If you haven't created a Snapchat Lens yet, first - download Lens Studio. Then, read our Terms and Conditions and register using the form below and go straight to Lens Studio to create your Lens. Once it's ready, select the Challenge tag when publishing your Lens to Snapchat.

There is no submission fee, you can take part free of charge.

As long as your Lens has the "ch0throwback" tag on it, you are entered into the contest. The Challenge Tag becomes available to you within 48 hours of registering for the contest.

You will have a couple of days after the contest closes to still tag your Lens.

Please DO NOT tag Lenses that are not related to the competition, and do not tag Lenses that are not newly created for this competition.

Unfortunately, you will not have access to the Challenge Tag until you have registered for the contest on the Lenslist site below, and you have waited the 48 hour period for us to add the tag to your account.

Be sure you applied the Challenge Tag from My Lenses to your published Lens. If you feel there has been a mistake, please email [email protected].
