Series 1

The first series of The Crystal Maze Online Adventure was produced from April 24 through May 17, 2020. Hosted by Robert, the series consisted of ten teams.

Bookings for the series took place through the UK Escape Room Enthusiasts Facebook group before moving to its dedicated Facebook page from Series 2 onward. On May 17, 2020, duo Hayley & Ali won the series over Lone Wolves Die First & Bungwi, respectively.

Development
Early development for a limited series began in 2018 in the Online Reality Gaming Community which mainly comprised of competitive zero-sum games. Attempts to gather interest was met with extremely limited success and the decision to move into the Escape Room Community was met with a more positive reception in early May 2020.

Due to the overwhelming amount of bookings, scheduling was based on the availability of the team. As such, some days had three or more teams which would become more structured going into the second series. The first two episodes were played on Skype which housed five chat groups (four zones & main chat) where the nominated player would be moved into a new room then relay information back and a more complicated version of the Crystal Dome. Starting from the third episode, Zoom became the preferred method of communication and all games were viewable through one screen. The Crystal Dome underwent the biggest makeover with a more simplified version.

Unlike the television show, the use of all six zones were in play so every two teams would navigate a new variation of the Maze, some of which would not be possible. The Mega Crystal introduced in the 2019 revival series was incorporated.
