From the bridal couple's honeymoon destination to the gender of their first child to the odds of rain on the big day and what the king will say, betting websites are having a field-day ahead of Swedish Crown Princess Victoria's wedding.
In his speech to the couple on Saturday, the odds of the king saying "grandchildren" are at 1.25 to 1.0, "made for each other" at 1.75 to 1.0 and naming groom Daniel Westling's hometown of Ockelbo at 3.0 to 1.0, according to Swedish betting website Betsson.com.
On the other hand, betting that Carl XVI Gustaf will say "it just clicked" (10 to 1.0) or mention the football World Cup (50 to 1.0) might give online gamers a run for their money.
Even less probable, with 1,000 to one odds, is the chance the king will mention Princess Madeleine's ex-boyfriend Jonas Bergstroem, who is reportedly persona non grata at the palace after his engagement to Victoria's younger sister ended amidst cheating allegations.
Gamblers can also try to make a win out of where Victoria and her fiance will honeymoon, with Ladbrokes saying odds for Hawaii were better than for Brazil and Bali.
It also said there was a higher chance the newlyweds would leave the cathedral in a Volvo than in a Porsche or BMW, despite reports the couple would take a horse-drawn carriage through central Stockholm.
Another betting website, Unibet, meanwhile said there were equal odds for rain and shine on the big day, while Betsson set the odds slightly higher for rain.
In its last update Tuesday, the Swedish Meteorological Institute forecast - but did not bet - the weather would be slightly windy, and the temperature around 17 degrees Celsius (62.6 Fahrenheit) on Saturday afternoon.
It was however certain that on the royal wedding day, the sun would rise at 3:30 am (0130 GMT) and set on Stockholm at 10:07 pm (2007 GMT), the institute said.
