Retro Tech Tuesday: Merlin electronic game

I remember finding a Merlin in a forgotten corner of my house. While it was from before my time, I was fascinated by the array of touch buttons, even if I could never figure out what to do with the darn thing. Thanks to this commercial I now know about the six(!) different electronic games you could play on Merlin. But I challenge anyone to explain to me how Blackjack worked in any playable manner. Enjoy this commercial which I think also serves to show we don't have enough musical ditties in electronics commercials anymore. (And kids, if you find one of these at a yard sale "penlite batteries" are AA.)
