Dice Notation Explained
Dice notation is a standardized shorthand for describing dice rolls, commonly used in tabletop games and game rules.
Basic Format: NdS
Formula: N d S
Where:
- N = Number of dice to roll
- d = Literal "d" meaning "dice"
- S = Number of sides on each die
Common Examples
1d20
- Roll 1 twenty-sided die
- Range: 1-20
- Use: D&D ability checks, attack rolls
2d6
- Roll 2 six-sided dice
- Range: 2-12 (sum of both dice)
- Use: Monopoly, many board games, classic dice games
- Average result: 7
3d6
- Roll 3 six-sided dice
- Range: 3-18 (sum of all dice)
- Use: D&D ability score generation, character stats
- Average result: 10.5
4d6
- Roll 4 six-sided dice
- Range: 4-24
- Use: Often combined with "drop lowest" for character creation
1d4
- Roll 1 four-sided die
- Range: 1-4
- Use: Dagger damage, small effects
1d100 (or d%)
- Roll for percentage (1-100)
- Usually rolled with two d10s (tens and ones)
- Use: Percentile tables, random encounter checks
Advanced Notation (With Modifiers)
Format: NdS + M or NdS - M
Examples:
2d6+3
- Roll 2d6 and add 3 to the total
- Range: 5-15 (2-12 from dice, +3 modifier)
- Use: D&D damage with bonuses, skill checks with modifiers
1d20+5
- Roll d20 and add 5
- Range: 6-25
- Use: Attack rolls with proficiency/ability bonuses
3d8-2
- Roll 3d8 and subtract 2
- Range: 1-22 (3-24 from dice, -2 modifier)
- Use: Damage with penalties
Probability and Distributions
Single die (uniform distribution):
- 1d6: Each outcome (1-6) has equal 16.67% probability
- 1d20: Each outcome (1-20) has equal 5% probability
Multiple dice (bell curve):
- 2d6: Middle values (6-8) more likely than extremes
- Rolling 7: ~16.67% chance (most common)
- Rolling 2 or 12: ~2.78% chance each (least common)
Why this matters:
- Single die: Flat probability, all outcomes equally likely
- Multiple dice: Average results more common, extremes rare
- Affects game balance and strategy
Reading Game Rules
Example from game manual:
"Deal 1d8+2 fire damage"
Translation:
- Roll one 8-sided die
- Add 2 to the result
- Possible damage: 3-10 points
Example:
"Make a DC 15 Dexterity saving throw (1d20+DEX modifier)"
Translation:
- Roll one 20-sided die
- Add your Dexterity modifier
- If total >= 15, you succeed

Is This Dice Roller Random and Fair?
Understanding how online dice rollers generate randomness helps you trust the results.
How Computer Randomness Works
Pseudorandom Number Generators (PRNGs): Computers use mathematical algorithms to generate numbers that appear random. While technically deterministic (given the same starting "seed," you'd get the same sequence), modern PRNGs produce statistically random results indistinguishable from true randomness for practical purposes.
Cryptographically Secure Randomness: Our dice roller uses your browser's cryptographically secure random number generator (crypto.getRandomValues()), which:
- Produces unpredictable results
- Cannot be manipulated or biased
- Meets strict security standards
- Suitable for gaming and fair decisions
What this means: Each roll is genuinely random and fair - not influenced by previous rolls, time of day, or any pattern. The results are as random as rolling physical dice (without the possibility of weighted or damaged dice).
Fairness and Equal Probability
Every outcome has equal probability:
1d6 (six-sided die):
- Each face (1, 2, 3, 4, 5, 6) has exactly 16.67% chance (1/6)
- Over many rolls, each number appears approximately the same amount
- Short-term variation is normal and expected
1d20 (twenty-sided die):
- Each face (1-20) has exactly 5% chance (1/20)
- No "hot" or "cold" numbers
- Each roll is independent
Why You See Repeats
Randomness includes clustering:
It's completely normal to roll the same number multiple times in a row or see patterns. This actually *proves* the randomness - true random processes create clusters and streaks.
