It was reported late last year by The Times that the BBC were to pilot Thai physical gameshow 'Block Out' for a potential UK version of the show.
The physical gameshow - which draws parallels to Total Wipeout and Hole In The Wall - sees two teams of contestants contestants answer question while contorting their bodies into positions, whilst balancing on a ledge.
The aim of the game is to have their bodies in the correct position so that they're not pushed into the put by a giant shape-shifting wall which comprises of 100 blocks.
The pilot has been sat on the shelf for over six months, which has led to speculation that the format will not be progressing to a full series. The BBC declined to comment when approached by TV Zone.
CPL Productions produced the non-TX pilot. The original show was created by Japanese TV giant Nippon TV and first broadcast on Channel 7.
The pilot was first reported in The Times in December 2021.
