巨大な扉を開ける。 それだけで、冒険が動き出す。 封印扉の向こうに待つのは、財宝か、敵か、罠か、それとも未知の何か。 1タップで扉を開き、現れた結果を見て「持ち帰る」か「さらに潜る」かを決めよう。 深く潜るほど報酬は大きくなる。 けれど、危険な結果に遭えば財宝を失うこともある。 安全に帰るか、次の扉に賭けるか。決めるのはあなただ。 【ゲームの特徴】 ・巨大な封印扉を1タップで開く、シンプルな操作 ・宝、敵、罠など、扉ごとに変わる予測不能な結果 ・財宝を100%確保する「持ち帰る」と、報酬を狙う「さらに潜る」 ・封印鍵、護符、扉機構の3つに絞った拠点強化 ・扉の自動設置、自動開扉、放置中の大扉発見が段階的に解放 ・最高の一撃は手動開扉に残る、放置と操作のバランス 強制広告はありません。 動画広告を見るかどうかは任意で、視聴しなくても遊べます。 アプリ内課金はありません。 さあ、最初の封印を砕け。

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.
