Hi there, yes it helps, thanks!
In the meantime I realised that rather than battelships, it's more like the game "connect 4" - well, that's how I've been playing it anyway
I think the great thing about this game is that you can invent new ways of palying it. I mean, it could really be played liked battleships, where students mark a few "ships" or lines of 3 or 4 symbols and the other team has to guess where they are by forming sentences and seeing if they get a "hit" or not.
The possibilities are endless!
Great game, thanks
