I’ve got about as many board games as I would ever need (let’s see that stop me) including most of the classic ones that immediately come to mind when “board games” are mentioned, like: Life, Monopoly, Uno, Scrabble, and Battleship. Most of those are pretty common; though, even in the middle of southwest Texas you can find those and some “designer” board games like Catan and 7 Wonders, but one of the strangest things I’ve ever found out there in the middle of nowhere is a Russian re-implementation of Battleship called космический бой.
Typing that into Google Translate will get you “Space Battle” or “Space Combat”, which is pretty accurate as the game is Battleship with the titular water-based vessels replaced with spaceships. There are a few variations: the largest ship is only 4 spaces, and there are a few 1-space “fighters”. I don’t have instructions (I say squinting at the back of the box) and can’t read Russian anyway, so I don’t know if there are any rule changes to compensate for what seem to be some annoying additions. There are some rule changes/additions in other countries and regions (Russia included) that make the game in general more playable (less boring than totally random guessing), and hopefully they had the sense to implement them here.
But other than it being obviously Battleship with everything changed slightly (the case, the ships, the pegs) I can’t give you much information about it since I can’t read Russian (or any Cyrillic language). I did find a shop listing for the game after a little internet searching, and running it through the translator doesn’t produce much clarification, though it does acknowledge that the game is a variation on Battleship, making me wonder how the copyright for the game works there (or even here, I don’t really know much about its history), and it offers a vague “Ships on the need to touch each other, the minimum distance – a single cell” that could be an answer to my rules question above. But in any case, we know from the side of the box that anyone can enjoy the game… as long as they are less than 100 years old.
