This is about the image of the game Random that shows as a link in the Games page and also above the name of the game when you play it. Maybe this isn't a glitch, after all I've been playing here for years and only now just noticed it? But it's weird.
The two-pips and three-pips on the dice are parallel to the edges of the cubes instead of along diagonal like most dice that show up when I search images in Google.
It's the same image used for the item Random Dice:
I've never really noticed it either, but that item is pretty old so I guess it's just always been that way.
[edit]I did look up other dice and die items on the site, and it seems like this is the only one that has them being parallel instead of diagonal. Maybe it's something that could be fixed in a revamp eventually.
