Dice tools – roller, TRPG checks, dice stats

Choose a dice tool

Pick what you need: quick rolls, TRPG checks, or odds and distributions.

Dice Roller

Roll d4–d100 with quick buttons or expressions like 2d6+3, see totals and breakdowns, keep history, and share text or PNG cards.

Open Dice Roller

TRPG dice check

Run d20 checks with advantage or disadvantage, compare against a DC, and roll dice pools to count successes with a compact summary.

Open TRPG dice check

Dice stats

Compute odds like “2d6+3 ≥ 10,” switch between Exact and Sim automatically, and view mean/SD, modes, and histograms. Share via text, PNG, or URL.

Open Dice stats

Quick start

1) Choose a tool. Use Dice Roller for free-form rolls, TRPG dice check for checks, and Dice stats for odds and distributions.
2) Roll and read. Keep the browser window open during your session and read totals, successes, or probabilities at a glance.
3) Share if needed. Copy text logs, PNG cards, or prefilled URLs to share with your group.

Fair play tips

Agree on one tool before the session starts.

Keep all players on the same mode and dice expression.

Share logs right after key rolls in long sessions.

If needed, rerun with the same seed to verify replayable results.

For tournaments, write the rule set and keep it fixed for all rounds.

Keep one clear record for each turn so disputes can be resolved quickly and fairly.

If a roll decides a major event, announce the exact formula out loud before rolling so everyone checks the same rule.

Choose the right dice workflow

Use this hub when the output must follow dice rules, not a generic random picker. Start from the play format: a quick roll, a TRPG success check, or a distribution/odds question.

Open these first

Open Dice Roller when you need immediate rolls, notation like 2d6+3, and readable history.
Open TRPG dice check when the rule set uses d20 checks, DC comparison, advantage/disadvantage, or success pools.
Open Dice stats when you need probability, expectation, or the full distribution before the session starts.

Use another tool when

Open Random picker if you are choosing names or items rather than rolling dice notation.
Open Weighted random picker if entries need custom probabilities instead of standard dice odds.
Open Random & lotteries if the next question leaves dice and becomes a broader draw or simulation workflow.

FAQ

Which dice page should I open first for a live game?

Start with Dice Roller for quick rolls and visible history. Switch to TRPG dice check when the game needs DC comparison, advantage, or pool-style success counting.

When do I need Dice stats instead of the rolling tools?

Use Dice stats before the session when you need to compare odds, distributions, or expected values. Use the rolling tools when the outcome must be generated live.

What belongs here instead of Random picker?

Stay in Dice tools when the result must follow dice notation or tabletop rules. Use Random picker only when you are selecting list items and dice mechanics are irrelevant.

How do I keep rolls fair and reviewable?

Agree on one page before the session starts, keep the same expression or rule set for all players, and share logs immediately after key rolls when the table needs a clear record.
