An info section would be helpful as im not very familiar with some of the games. For example, what counts as a win in the poker game?
For poker, without any upgrades, "hi-pair" wins your wagered money back, while "hi-card" and "lo-pair" count as a loss. I mainly go by the rules outlined here: https://en.wikipedia.org/wiki/Video_poker. In a later version I will outline some of these rules in an info section.
