Welcome to r/whereintheworld`s third CTF challenge! For this edition, our theme is volcanoes! 🌋

This is our third CTF, we have implemented some of the suggestions from last time, but the website is still a work in progress, so bugs may occur.

How to Play:

Entry: Your Reddit username is your ID. There is no separate sign up or account creation required. Please use your exact Reddit username so that awarding points is simple and accurate.

Progression: There are 5 challenges this time. You must solve one to unlock the next.

Scoring: The first two challenges are worth 2 points each. Challenges 3, 4, and 5 are worth 3, 4, and 5 points respectively. The intended difficulty is roughly proportional to the points awarded, although this is admittedly subjective.

Hints: Each challenge includes optional hints. You can reveal these if you get stuck, but keep in mind that using them will reduce the points you earn for that round. Note that in this edition of the CTF, each hint costs 1 point. The hints that you didn’t use will be shown after you got the correct answer!

The Finish Line: Once you complete all challenges, you will be redirected back to this thread. Feel free to add a comment about how it worked for you, but please do not post any answers in the comments. We want to keep the game fair for everyone.

Deadline : 1 July 2026, 23:59 CEST

Results: After the round closes, I will post the final leaderboard and point totals later!

The CTF is hosted on locus-works.com. This is because the standard Reddit interface cannot support the specific format required for the game to run smoothly.

We want to be very clear that using Google Lens or AI in any form is considered cheating!

We're still in the early days of CTF, please do give us some more feedback. If you found any bugs, please report them in this post.

Good luck and have fun!
