Having a night out with your friends? Tinder's feature, Tinder Social, makes it easy to connect with other groups and paint the town red together. The feature works a lot like regular Tinder, but you're hoping to match with a group of people to meet up with instead of a single person. It was originally tested in Australia, but now that it's available in the US and few other select countries we thought we'd bring it to your attention again. A few changes have also been made since the Australian test to "deliver a more real-time experience. People can see who’s going out tonight, what they’re up to, and plan their night, easily and efficiently". If you think it sounds like fun, enable Tinder Social (a prompt should appear as soon as you update and open the app), invite friends that want to go out in your group (they have to be on Tinder and enable Tinder Social as well), then swipe like normal until you match with another nearby group that's also going out. When you find a match, you'll hop into a group chat so you can make plans that work for everyone involved.
Matches will last until noon the next day. After that, your group will expire and you'll have to start from scratch. It's worth noting, however, that enabling Tinder Social makes you visible to other Facebook friends that have Tinder Social enabled. If you're trying to use Tinder somewhat discreetly, Tinder Social is best avoided.
