This page is an archive of helpful tools and resources one might use in the course of solving puzzles typically found in ARGs, including encipher/deciphering, audio encoding, and steganography.

ARG Training


A series of challenges meant to teach to basic elements, techniques, and dynamics of ARGs, made in-house by the Game Detectives.


ae27ff is a series of puzzles that use the typical techniques of most ARGs. They get more difficult the higher you go. Made by Discord user crashdemons.


An annual Game Detectives tradition consisting of a series of puzzles unlocking each day over advent, with varying difficulty. Created by the GameDetectives admins.

Enigma Group

A puzzle site that has many categories of learning. They begin as really easy, but then ascend to a more difficult encounter.


A series of puzzles designed to introduce people to ARG solving. They range from easy to very hard. Levels can be gained through active participation on the official forum.

Last transmision

A short, interactive, slightly creepy story made by Discord user mai(#9088). Will put your basic puzzle solving skills to the test.

Watching You

Originally forming part of an ARG, the site now houses two series of puzzles - the originals, and a cancelled Advent version. Made by Discord users in Team Look In The Bushes.
