Edges are checked as you place
Every tile edge has one of four sockets, and two tiles fit when the facing sockets match. The editor knows which, so it can show you where a tile will go before you drop it, and flag a seam that does not join.
How it works
Hexagons that only fit one way round
The tiles are flat-top hexagons printed on one face, so they turn in six steps and never flip over. Each of the six edges is either solid rock, a full-width opening, water, or a corridor mouth. Two tiles join when the facing edges are the same kind of opening. That is the whole rule, and it is what the editor checks for you while you build.
Your collection is the limit
Tell it how many packs of each set you own. Place a tile and that copy is gone, because in real life it is. Nothing you build needs tiles you do not have.
One dungeon, several storeys
A dungeon is a stack of levels in one document, numbered however you like. They share the inventory, so a tile standing on the ground floor is not available for the basement below it.
Notes where they belong
Write on the whole dungeon, on one storey, or on a single room. Room notes are the ones you will reach for most: who is in there, and what happens when the door opens.
Scenarios to start from
Prebuilt maps ship with the editor, dressed with pieces and written up with a hook and a note in every room that matters. Load one and it becomes a map of your own.
Saved in your browser
Maps live in your browser's own storage, so there is no account to make and no server holding a copy. Export one as a file when you want it elsewhere, or when you want to hand it to a player.
Why it works this way
It plans a map you can actually put on the table
Plenty of tools will draw you a dungeon. This one starts from the box on your shelf: one copy of each tile, and no more. Counting spans every storey, so a three-level delve is checked against the same single set you would be laying out for real.
You finish with a list of tiles you already own.
Where it is up to
Early, and honest about it
You build maps by hand today. Automatic generation is planned, but it is deliberately not here yet: placing tiles yourself has to work properly first. Locking a tile already pins it as an anchor for when generation does arrive.
There is one known gap. Each physical set is eighteen double-sided hexagons plus a blank, so two of the images can be two faces of the same piece, and those two could never both be on your table at once. The editor does not yet know which images pair up. A map it calls legal might therefore need one tile flipped two ways at once, which is worth an eye when you lay it out for real.
The artwork
Realm Brew, by The Shop of Many Things
The tiles and the pieces that dress them are Realm Brew, published by The Shop of Many Things. Delvewright is a tool for using that artwork, not a way to get it. If you like what you see on a map here, the tiles are theirs and worth buying.