Examples:
- Rolling three 6s in a row on d6: 0.46% chance (rare but happens)
- Rolling the same d20 result twice consecutively: 5% chance (not unusual)
- Getting no duplicates in 10 d6 rolls: 27.2% chance (less common than you'd think)
Key insight: Our brains expect randomness to look "evenly distributed," but true randomness includes streaks, clusters, and repetitions. If results never repeated or always alternated, *that* would indicate bias.
Testing Fairness
Statistical validation: You can verify fairness by rolling many times:
- Roll 1d6 exactly 600 times
- Count occurrences of each face
- Each should appear ~100 times (+/-10 is normal variance)
- No number should dominate significantly
Expected distribution:
- Perfect theoretical: 100 of each (1, 2, 3, 4, 5, 6)
- Realistic actual: 95-105 of each (normal statistical variance)
- Suspicious: One number appearing 150+ times
Comparison to Physical Dice
Online dice advantages:
- No manufacturing defects
- No wear and tear affecting balance
- No weighted dice possible
- Truly random (no physical bias from rolling technique)
- Instant results
- Perfect record keeping (if logged)
Physical dice advantages:
- Tactile satisfaction
- Social experience
- No technology required
- "True" physical randomness (quantum uncertainty)
Bottom line: For game purposes, our online dice roller is as fair as - or fairer than - physical dice, since it eliminates manufacturing defects and rolling technique bias.
Common Use Cases
The online dice roller serves various purposes from gaming to decision-making.
1. Dungeons & Dragons (D&D) and Tabletop RPGs
The d20 system:
Ability checks:
- Roll 1d20 + ability modifier + proficiency (if applicable)
- Compare to Difficulty Class (DC)
- Success if total >= DC
Attack rolls:
- Roll 1d20 + attack bonus
- Compare to target's Armor Class (AC)
- Hit if roll >= AC
Saving throws:
- Roll 1d20 + saving throw modifier
- Success if total >= DC
Damage rolls: Different weapons use different dice:
- Dagger: 1d4
- Shortsword: 1d6
- Longsword: 1d8
- Greatsword: 2d6
- Greataxe: 1d12
Character creation:
- Standard: Roll 4d6, drop the lowest, sum the remaining three
- Classic: Roll 3d6 for each ability score
- Hit points: Roll hit die (d6 to d12 depending on class) per level
Critical hits:
- Natural 20 on d20 attack roll
- Roll damage dice twice
2. Board Games
Classic board games using dice:
Monopoly:
- Roll 2d6 to move
- Doubles let you roll again
- Three doubles in a row = go to jail
Yahtzee:
- Roll 5d6
- Reroll selected dice up to 2 more times
- Score based on combinations
Backgammon:
- Roll 2d6 to determine moves
- Doubles give four moves instead of two
Settlers of Catan:
- Roll 2d6 for resource production
- 7 rolled activates robber
Risk:
- Attacker rolls up to 3d6
- Defender rolls up to 2d6
- Compare highest dice to determine combat
3. Classroom and Educational Activities
Random selection:
- Roll d20-d30 to call on students fairly
- Ensures equal opportunity for participation
- Eliminates teacher bias
Math practice:
- Roll 2d6, practice addition (sum the dice)

4. Quick Decisions and Randomization
When you can't decide:
Choose between options:
- 2 options: Roll 1d2 (or flip a coin)
- 3 options: Roll 1d6 (1-2 = option A, 3-4 = option B, 5-6 = option C)
- 4-6 options: Assign each a number, roll appropriate die
Examples:
- "What should I have for dinner?" (4 restaurants = d4)
- "Which movie should we watch?" (5 choices = assign 1-5 to d6, reroll if 6)
- "Who goes first in the game?" (3 players = highest d20 wins)
Fair distribution:
- Chore assignment
- Turn order in games
- Picking team captains
- Deciding seating arrangements

6. Random Tables and Encounters
RPG random encounters: Create encounter tables with d20, d100, or custom dice:
Example d20 encounter table:
- 1-5: No encounter
- 6-10: Minor creature (goblins)
- 11-15: Moderate threat (ogre)
- 16-19: Major encounter (dragon)
- 20: Special/legendary encounter
Loot tables:
- Roll d100 on treasure tables
- Determine random magical items
- Generate quest rewards
NPC characteristics:
- Roll 3d6 for six ability scores
- Roll d100 for personality traits
- Roll d20 for mood/disposition
Troubleshooting
Common issues and solutions when using the virtual dice roller.
