Dice Roller

What is a dice roller?

A dice roller is a small program that stands in for a handful of physical dice. Instead of reaching for a d20 for a tabletop session or a d6 for a board game, you set how many dice you need and what type, and the tool returns a result instantly. This one supports the standard set used in tabletop gaming and probability puzzles alike — d4, d6, d8, d10, d12, d20 and d100 — so whether you just want to roll a dice for a quick decision or run a d20 roller for a combat check, the same page covers it.

Because it works with virtual dice rather than physical ones, you can roll far more at once than you could ever hold in two hands — up to 100 dice in a single roll — and add a flat modifier to the total without doing the arithmetic yourself. It behaves the same as any online dice you may have used before: pick a quantity, pick a die type, roll, read the result. There is nothing to install and nothing to configure beyond the fields on the page.

How to use it

1. Set how many dice you want. Type a number from 1 to 100 into the How many dice field — one d6 for a quick check, or a stack of them for a bigger batch roll.
2. Choose your die type. Click d4, d6, d8, d10, d12, d20 or d100 to pick which die every one of them will be for this roll.
3. Add a modifier if you need one, then roll. Enter a number from -100 to +100 in the Modifier field if your roll needs a bonus or penalty — it is added once to the total, not to each die — then press Roll dice to see every face and the total.

Are physical dice actually fair?

Ordinary dice from a board game box are not perfectly fair, and the reason is manufacturing, not superstition. Retail dice are usually made with rounded corners and pips drilled into each face, then filled with paint. Drilling six pips for the six face removes more plastic than drilling the single pip on the opposite face, so that side of the cube ends up very slightly lighter while the one side stays the heaviest. A die tends to settle with its heavy side down, which means the six comes up marginally more often than chance alone would predict. Casino dice fix this on purpose, with sharp, un-rounded edges and pips filled with a material matched to the density of the plastic, specifically to remove that bias. A virtual die never has this problem, because it has no mass, no corners and no pips to drill — every face of every die here is exactly as likely as every other.

That said, this is a simple roller, not a full virtual tabletop. There is no dice-notation box, so you cannot type something like 4d6+2 — you set the quantity, die type and modifier as three separate fields instead. There are no exploding dice, no advantage or disadvantage mechanic that rerolls and keeps the better result, and no roll history, so once you roll again the previous numbers are gone. If your game needs those house rules, you will still need to apply them yourself.

Why is it free?

FreeToGenerate.com runs every tool directly in your browser instead of on a server, so there is no per-roll cost to cover, no account to maintain, and nothing to log — which is also why reloading the page clears your results instead of storing them anywhere. Free, with no sign-up and no watermark, is simply the natural cost of a tool that does all its work on your own machine.
