About this app

Sandbox & Dungeons is a living world simulator designed for D&D 5E and Pathfinder game masters. The world doesn't wait for you to sit down and play: as your players complete their quests, kings rise and fall, armies march, epidemics spread, and heroes age, session after session, even when no one is watching.

Generate a complete world in seconds—continents, factions, races, religions, economy, and threats—and let it evolve on its own. You decide how much the world intervenes and how much you control from the DM Intervention panel: declare wars, found cities, cause disasters, or resurrect fallen kingdoms with a single touch.

WORLD CREATION
• Choose the number and size of continents, the dominant race, and which races are present (17 races from D&D and Pathfinder).

• Six game themes: Free, Golden Age, Age of Wars, Dark Age, Age of Exploration, and Ancient Age.

Each world generates factions, rulers, a pantheon of 18 gods, menacing creatures, and five unique prophecies.

A WORLD THAT LIVES ON ITS OWN
Advance time in days, weeks, months, or years and watch it evolve: births, wars, alliances, famines, epidemics, migrations, and much more.

A complete chronicle of everything that has happened in your world, event by event.

A Dark King may rise as the final threat; form a resistance coalition to defeat him.

TOOLS FOR YOUR GAME TABLE
Dungeon generator with visual maps (or draw your own by hand in the editor).

Bestiary with 155 creatures from SRD 5.1, with automatically generated loot.

Shop generator, NPCs with side quests, on-demand adventure hooks, and your own quest book. • Keep track of your player group's information (PG, AC, attributes) and a log of played sessions.

• Organize multiple different campaigns within the same world.

PRIVACY AND SAVE
• Everything is saved on your device. No data leaves your phone.

• Auto-save: close the app and your world continues where you left off.

• Export or import worlds as files to create backups or transfer them to another device.

• Protect your games with fingerprint or facial recognition.

Compatible with 5th Edition (5E compatible). Sandbox & Dungeons is an independent work and is not affiliated with or endorsed by Wizards of the Coast.
A world that continues as your players complete their missions.
