Battleships Pirates

Same idea as the classic pen-and-paper Battleship, just with a pirate coat of paint over the ships and boards. You place a fleet of differently sized ships on your grid, then take turns guessing coordinates to sink the opponent's fleet before they sink yours. How you arrange your ships matters more than it looks — an obvious pattern gets found fast, while spreading them out or breaking up the usual shapes buys you time. Simple rules, but there's real strategy hiding in the setup phase.
