Question 1

What is Rollstones?

Accepted Answer

Rollstones is a free, browser-based 3D dice roller for tabletop role-playing games. You pick the dice you need — coin, d4, d6, d8, d10, d12, d20, or d100 — and they tumble across a tray in true 3D, land on a face, and add themselves up. It is part of the Grimshackle family of Game Master tools and runs entirely in your browser with no account and nothing to install.

Question 2

Is it free? Is there a catch?

Accepted Answer

Yes — Rollstones is free to use. There is no account to create, no software to install, and no paywall on its dice, colors, finishes, or tray linings. It runs as a single web page in any modern browser.

Question 3

Do I need an account or a download?

Accepted Answer

No. Rollstones runs entirely in your web browser with no sign-up, no login, and no download. You open the page and start rolling immediately, on desktop, tablet, or phone.

Question 4

Does it work on mobile?

Accepted Answer

Yes. Rollstones works in any modern browser on desktop, tablet, or phone, and the layout adapts to the screen — on a wide screen the dice tray sits beside your controls, and on a phone it stacks into a single column.

Question 5

Is my data private?

Accepted Answer

Yes. Rollstones keeps your chosen dice, colors, and tray lining on your own device rather than on a server, so there is nothing to sync and no account to manage. Your set is remembered locally in your browser between visits.

Question 6

What dice can I roll?

Accepted Answer

Rollstones includes a full set of eight: a two-sided coin, a d4, d6, d8, d10, d12, d20, and a d100. You can add any combination to the tray and roll them together in a single throw.

Question 7

Are these real 3D dice?

Accepted Answer

Yes. Every die in Rollstones is a real three-dimensional polyhedron — a tetrahedron for the d4, a cube for the d6, an icosahedron for the d20, and so on — rendered with depth, lighting, and perspective. They tumble, bounce off the tray walls, collide with each other, and settle on a face, rather than flashing a flat number on the screen.

Question 8

How does it decide the result?

Accepted Answer

Rollstones reads each die from the face that lands upward after it settles, exactly like a physical die on a table. Nothing is chosen in advance — the number genuinely comes from where the die comes to rest.

Question 9

Is the d100 a real hundred-sided die?

Accepted Answer

The Rollstones d100 is a faceted, many-sided die with its rolled value shown in a window as it comes to rest. It rolls to a fair number from 1 to 100, reeling through numbers as it slows and locking in when it stops.

Question 10

How many dice can I roll at once?

Accepted Answer

You can roll up to 24 dice in a single throw in Rollstones. Small handfuls tumble with full physics; very large handfuls settle instantly so the roll always stays smooth and fast.

Question 11

Can I change the color of the dice?

Accepted Answer

Yes. Rollstones offers nine dice colors — Navy, Amethyst, Sapphire, Teal, Emerald, Amber, Ruby, Rose, and Graphite — and the color applies to every die on the tray at once.

Question 12

What finishes are there?

Accepted Answer

Rollstones has 21 procedural finishes. Color-tinted finishes include Stone, Gemstone, Metal, Glass, Marble, Obsidian, Frosted, Galaxy, Speckled, Pearl, Neon, and Opal, and fixed unique finishes include Lava, Wood, Chrome, Toxic, Aurora, Carbon, Holographic, Amber, and Damascus. Each is drawn with gradients rather than images, so the app stays tiny and fast.

Question 13

What is the Dice Box?

Accepted Answer

The Dice Box in Rollstones is the tray your dice land on, and you can change its lining. There are five surfaces — scratched Leather, classic green Felt, warm Wood, dark Slate, and plush Velvet — each rendered as a textured, tactile surface.

Question 14

Can I really roll on purple velvet?

Accepted Answer

Yes. Choose the Amethyst color and the Velvet dice-box lining and you will roll purple gemstone dice on a purple velvet tray. Rollstones is built for exactly that kind of personal touch — pick your set because it rolls fair, or simply because you like the way it looks.

Question 15

How do I roll?

Accepted Answer

In Rollstones, tap the dice you want to add them to your set, then press Roll. The dice are thrown into the tray, tumble in 3D, and settle — and a running total appears with the individual results that make it up.

Question 16

How is the total calculated?

Accepted Answer

Rollstones reads each settled die from its top face and adds them together, showing both the sum and the per-die breakdown — for example 17 + 5 + 6 — right on the tray. Coins are shown as heads or tails and do not add to the numeric total.

Question 17

Does it remember my dice?

Accepted Answer

Yes. Rollstones saves your chosen color, finish, and tray lining locally in your browser, so the set you built is waiting for you the next time you open it — no account required.

Question 18

How does Rollstones fit with the Grimshackle tools?

Accepted Answer

Rollstones is the dice roller in the Grimshackle family, alongside Battlesmith for building and running encounters, with Tavernwright and Shoppekeep on the way. Each is a free, browser-based Game Master tool that shares the same look and the same no-install, private-to-your-device approach.

Question 19

Who made it?

Accepted Answer

Rollstones was built by a Game Master, for Game Masters — out of a love for running games and the simple truth that a table always needs more dice. The guiding idea across the whole Grimshackle family is to take away the friction and leave the fun.

Question 20

Is it free? How is it funded?

Accepted Answer

Rollstones is free to use, with no account, no ads, and no paywall on its dice or customization. It is part of the self-funded Grimshackle family of tools, and it is free to use today.
