GameDetectives is an online community primarily dedicated to solving and documenting gaming-related ARGs and similar puzzles.
The community was created under the name Steam Sale Detectives and existed as a subreddit dedicated to uncovering the mysteries surrounding the Steam Winter Sale 2015. The subreddit proved very popular so a Discord chat server was created for real-time investigation discussion.
The community grew to over 14,000 subscribers in a very short time and, due to popular request following the conclusion of the sale, the community was kept together. The scope was expanded in order to encompass ARGs and mysteries in general. A new subreddit was created to accommodate this.
The name GameDetectives was chosen after a community-wide poll.
Since that time, a smaller but dedicated community has solidified. The community primarily inhabits both the subreddit and Discord server which, as well as tackling the latest ARGs, also hosts various chat topics (including gaming, programming, science and more).
