Dungeon Crawl Stone Soup (DCSS) in your pocket.

Play now: pocketzot.app

PocketZot is an unofficial, mobile-first app for playing DCSS on an iPhone or Android phone. It's a WebTiles client. It connects to standard DCSS servers over the same WebSocket protocol as the official client, but replaces the rendering and UI entirely: an ASCII-first map, a custom touch HUD, and on-screen controls designed for portrait mode.

It's also a WebTiles server. A full build of DCSS runs on the device itself, so you can play local games with no network at all. And there's no App Store or Play Store: it runs in the browser and installs to your home screen as a Progressive Web App.

• Play online (WebTiles) or offline (local).
• ASCII-first design that fits the full standard console map onto a phone in portrait mode, with a font still large enough to read.
• Graphical tiles support.
• Chat support.
• Customizable controls.
• Log in with multiple WebTiles server accounts and switch between them.
• Inline tap regions in many menus and descriptions for quick touch interaction.
• Context-aware control sets for common situations.
• Spectator mode with an expanded map view.
• Floating, collapsible monster list; tap for details.
• Map double-tap toggles zoom; two-finger long-press toggles tiles.
• Over 2.8 trillion logos.
• Installs to your home screen as a PWA.

See ABOUT.md for more, including the controls model and security details (credential handling, session cookies).