"I need a d100 or percentile die"
Solution using custom dice:
- Switch to "Custom Dice" tab
- Enter 100 for number of sides
- Set number of dice to 1
- Click "Roll" for result (1-100)
Traditional percentile method: If you prefer the classic two-d10 method:
- Roll 1d10 twice (or 2d10 at once)
- Designate one die as "tens" digit
- Designate other die as "ones" digit
- Combine:
- Roll 4 and 7 = 47
- Roll 0 and 0 = 100 (by convention)
"How do I roll multiple dice?"
Using the Number of Dice control:
- Select your die type (d4, d6, d8, d10, d12, or d20)
- Use the "Number of Dice" selector
- Choose how many dice to roll (1-100)
- Click "Roll"
Examples:
- 2 dice: Select d6, set number to 2, roll for 2d6
- 3 dice: Select d6, set number to 3, roll for 3d6
- 6 dice: Select d6, set number to 6, roll for 6d6
For different dice types: Roll them separately:
- Roll 1d20 for attack
- Then roll 1d8+3 for damage
- Results are independent
"Why did I roll the same number twice in a row?"
This is completely normal and expected!
Probability:
- On d6: 16.67% chance (1 in 6) to repeat any specific number
- On d20: 5% chance (1 in 20) to repeat any specific number
Independent rolls: Each roll is completely independent. Previous results don't affect future rolls, just like flipping a coin:
- Flip heads, then heads again = normal
- Roll 6, then 6 again = normal
- Roll 20, then 20 again = lucky but normal
Streaks happen:
- Rolling the same number 3 times in a row on d6 = 0.46% (will happen)
- Rolling four 1s in a row on d20 = 0.000625% (very rare but possible)
If it never repeated, THAT would be suspicious! True randomness includes clusters, streaks, and patterns. Our brains expect "random" to mean "evenly spread out," but that's not how probability works.
"My custom dice aren't working"
Check your input:
Valid inputs:
- Minimum sides: 2 (like a coin)
- Maximum sides: 1000+ (very large dice)
- Must be whole numbers (integers only)
Invalid inputs that cause errors:
- Decimal numbers: 6.5
- Negative numbers: -6
- Zero or one: 0, 1
- Letters or symbols: d6, 6d
Correct custom dice examples:
- 2 sides (coin flip)
- 7 sides (days of week)
- 26 sides (alphabet)
- 100 sides (percentile)
- 365 sides (days in year)
"Can I add modifiers to my rolls?"
Current functionality: The dice roller shows individual die results. To apply modifiers:
Manual calculation:
- Roll your dice (e.g., 2d6)
- Note the results (e.g., 3 and 5 = 8)
- Add your modifier manually (e.g., 8 + 3 = 11)
Example for D&D:
- Roll 1d20 for attack
- Result: 14
- Add attack bonus: +5
- Final total: 14 + 5 = 19
Tip: Keep a calculator handy or do simple addition mentally for most modifiers.
