About this project

I’m Kamil Fiks, the developer behind Idle Center. I build the games hosted here: a game studio tycoon about growing a catalog that earns for you, an evolution clicker about growing an energy engine, and a medieval economy game about keeping a production chain supplied. All three are playable now, with progress saved in your browser.

Choose your next game

Idle Center is a growing collection of free idle games, also known as incremental or clicker games, that you can play instantly in your browser. No download, no account and no pay-to-win: just tap, upgrade, and watch your world grow. Every game runs on desktop and mobile, and your progress saves automatically to your device.

Idle games to play at work or on a break

Idle and incremental games suit short breaks: a session can be two minutes of tapping or a quick check on your catalog or production chain. All the games run in a normal browser tab with no download or sign-up, and progress saves to your browser so you can pick up where you left off. Primordial Tap also credits up to four hours of income when you return after closing it; IdleCenter does the same, up to eight hours, once you research Offline Progress; Realm Forge only progresses while its tab stays open.

Three different ways to build an idle engine

  • IdleCenter: an idle game studio tycoon. Pair topics with genres, ship games into a catalog that keeps paying you, hire a team, research upgrades and found a new studio with Legacy.
  • Primordial Tap: an evolution idle clicker. Guide life from primordial ooze to a time-travelling civilisation across 18 stages, with science trivia gates, achievements and an extinction prestige system.
  • Realm Forge: a medieval economy idle game. Forge swords, master a living market, build guild production chains, enact royal decrees and conquer the known world across four phases.

Which game fits your session?

IdleCenter: planning and a growing catalog

Start in a garage with a single idea. Choose topic and genre combos, polish and release games, and let the catalog earn while you research and hire. Pick this if you like long-run planning and discovering which combos pay best.

Your first release lands within about a minute, and the first Legacy reset takes roughly 60 to 90 minutes. Closed time only earns once you research Offline Progress, up to eight hours.

Primordial Tap: tapping and milestones

Start with one organism and turn manual energy into passive upgrades. Pick this if you enjoy a clear next evolution target, science trivia and a prestige loop.

Its generators work while the game is open, and when you return after closing it, it credits up to four hours away at half your passive income.

Realm Forge: prices and production

Start with iron and an anvil. Adjust sword prices, hire workers and later balance food, mining, smelting and workshops. Pick this if you enjoy finding the bottleneck in an economy.

While the tab remains open, it compensates for delayed updates, capped at one hour per gap. Closing the game saves your state but does not generate more resources.

Frequently asked questions

What are idle and incremental games?
Idle games (also called incremental or clicker games) reward steady progress: you start by clicking to earn a resource, buy upgrades that generate that resource automatically, and watch the numbers grow into ever-larger milestones. The fun is in optimising the loop and unlocking new mechanics — and many idle games keep progressing even while you are away.
Are the games on Idle Center free?
Yes. Every game on Idle Center is completely free, runs in your browser with no download and no account, and has no pay-to-win purchases.
Do I need to create an account or install anything?
No. The games load instantly in any modern browser on desktop or mobile. Your progress saves automatically to your device — no sign-up, no app store, no install.
Where is my progress saved?
Progress is stored in your browser’s local storage on the device you play on. It does not sync between devices, and clearing your browser data will erase it.
Which game should I start with?
IdleCenter is our flagship: a studio tycoon where you ship games, build a catalog that earns for you and plan your research, with a first release inside a minute. Primordial Tap is an evolution clicker, quick to pick up and great if you like tapping and steady milestones. Realm Forge is a deeper medieval economy game with a market, production chains and conquest. All three are free, so try whichever theme appeals to you.
