A simple cover that slides over the column of a captured number! It allows for the player piece to maintain it's dominance at the top, while making it easier to visually see what numbers are still available.

Easy to print, no supports, multi-color available for the stop signs in the middle. They fit in the box designed by @KyleKindle_119957 over on printables.

I printed using 0 degree infill direction which I found was a nicer look on these.
