so we'll get to take it in turns um, so yeah, when you place it down, you make a move, you place a piece of redstone and then it's someone else's turn to put one down now, when you get to a situation like this, where the next piece of redstone put down creates a box whoever puts that piece of redstone down gets to take another turn and also claim that square as their own so if i were to place that there i could then claim that as my own and make another move somewhere else.
