Battleships - rooms of house

A simple battleships game: each pair puts a cross in 5 different squares on their grid; hiding this from their partner. They then take it in turns to make a sentence - eg: J’ai un salon. If their partner has a cross in that square - they get a ‘hit’ if not; it’s a miss (they should mark a miss too so they don’t say the same sentence twice). The winner is the first one to get all 5 hits. Obviously adaptable to your own vocab.
