Instructions for the dice roller app:
The app is configured to roll up to 4 pairs of six-sided dice.
For games that require fewer dice, the un-needed dice can be configured to show a blank/inactive status image.
A short click on any die image will roll all the dice.
A long click on any die image will toggle the visibility of that dice pair.
By default the dice-rolling sound effect is off. To toggle the sound effect on/off, first turn off the visibility of all dice, then tap the screen.
