In the year of maybe 1988 or smth like that my uncle took me to have so fun at slot-machines house. And there was now old russian slot-machine called: naval battle

It was my first time I got to know what I am playing and then there were lots of questions to ask my uncle about submarines and how they hunt and many more
You can find this game here and have some fun playing too:
