Which dice or number tool do you need?
The right tool depends on what the random result is for. A game table, a classroom, a lottery ticket and a new bank card each need something slightly different.

How do you know the results are fair?
The results are fair because every WheelySpin tool picks with the browser’s secure random generator, the same one browsers use for encryption, not a basic math shortcut. Each outcome is fixed before a wheel spins or a die tumbles, so the animation is only for show.
The generator is also matched to your options in a way that gives every option an equal share. Without that step, a range that doesn’t divide evenly can quietly favour the lower numbers. With it, every number, face or entry has exactly the same chance.
You don’t have to take our word for it. The randomness audit runs up to 100,000 spins on your own entries, puts each result’s real share next to its expected share, and runs a chi-square test. A p-value above 0.01 means the spread looks like true chance.
Number tools: ranges, lines, codes, letters and dates
The number tools turn one question, “pick something at random,” into the exact format you need, whether that’s one number, a ticket line, a code or a whole list of dates.
The Random Number Generator handles negative numbers and huge ranges, has no repeats switched on by default, and can sort results. For a crowd, switch to the number wheel with ranges of 1–10, 1–20, 1–50 or 1–100. A spinning wheel on a projector builds more suspense than a number that just appears.
The Lottery Number Generator makes 1, 3, 5 or 10 lines at once, never repeats a main number within a line, and draws bonus balls separately, just like a real draw. Choose Custom game for a local lottery or an office pool with its own rules.
The Random PIN Generator makes 4, 5, 6 or 8-digit codes and filters out the guessable ones: common PINs, easy runs like 4321 and birthday-style numbers. Pick six digits where you can, because six digits give 100 times more combinations than four. Your PIN is created on your device and never sent anywhere.
For words and calendars, the Random Letter Generator can leave out Q, X and Z for word games, or remove each letter once it’s picked. The Random Date Generator picks up to 1,000 dates between any two days, can stick to weekdays or weekends, counts February 29 only in leap years, and exports to CSV.
Dice tools for tabletop players
The Dice Roller covers every standard die from d4 to d100, so one tab can replace a whole dice bag.
Add a flat modifier to any roll, and use advantage or disadvantage on a d20. Advantage keeps the higher of two d20s and disadvantage keeps the lower. It applies to the d20 itself, not to damage dice, a rule new players often get wrong at the table.
Making a character? The D&D Stat Roller rolls all six ability scores at once using 4d6 drop lowest, or 3d6 straight if your group plays old-school. Each score comes with its modifier (score minus 10, divided by 2, rounded down) and a total. Then you assign them to Strength, Dexterity, Constitution, Intelligence, Wisdom and Charisma and copy them to your sheet.
Not sure whether to roll or use the standard array of 15, 14, 13, 12, 10 and 8? Rolling gives a wider spread, with some heroes much stronger and some weaker. The array keeps everyone level. Many tables let a player reroll if the total modifier comes out at 0 or less.
Two dice games you can play right in the browser
Liar’s Dice and Sic Bo are complete games, not just rollers, and both run on a phone with no app download.
Liar’s Dice Online works two ways. Pass one device around the table using the Peek button, or let everyone use “Just my dice cup” on their own phone and bid out loud. Turn on “ones are wild” for bigger, riskier bids. The odds helper shows how likely any bid is. As a rule of thumb, about one in six unseen dice will match a bid face, or one in three when ones are wild. Perudo and Dudo fans will feel at home.
The Sic Bo Dice Simulator lays out the full three-dice board: Big and Small, exact totals, doubles, triples, two-dice combinations and single numbers. You start with 1,000 play chips that have no cash value. It’s a safe way to see why Big and Small, at about a 2.8% house edge, are the gentlest bets, while a specific triple pays 180:1 for good reason. Of the 216 possible results, totals of 10 and 11 come up most, 27 ways each.
Coin flips and bingo calls for groups
A coin flip and a bingo caller are the two tools that work best with an audience, because everyone can see the result at once.
Flip a Coin keeps a running count of heads and tails and tracks streaks. Don’t be surprised if a long session finishes at 49% or 51% instead of a perfect 50/50. That’s normal random variation, and it shrinks the more you flip. Choosing between more than two options? Spin the wheel instead.
The Bingo Number Generator calls 75-ball (B-I-N-G-O, 1–75) or 90-ball (1–90) games. It lights up each number on a board, never calls a number twice, and can call automatically every few seconds. Turn on “Say each number out loud” and your device reads the calls for you. The game saves in your browser, so an accidental refresh won’t wipe the board. It calls numbers only, so bring printed cards.
Popular ways to use these tools
Most people come for one quick result, but these tools are just as useful for regular events:
- Game night: split into sides with the Random Team Generator, then play Liar’s Dice on everyone’s phone and Sic Bo with play chips.
- RPG sessions: the Dice Roller for combat and the D&D Stat Roller for new characters.
- Classrooms: the number wheel or the Random Name Picker on a projector for picking students, and the letter generator for spelling games. See all our classroom tools.
- Community events: the bingo caller with voice on, in full screen.
- Office pools: 10 lottery lines in one click, copied to the group chat.
- Everyday security: a fresh 6-digit PIN that isn’t a birthday.

Frequently asked questions
Are the dice and number results really random?
Yes. Every WheelySpin dice, number and coin tool uses the browser’s secure random generator, so each outcome has an equal chance. Each roll or flip is independent of the last one. You can test this yourself with the randomness audit.
Does a random lottery line improve my chances of winning?
No. A random lottery line has exactly the same chance as any other combination in a fair draw. What it can do is steer you away from popular picks like birthdays, which many other players choose too, so a win is less likely to be shared.
Can I pick random numbers without repeats?
Yes. The Random Number Generator has no repeats switched on by default and can draw up to 1,000 different numbers at once from any range between −1,000,000,000 and 1,000,000,000.
Which dice can the online dice roller roll?
The WheelySpin Dice Roller rolls every standard die from d4 to d100: d4, d6, d8, d10, d12, d20 and d100. It also handles modifiers and advantage or disadvantage on d20 rolls.
Is it safe to generate a PIN online?
Yes, with WheelySpin’s PIN generator. The PIN is created inside your own browser and is never stored or sent to the site. It also skips weak codes like 1234, 1111 and 0000 by default.
Does the Sic Bo simulator use real money?
No. The Sic Bo Dice Simulator uses 1,000 play chips with no cash value, and there’s no sign-up or purchase. It’s built for learning the bets and payouts, not for gambling.
What is the difference between 75-ball and 90-ball bingo?
75-ball bingo uses numbers 1–75 under the letters B, I, N, G and O on 5×5 cards, and is the common format in the US. 90-ball bingo uses numbers 1–90 on cards with three rows and is popular in the UK. The Bingo Number Generator calls both.
Do I need to sign up or install anything?
No. All 11 tools run in your browser with no account and nothing to install. JavaScript just needs to be switched on.
