Many players wonder if they can pack their fleet tightly together to save space, but the official rules regarding ship placement are quite specific.
Yes, ships can touch edges, but according to the Official Game Rules, they are strictly prohibited from overlapping.
Battleship Official Rules [edition not specified]
These rules correspond to the UK edition of Battleship.
Official Rule Breakdown
Regarding whether ships can touch in Battleship, the standard rules dictate that ships must be placed within the boundaries of the grid and cannot overlap each other. While the rules do not explicitly forbid ships from being adjacent (touching edges), they must remain distinct entities. Each ship must be placed either horizontally or vertically, and no two ships may occupy the same square on the ocean grid.
Example Play Situation
Alice places her Destroyer on the B2 coordinate. Bob attempts to place his Submarine on the B3 coordinate. Since the ships are adjacent but not overlapping, the placement is legal.

House Rules
[HOUSE RULE] Some players implement a 'buffer zone' rule where ships must be separated by at least one empty coordinate to increase the difficulty of the game.
Common Misconceptions
- Ships can be placed diagonally
- Ships can overlap if they are small
- Ships must be separated by empty spaces
Quick Reference

|---|---|
| Place ships horizontally or vertically | Do not overlap any ships |
