We start with two parallel stacks in front of a square.
The first player of the stack without disc starts and cuts diagonal. The player with the disc passes straight down the line.
Right after throwing the thrower cuts across as well and receives the disc.
The disc gets returned to the baseline straight back. (the disc never goes diagonal but only along the square outlines).
Now the next player cuts across.
And then we continue with step #2. The thrower cuts right away diagonally.
And the disc gets returned back straight… and we cycle through.
