In 1965 I was first introduced to a flipper-less style of pinball machine used for gambling. There were 25 holes which were protected by pegs. Th object was to launch a ball and attempt to land it into specific holes, which were grouped into winning combinations. Players could insert lots of coins into the machine to gain greater payouts for winning and options to move the screen. When the screen was moved, different winning combinations were revealed. Winning was achieved by either 3, 4, or 5 balls landing in the desired line, colored sections, or group. Games were awarded onto a counter and could be sold to the proprietor. Can anyone tell me what these machines were named and where one might be available?
