Bingo is apparently the favourite pastime for the 24-year-old "Harry Potter" star and he was seen trying his luck at it, reports dailystar.co.uk.
An onlooker said: "We couldn't believe it when we saw him come in. He tried to be quite low-key and didn't ask for any special treatment."
"He stayed for two hours and played a couple of games, but didn't win anything. We overheard him telling pals it was his favourite hobby," the onlooker added.
