I only really play this game solo, so counting the number of moves made per game is worth doing so you can try and improve on that game type later on. Therefore I've created a strip (similar to the Depth Strip) to keep track of the number of movements. The 6 sections need to be cut out and stuck together lengthways, with 1 at the top and 30 at the bottom. Then you can place it on the other side of the map, opposite the Depth Strip, and fold out how ever many sections you need. There are also basic counters to allow
for Depth 4 levels (+0/+20/+40) and Depth 6 levels (+0/+30).
