You know, I think it's a great idea to use the appearance of the Waterful Ring-Toss game, like this one
but to make an online game that completely depends on chance, something similar to slots.
There is a great deal of nostalgia about this game in the world, so it might be a popular online game with many millions of users.
Hey, I remember that game. I played that game when I was a child but I am not sure that it will become an online game like the other old games we've played. And that needs time before the developer will create a similar game, but if they can, maybe yes, that will be a nostalgia moment for some middle age gambler.
Maybe the developer can think about the idea of the game and create a new one that can adapt to the present to attract the young generation to play. Not to mention to have this game on the casino

Im familiar on this one but i dont believe that it could really be that possible for it to be made online or could be done via online or something because the things you would be mainly needing on putting up those
rings into that vertical line does really need up some control on how you do press out that button for pushing up water and pushes up those rings.I dont know on how it could be done
via online, considering into those factors then it is really hard to believe on.
Unless if this one would be done via VR or something then i do see the probability.
The developer may use VR technology to create the game and provide a real-life experience so users can feel themselves holding and touching the ring. But I don't know, it seems that making the game online still requires more time, and the developers still need time to think about it. There are still many old games that be transformed into an online form and if VR technology is well developed, I'm sure there are many games we can do virtually. It will provide a new experience for all of us, especially gamers who have played the game.
