Any number of colours can be bet on each game, right up to the full five. The machine
has no lost; we have a genuine winner every go. No switches or relays to prevent the 12d
win from coming up, and a reliable system could be worked out on this machine. It's
easy to work out now, but back in the 1960s you would really have needed to see inside
the machine to see what was actually happening, and as twelve year old kids, that was
never going to happen!
Flasher Unit
This is a GPO 25-way uniselector, which simply does one full turn each time the
machine is played, and flashes the coloured stars and payout amounts. It's the same
flashing sequence every time, and this unit has no bearing on the final winning colour or
payout. When the uniselector completes its cycle and the machine stops, the final
winning colour has already been selected.
Above, the selector unit- a GPO 25-way uniselector.
Opposite page, Robert's Twinkle Toes. These machines were supplied by Ru.ff/er &
Walker and are in exactly the same cases as the R&W al/wins (Many Happy Returns,
Fill-em-Up etc). The R&W al/wins were manufactured by Corteen Ltd, of Erith, Kent.
I wonder whether they also produced Twinkle Toes?

Selector Unit
This unit is a 25-way switch that selects the winning colour and the payout amount as
soon as a coin is inserted. This selector moves one position if one colour is bet, moves
two positions if two colours are bet, right up to five positions if all five colours are bet.
There is only one position that pays the 12d and also one position that pays the 6d win.
There are five positions paying 4d, and eighteen positions for a 2d win.
So the winning colour and payout amount are pre-wired into the selector unit
(meaning red is the only colour that could pay the 12d, and orange is the only colour that
could win you 6d). Basically it's so simple, but of course back in the 1960s not many
people could afford to play twenty-five consecutive pennies into one slot, so working
out a system was never on the agenda. We had a bit of amusement at the time, which is
what it was all about.
