How It All Works

The one-sentence version

RNGESUS is a tabletop platform built around tap-to-roll dice: 3D-printed key fobs with an NFC tag inside, each with its own ID. You tap one with your phone, the app produces a roll for that die, and the number lands wherever you were pointing it — a character sheet, a VTT scene, your roll history.

The dice are physical. The rolls are digital. Your phone is the bridge. Nobody watches a die tumble across a table and reads the top face — that's a different product, and a much harder one.

You do not need dice to start

Worth saying early, because it's the thing people assume. Characters, the virtual tabletop, the tavern, guilds, the whole social side — all of it works with no tag at all, and none of it is a trial.

So the shape of it. The app, the tabletop and the social side are free and complete on their own. Tap-to-roll dice are optional, and what they add is more fun rather than more features. Nothing that works without them will ever be moved behind buying a physical product. Ever.

The first ten minutes

1. Log in. A new account lands on Start here, the first of the plain pages under VTT in the header: your games in a list, and the quickest way to a table. Everything on it lives in The Rolling Bones, which is one press away at Tavern and is two things at once: a tavern to hang around in with other players, and the lobby every game on the platform is started and joined from. It's drawn as a room you walk about rather than a page you scroll — the bar, the fireside, the quest board by the door, tables all over. Whichever of the two you reach first shows you the house rules — the landlord by the door in the tavern, a card on the plain page — and they end in a signature, so sign the book with whatever name you want the room to call you — or walk in as a stranger, which is allowed and even a little mysterious. The Tavern in this library is the full tour.

2. Pull up a chair. Tables are where games happen: sit at one and press it, and you're in a session on the virtual tabletop — starting one, or joining the game already on it. (Start a game on Start here does the same thing without the walk: it seats you at a free table.) Anyone else who sits down is at it with you. The fireside chairs and the stools at the bar are the other sort of seat, with nothing being played at either, and that's deliberate: they're for waiting on your friends, reading, talking and generally being part of the room. Getting up puts you back in the room, not out of the door.

3. Say something. On a wide screen the conversation runs down a rail beside the room; on a phone it's at the hearth. Same talk either way. At the bar you can raise a toast, which puts your words on the counter for everyone who's in. And tapping somebody's face — or right-clicking it — opens what you can do about them: take a proper look, stand them a drink, add them as a friend. Inside a session that same menu carries a whisper, for a word meant for one person.

4. Read the quest board. It hangs by the door, where you see it walking in, and it's the quickest way to find people to play with. Three piles: games after players, parties short a member, and players after a table. Pin your own sheet up from the shelf underneath — a line about what you want to play, when you're free, and what you'll never run again. "5e, weeknights, will play anything with a bard in it" does more work than a profile does. Take it down whenever you like.

If you have dice, or want some

Registering a tag is a phone job — reading and writing NFC is something only the native app can do, which is why the Add New Dice button on the web honestly just points you at the store. On the phone it's three steps: tap Scan RFID Dice, hold the phone against the fob until it reads, name the die. Your Dice covers what's actually written on a tag, and what happens if somebody else has claimed one already.

What the dice are actually for

Since none of it is locked behind them, here's the honest case for picking one up.

• A tap beats a button. Reaching for one particular die and putting your phone to it is the part of the ritual a screen throws away. Every fob has its own identity and its own sequence of numbers behind it: a tag is a thing, not a label on a shared generator.
• The rolls come back to you. Every tap is recorded against that die and against you. /dice keeps your whole history; one die's page breaks its numbers down face by face — naturals at both ends, averages, how it's really been treating you. Enough to settle an argument or start one, and you can mint a public link to a die's stats for people with no account.
• A die has a past. Each one remembers who has held it and how it changed hands. Gifts and trades only complete when the tag is physically tapped, so a die's provenance is backed by somebody actually having had the object in their hand — which is the one thing a purely digital item can never say.
• And a reputation. The shrine at the tavern keeps a charge sheet per die, declines to have an opinion under thirty rolls, and is upfront that a blessing does nothing whatsoever to the numbers.

Being honest about the state of things

• The iOS app is not on TestFlight yet, which is the main thing standing between "I read about tap-to-roll" and "I tapped a die." There's an Android client too, maintained separately.
• The virtual tabletop works and will genuinely run a session: maps on square or hex grids, fog of war with line of sight, dynamic light and ambient sound you can place, initiative, marks drawn straight onto the map, and a good deal more. Hex grids are the newest part of it, and the measuring tools — the ruler, the area shapes — still think in squares.
• The tavern is young. A great deal of it went up in a single day, and the room was rebuilt this month into the floor you now walk around. That's a fine way to build a place and a poor way to be sure every corner of it is furnished. If something looks unfinished, it might be.

Where else to look

This is the play side of things. There's a When it goes wrong shelf in this same library for the other sort of question — the app, your account, orders and shipping, and what to do when something is actually broken. If you have a problem rather than a question, start there.

Everything is on these shelves; there is no second help site to check.
