Dice Roller

What this tool does

Dice Roller throws a chosen number of dice of a selected type, from a 4-sided die up to a percentile d100, showing every individual result along with the running total. Standard six-sided dice display as pip faces, and every roll is logged to a local history you can clear at any time.

Tabletop games, probability lessons and quick decision-making all rely on dice, but a physical set does not always cover every die type a game needs, and rolling a dozen dice by hand is slow to tally up. A digital roller fills the gap without needing a drawer full of polyhedral dice.

This roller supports the standard tabletop set, d4 through d20, plus a percentile d100, and lets you roll any number of them at once rather than one at a time. Six-sided results render as classic pip faces for a familiar look, while other die types show the plain number. Every roll adds an entry to a local history so you can review or recount a sequence of throws.

How to use Dice Roller

1. Choose a Die type from d4 up to d100.
2. Set the Number of dice to roll together.
3. Press Roll to throw them and see each individual result.
4. Read the Total, which sums every die in that roll.
5. Check Roll history for a record of every past roll this session.
6. Press Clear to reset the history when starting a new game or session.

Tips for better results

• Pip faces only render for d6; every other die type shows its plain numeric result, which is standard for polyhedral dice without a universal pip convention.
• Rolling a large number of dice at once, such as 20d6 for a damage pool, is faster than rolling smaller batches repeatedly.
• The roll history keeps a readable summary string for each past roll, handy for double-checking a contested result.
• Clear the history between unrelated games so old rolls do not get confused with the current session.

Common use cases

• Rolling attack, damage or skill checks for tabletop role-playing games.
• Running probability demonstrations in a classroom, such as showing the distribution of 2d6 totals.
• Settling a quick decision or game tiebreaker with a simple die roll.
• Simulating board game mechanics that need an unusual die type, like a d12 or d100.

Common mistakes to avoid

• Assuming every die type renders pips like a d6; other die types only show the number since there is no standard pip layout above six faces.
• Rolling an extremely large batch of dice and expecting the per-die breakdown to stay easy to scan; for very large pools, the running total is usually the figure that matters most.
• Forgetting the roll history only lives in this browser session and is not saved anywhere else.
