In the last few years, dating couple Victoria Hoo, 23, and Nicolas Amet, 24, have taken part in various contests and won many prizes.
These include a Sony DSLR camera, a Canon Ixus digital-video camera, more than $1,000 in cash, a trip to Hong Kong with VIP tickets to a Manchester City football game, and $60,000 worth of prizes for their dream wedding.
After they received that last prize for winning radio station Kiss92FM's Perfect Match contest, netizens recognised them as serial contest winners.
Facebook users posted links to other contests that the pair had previously won, wondering how it was possible that they could be so lucky.
In fact, the answer is quite simple - they enter many contests, says Ms Hoo, who owns two fashion boutique stores.
"I love entering all kinds of competitions. Not many Singaporeans actually bother to take part in these contests and honestly, the prizes are really good," she says.
"I've liked entering contests since I was in secondary school."
She adds that Mr Amet, a fast-cars sales consultant, was initially dismissive of her contest-entering frenzy.
"He used to say to me, why do you always enter this kind of thing?" she says. "Then he entered a mio TV contest by himself without telling me and won, so now he's into it too."
They typically enter contests that require submissions of some kind, whether written, video or even in-person participation, says Ms Hoo, adding that they also enter road-show contests whenever they spot them.
"I think they are pretty easy to win, as a lot of Singaporeans find it embarrassing and shy away from this type of contests on stage. But we can laugh at ourselves," says Ms Hoo.
