About this game

Zombie Idle Tycoon is a free browser-based idle/clicker game where you build, upgrade, and manage 14 distinct zombie facilities — from a humble Zombie Hut to the world-ending Apocalypse Core. Every building generates gold per second on its own, and you can tap any active building for an instant +1.5-second bonus. Gold compounds into upgrades, which compound into a bigger income rate, which unlocks the next tier of buildings. Step away and your zombie workforce keeps earning — up to 4 hours of offline production at 50% efficiency. Hitting lifetime-gold milestones pays out Arcade Coins you can spend across the rest of the Zombie Arcade.

How to play

1. Start with a free Zombie Hut — it generates gold by itself.
2. Tap your built buildings for a quick instant gold bonus.
3. Spend gold to upgrade buildings (each level boosts income by 10%).
4. Earn enough lifetime gold to unlock the next building, then build it.
5. Close the tab and come back later — offline gold keeps stacking up.

Every building you build generates gold per second automatically. You don't have to click — but tapping gives you an instant bonus equal to ~1.5 seconds of that building's income.

Does it keep earning while I'm gone?

Yes — when you return, you'll see a Welcome Back screen with the gold your zombies earned offline (capped at 4 hours, at half the live rate).
