If you’re looking to build up your badge collection in Foursquare (including the recently released official Symbian version) and are in London next week, you might want to pop along to The Jewel Bar on Glasshouse Street. London cultural website Londonist is hoping to get 250 people or more to check-in at the Bar, and those that do will earn the Super Swarm badge!

As well as the race to be Mayor at each location, Foursquare offers challenges for users to go through, including visit a karaoke bar six times, head to the gym, and check-in really late on a school night.

One of the badges, the Super Swarm, has never been awarded in the UK – it’s earned when 250 people check in at the same place at the same time (or very close to the same time). Website Londonist and @LDN want to change that, so are suggesting everyone meets and checks in at The Jewel Bar next Thursday in an attempt to snag it.

And if you’re new to Foursqaure, it could be the perfect way to kick of your  badge collection!

Join me in earning the Super Swarm badge?
