About the game

The power fantasy of an MMO, with the automation of an incremental game

Make progress actively by buying upgrades, optimizing skill-tree builds, min-maxing your stats, and defeating bosses! Load up IdleOn the next day, spend your AFK gains earned while you were away, and buy MORE upgrades!

Create 11 unique Classes, from Divine Knight to Bubonic Conjuror

IdleOn lets you create 11 characters, so you'll have one of each class - each one plays a unique role in your account! Just don't forget about the secret class-line, including a secret Subclass, secret Elite-class, and secret Mastercl... I've already said too much...

Unique gameplay with non-fighting mechanics

You'll do more than just fight - in your quest toward the endgame, you'll need to attain full mastery over skills like Cooking, Woodcutting, Alchemy, Construction, and MUCH more!

Join the biggest incremental community in gaming - 200,000+ members

Developer posts, giveaways, and game discussions await you in IdleOn's Discord server!

Free-to-Play note:

IdleOn is free to play, and all classes, maps, skills, bosses, and activities are available without purchase. There is no paid DLC or exclusive gameplay content locked behind a paywall.

Optional in-game purchases are available, including helpful boosts and collectible pets, but they are not required to explore the world, unlock classes, or play through IdleOn’s core systems.

IdleOn is a long-term idler game, made for those seeking out a multi-year long experience!

Looking for a short, premium idler game instead? My new game Fortune Mill is what you want :D
