There's nothing dishonest about casino games in regulated casinos. Detailed information on game mechanics and payout odds are generally available from one or more of the following sources: the casino, the local government gaming regulatory agency, and/or the manufacturer/publisher of the games. It takes a minimal amount of effort to figure out which games are the least likely to bleed you dry, and if you spend enough time in or around casinos, and you'll quickly notice that educated/skilled gamblers avoid slots and certain table games like the plague, and gravitate towards games that (generally, if following normal mechanics) have miniscule 'house edges' like single-deck blackjack, baccarat, certain variants of video poker, Pai Gow, etc.
