Click the green flag, then follow the in-game instructions. When you have to enter what type of numbers you want on your die, no answer(or an invalid answer) will be assumed to be 'normal'. ALL INPUTS MUST BE LOWERCASE. This is really useful for RPGs because you can go ahead and roll 1d3 or 1d5 without having to divide a bigger die into 2.
Mostly by me-thanks to TheNickofTime for text engine
