Challenge 0.1 rules

Challenge 0.1 is free to enter and opens for everyone at the same moment. Everyone who finishes goes on the board, and two people who finish by 31 December 2026 win a prize.

Who runs it

The challenge is run by Nezir Kaan Bilgehan, trading as Lavirent, in the United Kingdom. Send any questions to [email protected].

When it opens

The challenge opens at 18:00 UK time on Tuesday 1 December 2026. Nothing of it can be seen before then, by anyone. You can create your account earlier, so you’re ready.

How to take part

1. Create an account on the play page: a username and an email address. Where the buttons are shown, you can sign in with GitHub or Google instead.
2. Once the challenge is open, work through the three stages: two photographs, then a trail. Each answer unlocks the next stage.
3. When you finish, your username goes on the board with your finishing place.

Taking part is free and there’s nothing to buy. One account per person.

Who can take part

Anyone aged 18 or over, anywhere in the world, unless the law where you live doesn’t allow it.

The board and points

The board lists everyone who has finished, in the order they finished. Your points depend on your finishing place: 100 for first, 90 for second, 80 for third, 70 for places 4 to 10, 60 for places 11 to 25, 50 for places 26 to 100, and 40 after that. Points from future challenges are added to the same total.

Once it has opened, the challenge has no end date. You can finish it and take your place on the board at any time.

The prizes

Two identical prizes, each a physical item made by Lavirent. What it is stays hidden until the final screen. There’s no cash alternative.

• First prize: the earliest finisher who makes a valid claim.
• Draw prize: one picked at random from every other valid claim.

To be in the running you must finish by 23:59 UK time on 31 December 2026. The final screen then shows your claim code. To claim, follow @lavirent_ on Instagram and send us a direct message with your username and your claim code, by 23:59 UK time on 7 January 2027. You need an Instagram account to claim; there’s no other way to claim. A claim is valid when the code matches the account that finished. One claim per person.

If you finish after 31 December 2026 you still go on the board, but there’s no prize.

The draw

The draw is made within seven days of 7 January 2027, using a random number generator. Prizes are posted once they’ve been made, and we’ll tell the winners when to expect them.

Winners

We contact winners on Instagram, and at the email address on their account if we can’t reach them there. A winner who doesn’t reply within 14 days loses the prize, and we draw again. We post prizes worldwide at our cost; any customs or import charges are the winner’s to pay. Winners are named by their username.

Fair play

• Use open sources only. Nothing in the challenge needs you to contact anyone, go anywhere in person or get into anything that isn’t public. Every stop on the trail is something we put there ourselves.
• Don’t publish the answers or the flag. We can remove accounts that finish with shared answers.
• One account per person. Don’t create accounts to take places on the board or to enter the draw more than once. We remove the extra ones.
• Don’t attack this site, our accounts or anyone else’s systems. If you do, we remove you from the board. If you find a security problem here, tell us at [email protected] instead.
• We can hide usernames that are offensive or that pretend to be someone else. Nobody from Lavirent will ever ask for your account key.

Your data

Your username and finishing place are public. Your email address is used for messages about your account or a prize, and for news only if you ask for it. The privacy notice has the details.

Instagram

This promotion is in no way sponsored, endorsed or administered by, or associated with, Instagram. By taking part you release Instagram from any responsibility connected with it.

Changes

If something outside our control makes the challenge unworkable, we may change or end it, and we’ll say so on this page. These rules are governed by the law of England and Wales.
