Am a casino pleb myself, but I disagree with your advice about playing games only with the lowest house edge. Why? Because house edge isn't everything. Some of my biggest wins were from games with high house edge.
Indeed. Biggest wins can also be found to other games that have high house edge.
Well, it's a good idea to choose a game with low house edge for your own benefit but I think before that, ask ourselves if that's the game we prefer to play or the one that can entertain us more. If you're more concern on the house edge then probably you are a kind of gambler who's afraid to lose your money (or should I say not prepared) despite knowing the risk if you gamble it. There are plenty of games that we can choose from even we our plebs, moreover it's nice to win if you least expect it because you're just playing to entertain yourself.
