I ask of you one final task: find my Horseshoe Necklace lost somewhere in the YPlan app. The first 36 to find it will win a pair of tickets to go see The Libertines on Saturday 30 January. If you're game, the only weapon you need is YPlan. Here's what you've gotta do: 1/ Fire up the YPlan app once you've received a Treasure Hunt push notification (not valid on the web) 2/ Tap, scroll and scour the depths of London events to find the treasure of the week (hint: it's not as easy as searching "treasure") 3/ Found it? If you're not too late, tap "I'm In" to claim your prize 4/ Perform victory dance Don't see "I'm In?" Alas, you may be too late…but worry not. A separate invitation could still come your way. Terms and conditions: The competition will run from 8-29 January. Winners will be contacted by email using the contact details they provided when registering on the YPlan app. They'll be contacted within 1 week of the competition closing. In the case that the winner doesn't respond within 2 weeks of the competition closing, it will be redrawn. For any questions please email hello.london@yplanapp.com
