The Undervaults

A complete solo dungeon crawler — playable right now.

No printer, no group, no signup. THE UNDERVAULTS is a solo roll-and-write dungeon crawler: roll two dice, draw the room onto your gridded Vault Sheet, fight what's inside with dice-and-strikethrough, log the loot, and descend. One player, one pencil (or your browser), one evening per delve. You're a field assessor for the Guild of Ruin-Appraisers, auditing the vaults of a bankrupt empire — every monster a liability, and dying costs extra.

Play it now

The first depth is playable right at the top of this page — roll, draw, fight, descend, nothing to install. Want more room, or to keep it in its own window? Play the demo full-screen on our site →

Prefer paper?

Grab the free print-and-play pack. The Quickstart (rules) → holds every rule for the three demo delves, and the sheet pack → — Vault Sheet, Assessor's Licence, Guild Ledger — is clean for black-and-white printing.

Rather not flip between the rules and your pages?

The Records Clerk → runs a delve on your phone while you fill the sheets. It draws nothing for you; it keeps the books and tells you what comes next. Free.
