Now you must decide if you want to eat a pancake or add a pancake to the stack.
To eat a pancake, remove one of the pancakes from the stack (delete one of the lines in the middle of the stack). To add a pancake, copy and paste another pancake on the stack (copy and paste one of the lines from the middle of the stack).
The game starts with 10 pancakes, and ends when either all the pancakes have been eaten, or the stack reaches 30 pancakes.
No double stacking or double eating; you must wait for someone else to either eat or stack a pancake before eating or stacking another.
