When it helps
When you forgot dice at game night, play online, or need several dice and a sum at once—TRPG, board games, quick contests.
Examples
One d20 for a single check. For 2d6, choose six sides and set dice at once to 2, then use the sum. A short roll animation plays first. Percentile rules use two d10s separately.
Notes
Official tournaments may require physical dice; this is a convenience tool.
