Press space to enter your dice to roll. Format your entry as "1d6", with the "1" being how many dice of that kind to roll and the "6" being how many sides the die has. Use a "+" to roll multiple dice. You must enter at least one die and a constant. Use +0 to roll the dice with no constants. Press R to reroll your dice. Examples: 2d6+3, 1d7+0, 3d10+1d6-1
