Not all video poker games are created equal, and it pays to do a little looking around. If you have several online casinos where you like to play, take the time to check pay tables before you start wagering. Those who play in brick-and-mortar casinos should do the same – I’ve often found higher and lower pay tables on the same game in different areas of one casino.
Despite the importance of finding the best machines, most players don't. That's why casinos can offer both decent and lousy machines in the same casino and be confident that gamers will still play the lousy ones. They have to keep some good machines, otherwise they'd lose all the players who know what they're doing. But most of the machines will be bad, and most gamers will play them anyway. Heck, in Vegas even casinos and supermarkets have video poker, with absolutely terrible paytables, but people will still play them rather than going across the street to a casino where they can get seven times better odds. Go figure.
