This is the accompanying app for enigame (https://enigame.de). enigame is a puzzle hunt for people who enjoy the combination of logical and out-of-the-box thinking and an homage to the infamous Arcane Game. You do not need any special knowledge to participate and succeed, you just need to know how to obtain it. Here's how it works: enigame consists of two episodes that each consist of multiple logical and creative puzzles. Each time you solve a puzzle, you advance to the next one. You need to solve the first episode completely before you advance to the second one. The solution to each puzzle is a word that may contain numbers. They are case insensitive (so you can use capslock to release some stress). The first ten teams to solve the first episode will get a headstart for the second episode. The first team to finish the last puzzle of episode three (or second to last puzzle, if no one solves the last one and so on) will win enigame 2025. Check out the demo to get a feeling for enigame.

Verdict
