Best online dice roller for D&D? Compare six tools

The best online dice roller depends on your table’s needs: recurring formulas, odds before a risky roll, or another game’s notation. Compare Nat20 Roller, Play5e, Tavern Tools, D20 Desk, Roll20 standalone and TinyToolz by task, not an overall ranking.

Publisher disclosure: Nat20 Roller publishes this page and owns one of the tools compared. Competitors are included because they appeared in the web search results reviewed for online D&D rollers, not because they paid for placement. No numerical scores or customer ratings are assigned.

Online dice rollers compared at a glance

Checked November 8, 2026 in desktop Chrome. We read the linked first-party pages and spot-checked the public workflows noted below. This is a publisher-run comparison, not an independent benchmark. An unverified feature is not a missing feature.

Six online dice rollers: documented features and limits
RollerDocumented reason to consider itImportant limit or check
Nat20 RollerKeep/drop, reroll-once and exploding notation; up to 20 saved formulas and 50 recent results. Separate probability, stat and combat helpers.Share links reproduce notation with a fresh roll, not a verified shared result. The initiative tracker does not track hit points or conditions.
Play5eMixed-die notation, advantage and a 20-roll history. Its page points to character-sheet attacks, spells and checks.Our two history entries disappeared after reload in this browser. The public ability-score helper worked; character-sheet integration was not tested.
Tavern ToolsStandard polyhedral dice, advantage/disadvantage, roll history and explicitly named Great Weapon Fighting and Savage Attacker features.One Great Weapon Fighting reroll was observed. Savage Attacker remains publisher-described only; edition rules and history limits were not established.
D20 DeskInline exact odds including keep/drop pools, a repeat control, 30 locally stored results and an offered embed.Keep/drop odds and repeat-two worked in the spot-check. A copied link restored formula and repeat count, but not our target threshold. Embed UI was inspected, not published.
Roll20 standaloneAdvanced notation including success tallies, Fate dice and several exploding-dice variants.Manual keep/drop, Fate and success-count rolls worked without sign-in. Quick Rolls and D20 Roll Report were locked. No virtual-tabletop features were tested.
TinyToolzA critical-hit dice toggle, six-score generation, keep/drop average previews and a documented seeded replay option.One seed/formula replayed after reload; a critical toggle doubled that roll’s dice, not its modifier. Offline behavior and other seeds were not tested.

How to choose an online dice roller

Start with the expressions you actually use, not the longest feature list. A DnD dice roller for attacks and saving throws needs a clear d20 result and modifier. A dice roller for other tabletop role playing games may need success counts, exploding dice or different dice types. Test that exact notation before a session.

Decide what must survive when you close the page: saved dice rolls, roll history, or neither. Character sheets and saved formulas solve different problems. A sheet may supply bonuses; a saved formula repeats your input. Do not assume either updates when a character changes.

Finally, separate ordinary dice rolling from analysis. A random dice roller produces an outcome; an odds display describes possible outcomes. A chart cannot establish that a particular throw was fair, and a single lucky roll cannot validate a random-number implementation.

Nat20 Roller: saved dice rolls and separate helpers

Consider this DnD dice roller for recurring formulas. Nat20 documents 20 saved dice rolls and 50 recent results. A saved formula and dice roll history survived reload in our browser. That is useful session continuity, not a guarantee across devices or after clearing browser storage.

Useful dice rolling features

To roll dice in the Nat20 dice roller, enter a formula and press Enter. Tested inputs were 2d6+3, 4d6dl1, 2d20kh1, 2d6r2 and 3d6!: modifiers, drop-lowest, advantage, reroll-once and exploding dice. Inspect the dice and total before saving the formula; these checks were not exhaustive. Source inspection also supports d4, d6, d8 and d10 notation; those sizes were not all browser-tested here.

Choose its stat roller for six scores or fixed methods. The attack roller offers AC comparison and optional damage, while the initiative tracker advances turns for up to 40 combatants. These are separate helpers, not character sheets.

Limits before you save or share

Save stores the dice notation; a copied link generates a fresh dice roll, not authenticated result proof. The initiative tool lacks hit points and conditions. Our parser rejected grouped multiplication, Fate dice and success-count syntax; another dice roller may suit those games better.

Play5e: a notation roller with a score helper

Choose the Play5e dice roller for typed dice rolling and a linked ability-score helper. To check a mixed dice roll, enter 1d8+1d6+2; to keep three of four dice, try 4d6kh3. Both produced outputs in our public tests.

Public character-creation workflow

The linked ability-score roller exposed 4d6 drop lowest, 3d6 and 4d6 rerolling 1s, with an all-six action and visible modifiers. This provides a concrete way to compare score-generation methods without assuming the dice roller itself is a complete character builder.

Roll history and sheet-integration limits

Play5e documents 20 recent dice rolls. Our two roll history entries disappeared after reload in this browser session. Character-sheet attacks, spells and checks are described, not tested. Verify persistent dice history and automatic sheet bonuses separately; a link does not confirm integration.

Tavern Tools: a visible Great Weapon Fighting control

Choose the Tavern Tools dice roller for die-count and modifier controls rather than typed formulas. Select a dice count and type, then a modifier and Normal, Advantage or Disadvantage. We tested ordinary 2d6 and the Great Weapon Fighting control, not every combination.

What the Great Weapon Fighting dice roll showed

One dice roll displayed original faces 3 and 2, then a reroll from 2 to 6: final dice 3 and 6, total 9. Two entries appeared in roll history. That visible transformation supports one interface observation, not validation of all reroll rules.

