Step 1

Enter into a vertical stack

Step 2

The first cut is initiated from the back of the stack (ie. 4)

Step 3

4 reaches the front of the stack

Step 4

after reaching the front, 4 goes to the middle of the stack. As 4 goes to the middle, 3 is already making their cut but on the other side of the field.

Step 5

everyone else in the stack walks backwards making room for the front

Step 6

As 3 finishes their cut, they go to the front of the stack. At the same time, 2 makes their cut.

Step 7

The rest of the stack moves backwards.

Step 8

Repeat the process and continue

Step 9
