The Relay Challenge allows you to partner with a friend to complete a series of short tasks together, relay style. And then upon completion you both earn rewards. You may have up to 5 Relay Challenges active at any time. Head over to your Friend Center and look for the "Relay" tab.

Next, find one of your friends with whom you’d enjoy playing.  Tap the name, then hit the “Invite” button:

And now, we just wait until our friend is done. They have 24 hours to play or respond. If they don't respond, no worries – the Relay just doesn’t happen and you can simply dismiss the invite after it expires. Neither of you lose anything.

Once your friend is finished, it's your turn to complete a task.

Click 'Play' and off you go.

Once you and your friend have finished all of your tasks - you can collect your reward!

Rewards vary depending on the Relay. The more difficult a relay, the greater the rewards. Both participants will receive the same Chest, contents of which may vary.
