What is LOST-Challenge?
Lost, the most fantastic TV-Show out there.
This site is a tribute for all fans of the show with some skills in:
- Mathematical knowledge
The principle is based on the Level design, so you'll need some challenges solved until you can reach higher levels.
There are 6 different levels and one master challenge. The first challenges, those where you have access at the beginning are easy. Then it gets more and more difficult up the level-tree.
Not every challenge is 100% based on something that happened in that episode. Some parts are invented to make it harder, more interesting, or just to declare better what you have to do.
So, how does it work?

Lost-Chall has been operational since 2007, witnessing numerous changes over the years. I've dedicated the past 10 years to full-time software development and juggling various hobbies that don't involve a computer.
The journey has been both enjoyable and challenging, but I've reached a decision to close down the site. However, I'm open to giving it away for free to anyone interested in hosting the site. It's important to note that I was quite young when I created the site, and it doesn't adhere to best practices. There's a considerable amount of redundancy, and it relies on a framework that has been deprecated for many years (Zend) while still running on PHP 5.4.
Given these factors, a proper migration will require some time and effort. If you're interested in taking over, please don't hesitate to contact me at email@example.com.
In the event that no one steps up to run the site, I plan to shut it down at the end of 2024. At that time, I will email a zip file containing the source code, allowing you to access the answers to unsolved challenges.
Wishing you all the best,

In case you wonder why you have lost a couple ranks: I fixed a bug in the function that calculates the rank.
