Series 5

The fifth series of The Crystal Maze Online Adventure was produced from June 11 through June 22, 2020. Hosted by Robert and Joshua alternating episodes, the series consisted of thirteen teams.

Bookings for the series took place through The Crystal Maze Online Adventure Facebook group. On June 22, 2020, The Mind Bogglers won the series over The Gang Does The Crystal Maze and Central Belters respectively.

Development
Whilst the fifth series had confirmed teams booked in, the intention to introduce original concepts became a main focus. In Series 1, the Mega Crystal concept was used and was re-imagined to the Double Crystal for Series 5. The aesthetics for the series changed with a more bolder colour scheme for the logo and the name dropped to the bottom. This would be retained until Series 8.

The Double Crystal would be introduced in the thirteenth overall game of each team where the Captain would be given the offer with the caveat of failing to win the game would result in a Crystal being taken away as punishment. As this was optional, the team did not have to accept the deal. Twelve of the thirteen teams took the offer, and would be a mainstay for future series.

Both Robert and Joshua have stated that Series 5 has been their favourite series to host with the strongest teams to that point.
