When I was a child there was a toy which was quite popular, probably some of you have seen it before.
...
I remember that toy and had a lot of fun playing it although I used to cheat a bit by shaking the toy to force the rings to move in the right direction

I'd love to see a casino version of it but developing one is going to be very challenging. The design and animation can be easily imitated but not how it works as winning on the real game depends on how skilled the player is and the laws of physics while the casino game needs to be based on pure luck.
It could be also implemented as a skill based game if the casino somehow manages to turn the game into a contest against other playes, like Poker is.
That way it could be a skill based game and do not translate to losses to the casino but rather to the player who plays the worst.

...I hope with technological advances this game can be lifted in online version
Actually, while searching that image I came across with an app for Iphone which seems to be an electronic version of the games, for phone obviously. That means there is already a preceding on making this game available for computers.
Eventually casinos could came with their own version if they believe it profitable.
