Kosmic Dungeon RPG

Kosmic Dungeon is an idle RPG: build a kingdom, collect a small army of heroes, and raid dungeons in turn-based fights you can actually read. Your city keeps producing while you're away — log back in and collect what you earned.

Part of the Dungeon gaming ecosystem. Play free with no wallet required.

WORLD THAT REMEMBERS
Every player fights across the same map. A corruption spreads hex by hex, and any commander can send a squad to push it back. Your idle sessions aren't happening in a bubble — you're shaping one shared world alongside everyone else playing right now.

BUILD YOUR CITY
Raise a kingdom from a handful of huts: a market, a barracks, a forge, a gem mine, and dozens more buildings, each with its own production curve and upgrade path. Every building you level makes your heroes stronger in a real, visible way — not a cosmetic skin.

COMMAND 27 HEROES
Recruit, level, and fuse a growing roster across seven ancestries and a dozen-plus classes — Fighter, Paladin, Ranger, Rogue, Cleric, Wizard, Barbarian, Druid, Monk, and hybrid classes that blend two disciplines into one. Gear them out with forged and enchanted equipment, build skill trees, and unlock mastery bonuses as they grow.

TURN-BASED COMBAT, NO GUESSWORK
Fights play out turn by turn so you can actually read what's happening — no random real-time flailing. Send squads on dungeon crawls with a bank-or-push decision on every floor: pull out with what you've got, or push one room deeper for a bigger haul.

HONEST ODDS
Every summon rate is printed on screen before you pull. No hidden tables, no fake near-misses, no countdown pressure on purchases. If you don't like the number, don't pull — you'll always know exactly what you're buying.

EVEN MORE TO DO
Hatch and raise dragons and pets to fight alongside your squad. Join a guild, fight in the arena, forge gear sets, chase achievements, and keep your kingdom producing while you're away — log back in and collect what you earned.

OPTIONAL PURCHASES
Extra build-queue slots, a second research slot, additional squads and hero packs are sold separately through in-app purchases. You see the price in your local App Store currency before you confirm.

PART OF DUNGEON
The wider Dungeon ecosystem includes Dungeon Wallet, a token exchange and an NFT marketplace. This App Store edition uses in-app purchases and does not include those blockchain tools.

It's a solo-built game and it's rough in a few corners. If something looks wrong or a number doesn't add up, tell us — that's worth more than a five-star review that doesn't say why.
