In Germany, the first national lockdown in response to the COVID-19 pandemic was from March to May 2020. This study explored changes in gambling behaviour after the lockdown among people who gambled offline on higher-risk forms of gambling. Survey participants were 612 adults who gambled offline on casino games, sports betting, and slot machines prior to the lockdown. Few people switched to online gambling after the lockdown. Most participants either continued to gamble offline or stopped gambling. About 37.1% of participants who bet on sports and 64.1% of participants who gambled on casino games stopped offline gambling. Female gender, younger age, and less frequent gambling were predictors of stopping offline gambling instead of continuing gambling after the lockdown. However, younger age and having more erroneous gambling beliefs were predictors of switching to online gambling.
