Progressive side wagers: Casino games like Caribbean Stud Poker commonly offer one of these. You typically lay a bet (a dollar is the usual amt.) to try to win a side jackpot that can be upwards of $25,000. Though huge jackpots like these are particularly tempting, they are also particularly difficult to win. You would need to hit a Royal Flush in order to succeed on this wager. Also, picture this- you wager 20 hands and put the side bet every time. That is $20 you could have used towards the real game wager instead of a sucker bet. Picture what you might have been able to win at a bet with greater odds using that twenty dollars.
Single number wagers in Roulette: This is especially true for American Roulette. Why? American Roulette has two 0’s on the wheel, unlike European Roulette, which has just 1. This shifts the complete casino edge from two% with a single zero wheel to a huge 5.26% in American. The single number wager has only a 1 in thirty eight chance of winning, which are very big odds indeed. Try even-odd or black-red wagers alternately which have a much smaller house edge.
Keno: Any variation of Keno, and regardless of how you play it, the casino edge can be a huge 25%. No, that was not a typo. Because of the huge set of numbers you have to choose, it is not advisable to bet on Keno very much. A number of times for enjoyment, perhaps. But do not spend all your cash on it or you will quickly find yourself broke.
