The channel was set up in 2017 by two friends from England: Simon Anthony, a former investment banker, and Mark Goodliffe, a financial director.
[5][6] Anthony is a former member of the UK's world sudoku and world puzzle championship teams, while Goodliffe is a 13-time winner of the Times Crossword Championships and UK sudoku champion.
[5][6] Each video is generally composed of one of the two hosts presenting a puzzle with given rules and then solving it in real time, with their live commentary.
[8][9][10] The music played at the beginning and end of many videos is Mozart's Piano Sonata No.
In October 2020, a Kickstarter crowdfunding campaign was announced in order to produce a physical book with some of the channel's most popular puzzles.
