I'll give you points for creativity for not putting any literal dice in the game where it feels like every other game has a die in the game somewhere.
The art's really good, but I wasn't quite sure what was happening even though I understood the rules. Lack of gameplay aside, maybe add a pause or a part of the UI explaining which of my cards are beating which of the opponents cards; as it stands, it just seems like I spin the slot machine, I have an icon or two icons leftover, and then I get points, but I don't understand the interactions at all.
