On the Subject of Numpath
The one thing about computer numpads is that the numbers are never quite where you think they’d be.
Take each serial number digit in order. If any of these are zero, interpret them as one. Use the color of the displayed number to obtain a 3×3 grid. Begin in the cell whose number is on the display, and navigate to each of these digits using the directional buttons.
Attempting to move off the edge of the grid will incur a strike and reset your position.
