As seen on BBC TV's 'House Party' the equipment consists of a 5ft diameter disc surrounded by an inflatable safety mattress divided into eight different coloured segments, on top of each segment is a pocket into which the notice of a prize or forfeit can be placed.

Single contestants sit on the circular disc which is then spun around at an increasing speed until they come off - the segment upon which they land dictates the prize or forfeit.

A prize can also be awarded for the person who stays on the disc for the longest period of time, this can also apply to teams of 2 or 3 people.
