I like the concepts for the different gambling mini-games. I was surprised when I pressed exit and found both an exiting cutscene and copious amount of debt instead of the game closing, giving the gambling an objective as opposed to only a casino simulator.
I think the quantum roulette offers the best payout, with a bonus on having the most interactivity. I wonder what more quantum based casino minigames would look like for something like blackjack or poker?
