair of "bullets" and the woman politely informs me "you lose". Naturally, I was a little peeved with this, as the term Jacks or better would indicate a pair of jacks, queens, kings or aces. Not a big deal, but it does get to you after a while of playing. How can the ace be low, if a royal flush, the best hand in the game, have an ace at the very top?
Holding / toggling cards was the other major bugbear - I was dealt a flush and wanted to keep all of my cards - most games assume that you want to keep the cards and if you click on one, it flips it over, indicating that you require a replacement. Albeit a little naively, I clicked deal and promptly lost the flush, to my dismay. These sorts of issues are the sort of thing that gets people clicking away from your game, as opposed to on it.
The artwork of the cards was nice - did you draw them yourself, or borrow them from elsewhere? An option to speed up the dealing would be nice as well, since the game didn't have all that much flow for my liking.
