I came back week after week and had the fun of a lifetime. It took me six months to figure out the dice. In those days you had to roll a d6 and on a 1-2-3 you added nothing and on a 4-5-6 you added ten to the twenty sided die that you rolled. Figuring out the die to use for weapons and monsters and even reading the 4 sider was work. I learned how to trail map from Don Arnt. That is the easiest mapping form as it just notes the paths in the four directions and the doors. The chamber sizes don’t matter. Later, I would learn how to map out dungeon rooms and that was a lot of fun as Gary called out the distances in a chamber and I could sometimes figure out where a secret door was located. It wasn’t until years later that I found out that sometimes Gary had two chambers connected to one secret door. Depending on if you pressed the right or left side of the door was the chamber you were allowed to enter.
