Proposition wagers in Craps: These Craps wagers basically means you are betting that a particular action might develop on the next toss. For example, you might make the 'hard ways' wager, which indicates that you are betting that the shooter will roll a four, six, eight, or ten by rolling a double. These bets have a house edge of anywhere from 9.1-11.1%. This is a massive house advantage, and it's very abnormal that they hit.
Tie bet in Baccarat: This is a bet that no one, the bank or the player will win, but that both hands will tie. This is a very rare occurrence in net Baccarat, therefore the casino advantage is high. At fourteen% casino edge, this is the quintisential definition of a sucker bet.
Insurance wager in Black Jack: Although Blackjack has one of the lowest casino advantages (and there is also a ton of talent required), this is a sucker wager. Depending on how many decks of cards are being played and the table rules, the casino edge of this is at least five percent, but can be as great as 14%. Only very accomplished card counters are able to make this bet work for them, and even then it is still a sucker bet.
