Roll Dice

What is a virtual dice roller?

A virtual dice roller does the one job a physical die does, without the die. You press a button, it tumbles, and you get a number. This one rolls one to six dice at a time with a proper tumbling animation and a sound, because a result that simply appears feels like a number generator rather than a roll.

It exists because dice go missing. They roll under the sofa during a board game, they get left in the other box, and tabletop groups end up one short of what the rules ask for. Opening a page and pressing a button solves that in about two seconds, and it works the same on a phone passed around a table as it does on a laptop.

How to roll

1. Choose how many dice you need.
2. Press Roll. The dice tumble and settle on a result.
3. The total is shown alongside the individual faces, so you can read either.
4. Roll again as many times as you like. Nothing is stored and nothing carries over.

Is a digital roll actually random?

Each roll uses the browser's random number generator, which produces a flat distribution across all six faces. In practice it is more even than a real die, because a physical die is only as fair as its manufacturing. Cheap dice have rounded corners, uneven pips drilled out of one face, and internal air bubbles, all of which bias the result slightly. Casino dice are made to much tighter tolerances precisely because of this, with razor edges and pips filled flush.

The one thing a digital roller cannot replicate is the physical ritual, and for a lot of players that ritual is the point. This is a stand-in for a missing die, not a replacement for a nice set.

What people use it for

• Board games with a lost die. The most common reason by a wide margin.
• Tabletop RPGs where you need several dice at once and only own a couple.
• Classrooms for probability lessons, where rolling a hundred times and tallying the spread is a lot faster on screen.
• Settling arguments. Highest roll wins is older than most rules.
• Picking randomly from a short list, by numbering the options one to six.

Everything else about it

It is free, it needs no account, and it works on a phone, a tablet or a desktop. There is nothing to install and nothing is sent anywhere, so it also works if you have already loaded the page and then lose signal. If you want a decision made rather than a number rolled, Decide For Me spins a wheel instead, and Coin Flip handles the two-option version.
