I've been in tabletop game dev for 20 years now. Please listen closely as I teach you the most important lesson I've learned.

IF YOU MAKE CUSTOM DICE WITH A LOGO YOU GET ONE FACE WITH A LOGO AND THAT FACE IS ALWAYS YOUR DIE'S HIGHEST VALUE.

Thank you.

Also the first time you produce a custom d4 you will screw it up. The numbers will not line up correctly. You will need to redo it. It's OK. Everyone makes that mistake.