Edition and feature limits

Savage Attacker is named in the publisher’s copy, but no separate control was exposed in our check. The GWF interface did not establish edition or weapon-eligibility restrictions. Confirm your table’s rules before choosing the feature; do not assume a button implements the edition you play.

D20 Desk: inline keep/drop odds and repeated rolls

Choose the D20 Desk dice roller for odds beside a roll. Enter 4d6dl1, set repeat to two and target to 15 to inspect that workflow. Our test returned two dice rolls and displayed average 12.24, range 3–18 and 23.1% chance of 15 or more.

A different calculator workflow

Nat20’s separate calculator exposed ordinary 4d6, averaging 14, with no keep/drop control visible. Those are different distributions, not an accuracy contest. Neither displayed set of odds was independently audited in this review. D20 Desk documents broader arithmetic too, but those expressions were not exercised.

Copied settings and embed limits

A copied D20 Desk link restored the dice formula and repeat count, but target 15 reset to 12. The publisher documents 30 locally stored dice results. We inspected its embed interface without publishing it. Exploding and reroll dice are not charted per documentation; accepted notation does not guarantee exact odds.

Roll20 standalone: advanced manual dice notation

Choose Roll20’s standalone dice roller for advanced notation. Enter 4d6kh3 to keep dice, 4dF for Fate dice or 10d6>4 to count successes. All three manual dice rolls worked without sign-in. Its reference also describes exploding-dice variants, not exercised here.

Why syntax matters to the choice

A success tally counts qualifying dice rather than adding their faces. If your tabletop games use tallies, check that roll output before play. Nat20’s parser rejected this success-count expression. A familiar dice roller can be the wrong tool for another game.

Keep standalone and campaign features separate

Quick Roll buttons, custom quick-roll creation and D20 Roll Report were visibly locked behind free-account sign-in. We did not sign in. Manual rolling worked, but this is not evidence about Roll20 virtual-tabletop chat, multiplayer sharing or campaign features. Those belong to a separate review.

TinyToolz: critical dice and a narrow replay check

Choose the TinyToolz dice roller for critical dice or six-score generation. Enter 1d8+3 and compare the critical checkbox: our test changed it to 2d8+3, doubling dice without doubling the modifier. Its score control generated six values; neither action validates every expression.

Random mode versus seeded replay

With ?seed=42, 1d8+3 produced the same die face after reload. That is evidence for this one seed and formula, not every possible expression. Seeded virtual dice serve repeatability; a random dice rolling workflow serves a different purpose. Neither mode alone proves a result was honestly reported.

Limits of the spot-check

The publisher describes keep/drop average previews and offline operation. Offline behavior, privacy and other seeds were not tested. We did not compare speed or accessibility. Choose this dice roller for features you can verify, not an assumption that seeded replay is secure shared-result proof.

Switching from physical dice to a virtual dice roller

A virtual dice roller adds dice faces and modifiers; physical dice need no browser or battery. Real dice preserve the table ritual. For board games with simple totals, either can work: a digital dice set is not automatically better. Check dice types and notation when your game uses keep/drop or reroll rules.

To switch dice rollers, roll dice with one familiar formula, then check the visible dice and modifier. Save the formula only after confirming its meaning. Repeat for attacks, saving throws and damage if those are your usual jobs. Saved dice rolls and history should not be assumed to transfer between tools.

Before you start rolling together, agree whether players need a shared outcome or a dice formula. Test a copied link in another tab. For quick board games, check roll presentation before configuring presets. For recurring dice rolling sessions, test what survives reload.

What this comparison does not prove

Cryptographic random numbers do not establish comparative fairness, safety, privacy or speed. No equivalent security, timing or accessibility audit was run.

Feature overlap alone does not explain rankings; relevance, crawlability and authority also matter. No search engine or AI system is guaranteed to rank or cite this comparison.

Comparison questions

Which online dice roller is best for D&D?

There is no universal winner in this review. Compare the job you actually need: recurring formulas, inline probability, character-sheet inputs or advanced system notation. Use the linked first-party pages and test that workflow before a session.

Are saved rolls the same as shared results?

No. A saved formula helps repeat a roll. Nat20’s share link restores notation and generates a fresh result; it does not authenticate the result someone previously saw.

Does browser crypto make a roller better than competitors?

Not by itself. It describes a randomness source, not a complete comparison of implementation quality, usability or privacy. This review does not make comparative fairness claims.

Can virtual dice replace a physical dice set?

They can handle supported dice rolling tasks, but they do not reproduce every part of using physical dice. Check required dice types, battery and browser availability, and what the group expects to see. A familiar dice set may still suit your table better.

What should I check before choosing a free dice roller?

Try a normal roll, an expression with a modifier and any special notation your game needs. Inspect the result, then test whether you can save a formula and reopen it. “Free” does not mean every feature is available without an account; the Roll20 standalone page visibly distinguishes manual input from locked features.

Sources and update method

Sources are the six linked roller pages, Nat20’s linked helper pages and Play5e’s ability-score helper. Nat20’s parser and saved-roll implementation were also inspected. The shortlist came from two web-search result sets reviewed on November 8, 2026; it is not an exhaustive survey or a verified Google ranking list.

The mini-reviews identify tested inputs. Individual dice rolls demonstrate outputs, not fairness or exhaustive correctness. Screenshots and notes support the observations; untested capabilities remain qualified.

No accounts were created or signed into. No mobile viewport, speed, privacy, offline or fairness benchmark was run. Features may change: recheck sources and affected interactions on updates. Unknown capabilities are not marked absent. Try the main dice roller if its workflow matches your session.
