The Demon Lord's castle turned out to be the worst company to work for.
Idle Hero Quest is an idle RPG where your heroes fight on their own — during your commute, your meetings, even while you sleep. No overtime pay required.
FEATURES
- Upgrade heroes, then just idle: gold piles up automatically
- Offline progress: earn up to 24 hours of gold while the app is closed
- Climb the Demon Castle floor by floor; every 10th floor hides an elite boss
- Fight the corporate ladder: Slime Intern, Goblin Clerk… all the way up to the Demon CEO
- Milestone levels (25/50/75/100) double a hero's DPS — pure inflation joy
- Change jobs (prestige) for Career Points and ever-faster runs
- Recruit staff from the gacha — they clock in and fight beside your heroes, each with a Power / Economy / Idle role
- Industry Map: climb the career ladder from tiny sweatshop to global conglomerate; a better company means a longer idle cap
- Daily task list plus a login bonus that grows with your streak (up to ×7)
- Achievements: permanent goals (floors cleared, job changes, hero level, recruits, bestiary, office) with Recruiting Budget rewards
- Bulk upgrade (×10 / MAX) and one-tap "equip best gear" so managing a big roster stays fast
- Now available in 한국어 (Korean) — switch anytime in Settings
PLAYER-FRIENDLY
- Ads are always optional: watch one to double a reward or skip time — every feature works without them
- No forced ads, no stamina, no account, free to play
Clock out on time. Let the heroes handle the castle.
