This one, named "Colourama" was modelled, externally at least, on a 1940/50 vintage gaming machine, though it accepted new pennies.

An the top were 5 slots, each a different colour, whilst on the front face was a pointer which was randomly spun and indexed at one of 16 positions.

These were also of one of five colours, and if the pointer stopped at a colour which had been backed previously a dividend of from 2 to 12 pence was paid, depending on the colour.

With the aid of 3 coloured sketches Phil explained how the random spin, coin handling and pay-out were achieved.
