Help - Looking for a movie, not sure if this is the one...

First of all, I was born in 1976 and I'm looking for a sci-fi movie I watched many years ago.

I remember when I was a kid (probably by the age of 6 no more, so circa 1982) watching a science fiction movie on TV. Well not sure if it was a movie or a tv series tbh, but it was definetly a sci-fi themed production , it was around 1982 and I definelty watched it on TV.

The only memory I've got involved 2 robots cheating in a card game , or a board game of some sort not sure. It's been 31 years ago, and the memory is a bit foggy, so bear with me. But I remember a guy playing a game with the robots, teaching them the rules and how to play, but eventually the robots got smart and began signaling each other with mecanical coded clues as the human couldn't understand what they were "saying" and at some point the human guy gets aware of this and starts laughing calling them cheaters. Back then as a kid, I found delightfully cute that the robots started cheating without being told to do so, like they could be little "smart machine friends" :-) (bear in mind, this all comes from the imagination of a 6 yo kid).

Could this be a scene of Silent Running? If not, does it ring a bell to anyone as to what movie could this be from? I am pretty sure this wasn't just a figment of my imagination , but probably one of my earliest memories that I would like to find out.

Thanks in advance.
