Territory

Draw out from the edge and come back while you're still holding. What you closed off is yours. Anything still open to the edge stays empty.

How to play

• On a computer, move along the edge with the arrows or WASD. Hold Space to draw, and let go to return to safe ground. On a phone, turn draw on, then use the direction buttons. Turn it off and you return.
• A line that only touches a bare wall does not fill. Come back to land you already have, and what you closed off is yours. Anything still open to the edge of the board stays empty. If both sides have an enemy, you get the smaller one.
• An enemy on your open line costs a life. Let go and the line disappears — you are back on safe ground. Touch your own line and that stretch rewinds.
• Your score is 10 for each cell of land you take, plus 500 for each enemy you wrap, 100 for each second left, and 1000 for each life left.

Closing three edges of the board does not fill the field. From stage 2 a fuse follows a line you have not closed. From stage 3 a laser cuts it too. Either one costs a life.