"The results don't look random to me"
Understanding randomness:
What randomness is:
- Unpredictable outcomes
- Equal probability for each result over many rolls
- Includes clusters, streaks, and gaps
What randomness is NOT:
- Evenly distributed in small samples
- Alternating patterns
- "Taking turns" between numbers
- Always different from the previous result
Verification method: Roll the same die 100 times and track results:
- Each face should appear roughly equally (+/-10%)
- No number should dominate significantly
- Patterns average out over large samples
Short-term vs. long-term:
- Short-term (10 rolls): Wide variation is normal
- Long-term (1000 rolls): Converges to expected probability
Frequently Asked Questions (FAQ)

2. Can I roll multiple dice at once (like 2 dice or 6 dice)?
Yes! You can roll up to 100 dice simultaneously.
How to roll multiple dice:
- Select your die type (d4, d6, d8, d10, d12, or d20)
- Use the "Number of Dice" selector
- Choose 2, 3, 4, 5, 6, or any number up to 100
- Click "Roll"
Common multiple dice scenarios:
- 2d6: Board games like Monopoly, classic dice games
- 3d6: D&D ability score generation
- 4d6: Character creation (often drop lowest)
- 6d6: Yahtzee, fireball damage in D&D
- 10d6: High-level spell damage
Results display: You'll see each individual die result plus the total sum of all dice.
3. What do d4/d6/d8/d10/d12/d20 mean?
The "d" notation is shorthand for dice types, where "d" stands for "die" and the number indicates sides:
d4 = 4-sided die (pyramid shape, values 1-4) d6 = 6-sided die (standard cube, values 1-6) d8 = 8-sided die (octahedron, values 1-8) d10 = 10-sided die (pentagonal trapezohedron, values 0-9 or 1-10) d12 = 12-sided die (dodecahedron, values 1-12) d20 = 20-sided die (icosahedron, values 1-20)
Quick translation:
- "Roll a d20" = Roll one 20-sided die
- "Roll 2d6" = Roll two 6-sided dice
- "Roll 3d8" = Roll three 8-sided dice
These are the polyhedral dice commonly used in tabletop role-playing games.
4. What is dice notation (like 2d6+3)?
Dice notation is a standardized shorthand for describing dice rolls, especially in tabletop games.
Basic format: NdS
- N = Number of dice
- d = "Dice" (literal)
- S = Number of sides per die
Examples:
- 1d20 = Roll one 20-sided die
- 2d6 = Roll two 6-sided dice, sum them
- 3d8 = Roll three 8-sided dice, sum them
With modifiers: NdS+M
- 2d6+3 = Roll two 6-sided dice, sum them, then add 3
- 1d20+5 = Roll one 20-sided die and add 5
- 4d6-1 = Roll four 6-sided dice, sum them, then subtract 1
Reading in context:
- "Deal 2d6+3 fire damage" = Roll two 6-sided dice, add them together, add 3 to the total
- "Make a DC 15 check (1d20+modifier)" = Roll d20, add your modifier, try to get 15 or higher
5. Does this dice roller support custom-sided dice?
Yes! Our dice roller supports custom dice with any number of sides.
How to use custom dice:
- Click the "Custom Dice" tab
- Enter the number of sides (2 to 1000+)
- Set how many dice to roll
- Click "Roll"
Example custom dice:
- d2 (1-2) - Coin flip equivalent
- d3 (1-3) - Three-way choice
- d7 (1-7) - Days of the week
- d26 (1-26) - Alphabet letters
- d100 (1-100) - Percentile rolls
- d365 (1-365) - Days in a year
Use cases:
- Non-standard RPG systems
- Educational activities
- Custom board games
- Decision-making with odd number of options
- Game design and testing
6. Is this dice roller random and fair?
Yes, our dice roller uses cryptographically secure randomness to ensure fair results.
