Roll 1–10 standard polyhedral dice with a whole-number modifier using Web Crypto rejection sampling, visible event history, and clear ordinary-use limits.
A quick decision brief for this specific tool
One to ten dice, a supported d4/d6/d8/d10/d12/d20/d100 type, and one whole-number modifier from −1000 to 1000
Individual faces, one modified event total, up to 20 validated browser-local events, and event-total average/minimum/maximum
Browser Web Crypto uint32 values mapped to faces with rejection sampling; settings are snapshotted and locked for each animated roll
Choose your path
Roll a bounded set of standard dice from browser cryptography while keeping each animated event, total, and local-history record internally consistent.
Roll several standard polyhedral dice with one game modifier.
Choose count, sides, and modifier, roll once, then inspect individual faces and the total.
Settings cannot change mid-roll and the result/history preserve the exact event configuration.
Demonstrate bounded random samples without claiming short-run balance.
Repeat supported rolls and compare event totals with the possible range and event-level history statistics.
Can distinguish observed event totals from individual-die distributions and theoretical expectation.
Know the randomness method and its scope.
Review the Web Crypto/rejection disclosure before using a low-stakes result.
Keeps gambling, regulated draws, keys, and reproducible research in appropriate audited systems.

For an s-sided die, uint32 values at or above floor(2^32 / s) × s are discarded. An accepted value maps to value mod s + 1.
face = acceptedUint32 mod sides + 1Count, sides, and modifier are snapshotted and locked during the animation so the displayed faces, total, and history record always describe the same event.
The panel accepts 1–10 dice, listed standard sides, and an integer modifier from −1000 to 1000. If secure randomness is unavailable, it reports an error instead of using a weaker source.

Choose 1–10 d4, d6, d8, d10, d12, d20, or d100 dice and an optional −1000 to 1000 whole-number modifier. Each roll uses browser Web Crypto with rejection sampling and keeps up to 20 validated roll events in this browser.
