Progressive side bets: Games like Caribbean Stud Poker commonly contain one of these. You generally put a wager ($1 is the usual value) to attempt to win a bonus jackpot that could reach $25,000. Though huge jackpots like these are particularly tempting, they are also incredibly hard to win. You might have to hit a Royal Flush in order to succeed on this bet. Also, think about this- you play 20 hands and make the side bet each time. That is $20 you could have used towards the actual game wager instead of a sucker wager. Imagine what you might have been able to win at a wager with better odds employing that twenty dollars.
Individual number wagers in Roulette: This is completely true for American Roulette. Why? American Roulette has 2 zeroes on the wheel, unlike European Roulette, which has only one. This takes the complete house advantage from twopercent with a single zero wheel to a whopping five% in American. The one number wager has only a 1 in thirty eight chance of winning, which are very long odds indeed. Try even-odd or black-red wagers alternately which have a much lower house advantage.
Keno: Any version of Keno, and anyway you gamble on it, the house edge can be a whopping 25%. Yes, that wasn’t a error. Because of the huge amount of numbers you have to choose, it is not recommended to wager on Keno very much. A couple of times for entertainment, perhaps. But don’t waste all your money on it or you will quickly discover yourself beaten.
