Is the "no ships adjacent to other ships" rule part of the original commercial Battleship game? When I played it with my family, we didn't follow that rule, and so there was considerable scope for ambiguity about whether nearby hits were part of the same ship or not.
Of all of the assembly required, I wonder why just this one sticker on the outside. The interior had insert cards/stickers for the ocean and other inserts in the lid to look like HUD console or something [0]. So why not make thos assembly required too?
European versions have this rule [1]. I wasn't aware that the US version allowed adjacent ship placement until I bought a commercial version for my kid last Christmas and started looking into strategies.
It's not weird. I played article version my whole life and never knew different ones existed. It could help you if you're lucky enough to hit it. But it also can help you if this is your last ship on the board, which happens quite often actually.
I don't know why it would be a rule but the one time I tried it, I got absolutely rekt and never did it again.
May have been because I put ALL my ships in one big blob, but typically people will fire at adjacent hits until they don't get any, so I think it's a terrible strategy anyway.
