Progressive side bets: Casino games like Caribbean Stud Poker commonly offer one of these. You normally lay a wager (a dollar is the usual amount) to try to win a bonus jackpot that could reach $25,000. Although big jackpots like these are very tempting, they are also incredibly difficult to win. You would need to hit a Royal Flush in order to succeed on this wager. Also, picture this- you play 20 hands and put the side wager every time. That is $20 you could have used towards the actual game bet instead of a sucker bet. Just think about what you could have been able to win at a bet with more favorable odds employing that 20 dollars.
Individual number wagers in Roulette: This is particularly true for American Roulette. Why? American Roulette has two zeroes on the wheel, as opposed to European Roulette, which has just one. This shifts the complete house advantage from 2.63% with one zero wheel to a whopping five% in American. The one number bet has only a 1 in 38 chance of succeeding, which are very big odds indeed. Bet on even-odd or black-red wagers instead which have a much smaller casino edge.
Keno: Any variation of Keno, and anyway you wager on it, the house advantage can be a huge 25%. Yes, that is not a typo. Due to the huge amount of numbers you must choose, it is not recommended to wager on Keno very much. A number of times for fun, maybe. But don’t spend all your money on it or you will immediately find yourself broke.
