Because DMs always need more dice

Every die you need.
None on the floor.

A full set of true 3D dice — coin, d4, d6, d8, d10, d12, d20, and d100 — that tumble across the tray, land, and add themselves up — correctly, every single time. Pick your color, your finish, your dice-box lining, and roll. Right in your browser.

The moment every table knows

"Does anyone have a d100?" Again.

Someone's d20 is under the couch. The percentile die vanished three sessions ago. The lucky set is at a friend's house — and naturally the crit table needs a roll right now, while a hand digs blindly through a bag of forty d6 and one very pointy, very smug d4. The momentum leaks out of the room one lost die at a time.

"The best die is the one you never have to go find."

How it works

Four taps to a rolling table.

01
Pick your dice
Tap to add any mix — a fistful of d6, a lonely d20, a d100 for when the crit table comes calling.
02
Open the Dice Bag
Choose a color, a finish, and a tray lining. Build a set your party will get unreasonably attached to.
03
Roll
They tumble in real 3D, ricochet off the tray walls, and settle on a face — no cup, no shaking, no elbow room required.
04
Read the total
Every top face, summed live, breakdown right there. Clear, and go tempt fate again.
The signature

Make every roll feel real.

These aren't flat numbers flashing on a screen. They're real polyhedra with weight, shine, and a face that lands up — the tactile best part of the hobby, kept alive on any device (and off your floor).

True 3D dice
Real tetrahedra, cubes, and icosahedra — plus a cylindrical coin and a faceted d100. They tumble, collide, and rest on a face you can actually read — even the d4, which normally needs a committee.
21 finishes
From matte Stone and polished Metal to glowing Lava, starry Galaxy, iridescent Opal, woven Carbon, and rippled Damascus. Build a set pretty enough to take the blame for your next nat 1.
Your own dice box
Roll onto scratched Leather, classic green Felt, warm Wood, dark Slate, or plush Velvet. Even a digital d20 deserves a nicer landing than a coffee-stained table.
Totals, done for you
Every die is read from its top face and added up live, with the full breakdown — 17 + 5 + 6 — so nobody at the table ‘helpfully’ recounts it for you.
Instant & private
No account, no install, no ads. It opens in a blink, runs in your browser, and quietly remembers your favorite set — no logins, no cloud, no newsletter from a lich.
A whole handful
Throw up to 24 dice at once and they scatter, bounce, and settle together — a fireball's worth of d6, and not one lost to the carpet.
Your dice, your rules

Amethyst gemstone d20s
on purple velvet.

Open the Dice Bag and build a set that's unmistakably yours — nine colors across twenty-one finishes, dropped onto the tray lining of your choice. Do it because it rolls fair. Do it because you like purple velvet. Both are good reasons.
