[Helix perks slightly with curiosity, the specific kind of game slipping his mind for a moment. Once he sees those big letters across the top an idea immediately pops into his head. The way the other boy was dropping hints at him was just to hard to ignore so he went with it.]
The rules are that every hit to a ship means the opponent has to remove a piece of clothing.
[And knowing them it didn't matter if there were enough hits to match articles of clothing on their body. Once the other was naked either boy could get distracted from the game entirely.]
If you run out of clothes then... dunno, we'll wing it. But the winner may get to sink their battleship [That got a suggestive purr and a look.]
