1. Be sure to check out which games they offer and compare each game's house edge.

I agree , more or less, with every tip of yours, I just want to say that according to my observations the significance of the quoted line above is highly overestimated by some gamblers. Take, for example, a game that has just 1% house edge. Should we play only such games instead of those with 2% house edge and higher? I don't think so. It's only if you had an army of gamblers, a million of them, under your direction, and your collective task was to win as much as possible(or, rather, to lose as less as possible), then looking for games with the lowest house edge would be a great idea. For a single player, it doesn't affect his performance that much.
In general, at a distance, the difference in the house edge is of great importance, but if we are talking about an individual gambler who plays from time to time, then in fact he will not feel it. In addition, if, say, a player likes sports betting or slots, then it makes no sense for him to play dice (although the house edge is 3-4 times lower there), since he simply does not like dice, but loves other gambling games. And by the way, if you focus on this rule, then no one should play lotteries (although many people love them) since the house edge there is more than 50%.
