I came across TV listings for CHCH Ch 11 Hamilton, Ontario from the mid 70s and here's the titles I discovered:
1) "Five of a Kind" (1973-75) my guess is they had 5 spinning numbers 1-6 and they used a stopper to stop which morphed into the 1975 CBS series "Spinoff" with Jim Lange
2) "Double Exposure" (1975-76) my guess is that it's their version of the short lived 1961 CBS series
3) "Hot Hand" (1976-77) my guess is they were playing poker
