Progressive side bets: Casino games like Caribbean Stud Poker regularly have one of these. You typically put a bet (a dollar is the usual value) to try to win a bonus jackpot that can be upwards of $25,000. Although big jackpots like these are particularly tempting, they are also very difficult to win. You might have to hit a Royal Flush in order to hit this bet. Also, picture this- you play 20 hands and place the side bet every time. That’s twenty dollars you should have used towards the real game wager instead of a sucker bet. Just think about what you might have been able to win at a bet with better odds using that twenty dollars.
Individual number wagers in Roulette: This is particularly true for American Roulette. Why? American Roulette has two 0’s on the wheel, as opposed to European Roulette, which has just 1. This shifts the complete casino advantage from 2.63% with a single zero wheel to a huge 5.26% in American. The individual number wager has only a one in 38 chance of winning, which are very long odds indeed. Bet on even-odd or black-red wagers instead which have a much smaller casino advantage.
Keno: Any variation of Keno, and anyway you gamble on it, the casino advantage can be a huge twenty-five percent. Yes, that isn’t a typo. Due to the large set of numbers you have to pick, it is not recommended to gamble on Keno to often. A few times for fun, maybe. But don’t waste all your money on it or you will quickly find yourself bankrupt.
