Dice Roller
A Coin Flip and Dice Roller gives you instant, unbiased random results for games, decisions, and classroom probability lessons. Flipping a coin settles small disagreements fairly, while dice power board games, role-playing adventures, maths exercises, and quick team picks. This page keeps a running count of heads and tails so you can watch a fair coin settle near fifty-fifty over many flips, which is a simple, convincing way to show how randomness behaves over time instead of over just two or three tries.
The dice section is flexible enough for both family games and tabletop role-playing. You can roll between one and six dice at once and choose the number of sides, from a simple four-sided die up to the twenty-sided die famous in adventure games, or even a hundred-sided percentage roll. Every roll lists the individual dice, not just the total, so doubles and critical results are easy to spot. A short history keeps your recent rolls visible, which helps in games where several players roll in turn and results must stay fair and public.
How to use
- Press Flip Coin for a single heads or tails result and watch the running totals grow.
- Set the number of dice, from one to six, for the dice roller section.
- Choose the sides per die to match your game, such as six for most board games or twenty for role-playing.
- Press Roll Dice and read the individual results and their sum.
- Check the history box to review the last ten rolls during a game.
Frequently asked questions
Are the results really random?
The page uses the browser's built-in random generator, which is well tested and suitable for games, decisions, and teaching. Over many flips or rolls the results average out evenly. It is not certified for gambling or official draws, where regulated equipment and independent auditing are legally required, but for everyday fair picks it is entirely dependable.
Why does heads sometimes come up five times in a row?
Streaks are a normal part of randomness, not a sign the coin is biased. A fair coin has no memory, so each flip is independent. Over hundreds of flips the share of heads drifts close to half, which you can test quickly with the counter on this page and see the percentages settle.
What does d20 or d100 mean in games?
Players shorten die names to d plus the side count, so a d6 is an ordinary six-sided die, a d20 has twenty sides, and a d100 roll gives a number from one to one hundred, used for percentage chances. This roller supports all three, so one page covers most tabletop and classroom needs.
Can I roll more than six dice?
The page is limited to six at a time to keep results readable on a phone screen. If your game needs more, roll twice and add the groups together, noting each group in the history. Most traditional games rarely need more than a handful of dice in a single throw.