How it works:
- Uses browser's
crypto.getRandomValues()API - Cryptographically secure random number generator (CSPRNG)
- Produces unpredictable, unbiased results
- Cannot be manipulated or gamed
What this means:
- Each outcome has exactly equal probability
- Previous rolls don't affect future rolls
- Results are as random as physical dice (or better, since there's no physical bias)
- Suitable for serious gaming and fair decision-making
Verification: Over many rolls, each face appears approximately equally:
- Roll 600 times on d6: Each face (1-6) should appear ~100 times
- Normal variance: +/-10 from expected value is typical
- Suspicious: One number appearing 2x more than others
Why you can trust it: The same cryptographic random generator is used for:
- Security-sensitive applications
- Cryptocurrency
- Online gaming platforms
- Scientific simulations
7. Why do I sometimes get the same result twice (or more)?
This is completely normal and proves the randomness is working!
Independent rolls: Each roll is independent - previous results don't affect future rolls. It's exactly like flipping a coin:
- Heads, then heads again = normal (50% chance)
- Tails three times in a row = unlikely but normal (12.5% chance)
Dice probability:
- Rolling same d6 twice: 16.67% chance (happens often)
- Rolling same d20 twice: 5% chance (happens regularly)
- Rolling same d6 three times: 0.46% chance (rare but happens)
Why streaks occur: True randomness includes clusters and patterns. If results never repeated or always alternated, *that* would indicate bias or predetermined patterns.
Example analogy: If you shuffle a deck of cards perfectly, you'd occasionally see consecutive cards of the same suit. That's randomness - unpredictability includes clusters.
Long-term fairness: Roll any die 100 times and each face will appear roughly equally. Short-term variation is expected and normal.
8. Can I use this for D&D and tabletop RPGs?
Absolutely! Our dice roller is perfect for Dungeons & Dragons and all tabletop RPGs.
Supported dice:
- d4 (dagger damage, small effects)
- d6 (ability scores, various weapons)
- d8 (longsword, hit dice for some classes)
- d10 (percentile rolls, heavy weapons)
- d12 (greataxe, barbarian hit dice)
- d20 (attacks, checks, saves - the core D&D die)
Common D&D uses:
- Attack rolls: 1d20 + attack bonus vs. AC
- Damage rolls: Various (1d4 to 1d12 or higher)
- Ability checks: 1d20 + ability modifier + proficiency
- Saving throws: 1d20 + save modifier vs. DC
- Initiative: 1d20 + Dexterity modifier

9. Can I roll a d100 or percentile die?
Yes! Use the custom dice feature to roll d100.
How to roll d100:
- Switch to "Custom Dice" tab
- Enter 100 for number of sides
- Click "Roll"
- Result: 1-100
What is a percentile roll? A percentile (d100 or d%) roll gives a result from 1 to 100, often used for:
- Percentage-based outcomes
- Random tables with 100 entries
- Critical hit/fumble extended tables
- Loot and treasure tables
- Weather determination
- Random encounter severity
Traditional method (two d10s): Tabletop gamers typically use two d10 dice:
- One d10 represents the "tens" digit (00, 10, 20, ... 90)
- Other d10 represents the "ones" digit (0, 1, 2, ... 9)
- Combine them: 40 + 7 = 47
- Special case: 00 + 0 = 100 (by convention)
Using our roller: Either method works:
- Use custom d100 directly
- Roll 1d10 twice and combine manually
10. Does it save roll history or show totals?
Current functionality:
What is shown:
- Individual results for each die rolled
- Automatic total when rolling multiple dice
Examples:
- Roll 2d6 -> Results: 4, 5 -> Total: 9
- Roll 3d8 -> Results: 2, 7, 6 -> Total: 15
Not currently saved:
- Previous rolls are not stored
- No persistent history across sessions
- Roll again to generate new results
Benefits of current approach:
- Maximum privacy (no data stored)
- Clean interface (no clutter from old rolls)
- Fast performance (no database overhead)
Workaround for tracking: If you need to track results:
- Write down results as you roll
- Use notes app alongside dice roller
- Copy results to spreadsheet for analysis
- Take screenshots if needed for reference
