There are dice rollers out there, but lots of them need you to type numbers in boxes. This is OK for computers with keyboards, but tapping is much more user friendly when using a stylus. So, I made this little HTML Javascript number. I actually started with the dice roller on the wizards site (cos I know nothing about javascript), but it is practically all re-written except for the random number function (don't sue me,
WotC!!)
It is visually unappealling as it stands but replace my terrible gifs with the dice
gifs from the wizards' dice roller it looks quite nice. It can only roll standard dice, but the only input is by tapping. You roll single die or any combination and get a total.
