Dont have your dice handy? Really wonder what the result of rolling 100d20 would be?
Dont worry anymore with this simple, but effective dice calculator. Try out combinations in an instant that you otherwise would need an hour with continuous rolling accomplishing the same.
Would also recommend trying out Snakes & Ladders with rolling 1d20 + 1d12 - 1d10 + 1d8 -1d6 +1d4. Makes for a lot more unpredictable and fun game that way.
