Carry your soul into the depths.
Loop Dark Dungeon is an idle dungeon RPG where your adventurer explores the labyrinth automatically.
Cursed by the Demon King, a hero and the fairy Pipi are trapped in a dungeon that changes shape with every descent. Defeat the Demon King waiting on Floor 100, break the cursed relic sleeping on Floor 500, and keep descending into the endless Abyss beyond.
- EXPLORATION AND COMBAT ARE FULLY AUTOMATIC
Your adventurer walks the labyrinth, fights monsters, and picks up potions, fire bombs, and treasure chests. You just decide how they grow. Progress made while the app is closed is waiting for you when you return.
- UPGRADE, BE REBORN, GO DEEPER
Spend gold to raise Attack, HP, crit, combo rate, and more. When you hit a wall, be reborn to earn Soul Shards and grow permanently stronger through the Soul Tree.
- 4 JOBS, 8 EVOLUTIONS
Choose Swordsman, Rogue, Mage, or Paladin. At JOB Lv.10, each JOB can evolve into one of two advanced JOBs, and you can switch between them at any time.
- RELICS AND SET BONUSES
Summon weapon, armor, and skill relics from the abyss. Duplicates resonate and grow stronger, and the right combinations trigger set bonuses. The Gems used for summoning are earned in-game.
- A DIFFERENT LABYRINTH EVERY TIME
Random floor traits and events, risky forks in the path, mini-bosses every 20 floors, a daily Cursed Labyrinth, and daily missions.
- COMFORTABLE IDLE PLAY
x1/x2 exploration speed (x4 with the Adventurer Pass), an Idle Mode that dims the screen to save battery, and a 30/60fps option.
- COMPANIONS, BLACKSMITH, DAILY BOSS
Bring companions you meet in the labyrinth. Forge your weapon and fuse relics at the blacksmith. Take on a new foe every day in the Daily Boss, and compete for the deepest floor on the Game Center leaderboard.
- LOGIN BONUSES AND SEASONAL GIFTS
Daily login bonuses, plus gifts for seasonal events and every update.
- SEASONAL EVENTS AND GUARDIANS EVERY 10 FLOORS
Trade for limited companions and relics in Halloween, Christmas and New Year events. A Guardian boss with its own lines awaits every 10 floors. Collect 30 relics and 11 companions (with evolutions) in the Collection, and see how deep you can go.
