Idle games, also called incremental or clicker games, are built around numbers that keep growing. You start by clicking, then buy upgrades that do the work for you, and eventually unlock new systems that change how the whole game works. They are easy to start and surprisingly hard to put down.

What Makes a Good Idle Game

The best idle games reward both short check-ins and longer sessions. They keep introducing new mechanics, so the game feels different after a few hours than it did in the first few minutes. A good prestige system, where you reset progress in exchange for permanent bonuses, is what keeps most players coming back.

Best Idle Games on PC

• Cookie Clicker: the game that defined the genre. You bake cookies, buy grandmas and factories, and slowly uncover a strange and very funny world. It is free in a browser and paid on Steam, where it adds achievements and a soundtrack.
• Melvor Idle: an idle game inspired by RuneScape, with skills to train, bosses to fight and a huge amount of content. It is published by Jagex, the makers of RuneScape.
• Antimatter Dimensions: starts simple and keeps unfolding into new layers of mechanics for dozens of hours. It is free in a browser and on Steam.
• Idle Champions of the Forgotten Realms: a free-to-play idle game built around Dungeons & Dragons characters, also available on consoles.
• Leaf Blower Revolution: a strange and satisfying idle game about blowing leaves, which grows far more complicated than it sounds.

Best Idle Games on Mobile

• Egg, Inc.: build a chicken farm and eventually send eggs into space. It is one of the most polished idle games on iOS and Android.
• AdVenture Capitalist: a lighthearted business simulator and one of the easiest idle games to pick up.
• Legends of IdleOn: an idle MMO-style game with characters, classes and lots of systems, on mobile and Steam.

Best Free Idle Games in a Browser

• Universal Paperclips: a short, brilliant game about an AI making paperclips, which becomes something much bigger. You can finish it in a few hours.
• Cookie Clicker and Antimatter Dimensions both run free in a browser, so you can try them before deciding whether to buy on Steam.

Idle Games and In-App Purchases

Many mobile idle games are free to download but sell speed-ups and premium currency. They are usually playable without paying, but costs can add up. If you want to set a limit, using a store gift card instead of a linked bank card makes spending easier to control.

Picking Your First Idle Game

Start with Cookie Clicker if you want the classic experience, Melvor Idle if you like RPG progression, and Universal Paperclips if you want something short and clever. All three are good examples of why the genre has lasted so long.
