Posh Bingo is cashing in on the social networking craze and is using its Facebook page to promote a new offer to its followers, it has emerged.

After the group used a Gordon Brown lookalike to parade around Westminster donning ‘not too posh for bingo’ badge, the group is now inviting gamers to write bingo-related captions for the photos it took of the campaign, reports Bingo Street.

The top five wittiest comments will be chosen by Posh Bingo on the 12th of August and fans will have a 24-hour window to vote for their favourites.

Victorious writers will be announced on the 14th, with the overall winner bagging 10,000 bingo points, while four runners-up will receive 2,500 points each.

This week, Posh Bingo encouraged people to sign up for its loyalty programme and start collecting points they can turn into cash.
