LONDON — So now that the United States Supreme Court has cleared the way for gambling on sports, what does a world with legalized sports betting look like?

To find an answer to that question, one only has to gaze across the Atlantic Ocean, to Britain and other European countries, where gambling is as much a part of the sports culture as wearing the home team’s jersey to the game.

Gambling here is, in a word, ubiquitous, and the only limit for bettors is their imagination. Bettors place wagers before the game and during it. They wager on who will score the next goal, or how many goals will be scored in the final 10 minutes or in stoppage time.

Oddsmakers offer a dizzying array of betting permutations. If that is not enough, they even offer gamblers the chance to design their own bet. A yellow card in the second half injury time, followed by a red card and a disallowed goal? They will give you a line on that.
