A significant challenge in this level is the presence of pins with numbers on them (e.g., '3', '2', '1'), which indicates a limited number of times they can be moved. The player must strategize carefully, as once a pin's move count reaches zero, it becomes fixed in place.
Using up a full spool of thread removes it from the top row and often causes a new colored pin to appear on the puzzle grid, dynamically changing the layout. The player's strategy involves frequently swapping the positions of different colored pins and prioritizing which threads to use based on the current pin layout.
