Series 2

The second series of The Crystal Maze Online Adventure was produced from May 18 through May 24, 2020. Hosted by Robert, the series consisted of twelve teams. A second host, Joshua, joined in the seventh episode.

Bookings for the series took place through The Crystal Maze Online Adventure Facebook group. On May 24, 2020, Baldilocks & The Four Fat Dwarves won the series over Once Upon A Time & Subcultures respectively.

Development
Series 2 began the day after the conclusion of Series 1. With increased interest from people within the Escape Room Community, Robert opted to increase team size to twelve.

A new Maze Master, Joshua, who originally attached to the 2018 version was brought on after observing the sixth episode. Joshua would premiere in the seventh episode and would alternate hosting with Robert. The Mega Crystal was retired after the first series as teams were more focused on the classic version of game, though all six zones were still in rotation.

Teams
Twelve teams competed this series. One notable contestant, Cameron Stout, who won the fourth series of Big Brother UK competed in the fourth episode "Perfect Combination".
