@Errol is being very modest. This is the best thing that has happened to text adventures in the last 40 years. I have played and completed the first four games and I’m loving every minute of it. They are very hard, but very fair. If you like text adventures and you like puzzles, you MUST give these a try.
Here’s a little more explanation for the uninitiated.
Visit the Cryptex Hunt 2021 web page. Read all the rules and make sure you know what to do. This page includes a link to the Crytex Jam web page. Click the Submissions tab to view all the games. There are 12 games altogether. They were written by various authors, so they have different styles, but the theming is consistent throughout. Errol did most of the graphics and the graphics are superb! Most of the games have an in-game map. You can play the games in any order, but I’d recommend starting with #01, as this has an in-game tutorial at the beginning, then play the rest in sequence. You need to complete #10 to get the password for #11 and you need to complete #11 to get the password for #12.
All the games were written in Adventuron and are playable in a web browser. Although you can play them on most mobile phones, it is recommended that you play them on a desktop computer or laptop because the mobile phone’s virtual keyboard takes up half the screen real estate.
There are two aspects to every game. You must play the adventure to solve the adventure, but you must also find a hidden code embedded within the game. This is the code that you need to enter on the Cryptex Hunt web site, but you must register if you want to do that. The web site will then let you know if the code is correct. If it’s not, you can play a bit more and try again.
The code is not presented to you up front. You must decode the clues and this may require some external research or Googling to find the answer. In at least two of the games I’ve played, the game will appear to end, even though you haven’t found the clues for the code. In this case, just restart the game and you will find that there are some subtle changes that will allow you to find what you need.
I hope this helps. Further hints for the games are available on the Discord server and the Cryptex Hunt web site.
According to a message on the Discord server, there have been well over 2000 plays on the first game alone, so that’s a hell of a lot of new people being introduced to text adventures, all thanks to Errol and his team. They deserve some sort of IF community award of some sort!
