The study, led by the University of Bristol and published today (17 May) in the Journal of Gambling Studies, showed regular male gamblers were particularly prone to gambling more often online during the public lockdown in the UK, compared to their previously reported gambling habits.

Although overall men and women gambled less frequently during lockdown, partly due to betting shops being closed, some forms of gambling increased. For instance, usage of online gambling, including poker, bingo, and casino games, grew six-fold among regular gamblers. Respondents who gambled occasionally were still found to be more than twice as likely than before to gamble online. Those who struggled financially before the pandemic were more likely to report gambling during lockdown.
