Bets range from the obvious, like who will walk Markle down the aisle now that her father has bowed out, and the color of the Queen's hat, to whether Markle's "Suits" co-star Patrick Adams will be there and the name of the couple's first child.

Markle's mother, Doria Ragland, is favored (3/10) to walk her down the aisle, beating out Prince Charles (6/1) and Prince Philip (14/1). And the odds are the queen will wear a green hat (4/6), according to Irish bookmaker Paddy Power, one of the world's biggest sports gaming companies.

Paddy Power is offering odds on the royal wedding and gamblers are going wild, rolling the dice on 13 different propositional bets.

It’s a good bet Adams will be there (1/100) and that Victoria (14/1) or Thomas (14/1) will be the name of Harry and Markle’s future royal baby.

But people are also betting on whether Markle will wear a tiara, whether Harry will wear a uniform and if he'll shave or not.

Paddy Power has suspended the bets on which designer made Markle's wedding dress because news reports and other Markle gowns indicate it's a pretty sure bet British designer Ralph & Russo made the gown.

The company makes bets based on news reports and past popularity, according to USA Today.

If you're feeling lucky, you can cast your lot on what the couple will serve for their main course, whether it will rain, which artist will play for the couple's first dance or which titles the couple will take once they're married.
