So, I noticed that in the new version of Yam, the dice represented during the loading screens are wrong.
Indeed, a real die is recognizable because the sum of its opposite sides is always equal to 7. Thus, 1 is opposed to 6, 2 to 5 and 3 to 4. It's a small detail but it's a rule in the dice factory to play.
I thought you might be interested in this info to make your dice more realistic. ;-)
