Purple: Right now you could take a shot and miss and then know it was a miss and then back out and try another spot until you get a hit. It would be easy to cheat. By submitting your move you avoid someone from cheating. Without a method to have your turn bounce back to you on a hit it would take forever to play a game. It is like the backgammon deal. If your opponent is stuck without a move you cant continue to play until your opponent passes. With autopass instituted into the battleboats concept, you wouldnt have to wait to continue your turn.
