Land Grab divides the world into 500 metre squares. Wherever you are, you can plant flags to capture the square you are on.
If a square is already taken, plant more flags than are currently on the square to capture it.
If you capture a square next to a square you already own, it increases the flag count on that square as well. Build territory in this way and make it hard for anyone to take your Land.
Login is simple with Facebook connect. If you run out of flags you can either wait for more to arrive or buy more in the app.
Have fun grabbing your land!
