So have a game that needs weird dice? That new RPG calling for d7's? You think you really need a d18 even when no game you'd ever seen has one? You can make your won.
I'm fibbing here a little of course, I not going to tell you how to make a d7 or d24 but I know how you can make a "randomizer" for any die type imaginable.
Make a custom game spinner. You can make the whole thing yourself from scratch, find components online, adapt one you "borrow" from a family game or even have one special made from an online service.
There is no excuse at not being able to have any "die" type possible. You can get as funky as you want.
