This is a pretty straight-forward solitaire implementation. The game only lets you deal one card at a time and it looks like you have an unlimited number of deals. Other than that, there's not much to say about the gameplay. One annoying thing is that it automatically resizes itself according to the size of the window. While that's fine for smaller window sizes, things get rather spread out at higher resolutions.

One interesting thing to note is how the cards are generated. Rather than loading an image for each card or even just one huge image with all the cards, Kris is dynamically putting together each card using small images of the different numbers, symbols, etc. Cool.
