XYZPuzzle is another HTML-based puzzle game. It currently has 99 levels + 2 bonus + 12 void, but i will add more so stay tuned.
The goal of this game is to find the correct URL to the next levels.
The puzzles start easy but get progressively harder. They involve ciphers, researching information, manipulating files, creativity and more.
The only rules of this game are to not cheat and have fun :)
Also feel free to solve this with your friends.
