Four in ten gamblers have never actually set foot in a casino, according to research.
Nearly a quarter (23%), of those who flutter online, worry about getting it wrong in person – and 22% fret about looking out of place.
Others worry about having to travel there, or not having anyone to go with (both 20%).
Of those who have been to a casino, 15% have only done this once or twice.
A spokesman for Online Betting Guide, which commissioned the research of 1,000 adults as part of its gambling report, said: “Habits are changing all the time.
“Online gaming sites are becoming more and more popular, and in-person equivalents are evolving to meet the new needs. If they don’t, they run the risk of being left behind, as ever-more of the world moves to an online-first experience.”
The results also found 43% of gamblers feel an in-person casino has too many barriers to entry, and 32% feel more confidence behind the screen – with just 16% having more courage in the flesh.
But London (49%), Las Vegas (31%), and Paris (12%) are among the locations where gamblers would most like to gamble in person.
It also emerged 83% feel the internet has fundamentally changed the way people play.
A quarter currently gamble less than they did five years ago, with 42% typically playing between one to five times a week.
And six in ten wouldn’t be surprised if the future of gambling involved virtual casinos, such as an online simulation of a real-life casino, where they can play at home.
Playing the lottery draw (53%), betting on sport (52%), and scratch cards (41%), are the most common gambling activities.
But 40% of punters, polled via OnePoll, prefer games which require an element of skill, such as predicting sports scores or playing poker – while 16% like to leave it to pure chance, such as roulette.
OLBG’s spokesman added: “We gamble in all sorts of different ways every day – not taking out a coat when the weather ’s uncertain could even be seen as a form of gambling.
“This research really shows how much the world is changing to meet the growing demand for online content.
“But lots of people who feel put off from visiting casinos in real life would probably find they don’t really have anything to worry about.”
