Progressive side bets: Games like Caribbean Stud Poker often contain one of these. You typically lay a bet (a dollar is the normal value) to try to win a bonus jackpot that can reach $25,000. Though big jackpots like this are extremely tempting, they are also incredibly difficult to succeed. You might need to hit a Royal Flush in order to succeed on this bet. Also, imagine this- you play 20 hands and place the side bet every time. That is 20 dollars you should have used towards the real game wager instead of a sucker wager. Imagine what you could have been able to win at a wager with greater odds utilizing that twenty dollars.
Single number bets in Roulette: This is especially true for American Roulette. Why? American Roulette has two zeroes on the wheel, unlike European Roulette, which has only one. This shifts the overall casino advantage from 2% with one zero wheel to a huge 5.26% in American. The individual number bet has just a one in thirty eight chance of succeeding, which are very big odds indeed. Bet on even-odd or black-red wagers instead which have a much lower house edge.
Keno: Any variation of Keno, and anyway you gamble on it, the house advantage can be a huge 25%. Yes, that is not a error. Because of the huge amount of numbers you must choose, it’s not recommended to play Keno very much. A number of times for enjoyment, perhaps. But do not spend all your cash on it or you will immediately find yourself bankrupt.
