Is this idle tower defense game free to play?

Yes. Idle Tower Defense is completely free and runs in your browser — no download, no signup, no app install. Your progress saves automatically.

Do my towers keep fighting while I'm away?

Yes. It is an idle TD, so your towers keep dealing damage and earning gold while you idle, and you collect offline progress when you return.

How do I beat the bosses?

Bosses have huge health pools, so the goal is raw DPS — buy and upgrade more towers, stack damage multipliers, then let your sustained tower fire grind the boss down before it overruns you.

Idle Tower Defense — Free Browser TD Incremental

Tower defenseIdle TDIncrementalNo download

Idle Tower Defense is a free idle TD game you play right in the browser. Build a wall of towers, stack up your total DPS, and let them grind through an endless stream of enemies and bosses — no path-drawing or micro-management, just pure incremental damage. Every wave you clear drops gold to reinvest into stronger towers and damage multipliers, so the numbers keep snowballing wave after wave.

If you like tower defense incremental games that respect your time — no install, no signup, no pay-to-win — this is built for exactly that. Tap to chip in early damage, then sit back and let your towers idle-farm waves and bosses around the clock.

About the game, how to play & FAQ

How to play Idle Tower Defense

Build towers: buy towers from the shop — each one adds permanent DPS that auto-attacks the current enemy.
Tap to help: click the enemy to deal bonus hits, handy in the early game before your DPS ramps up.
Clear endless waves: defeat each enemy to earn gold and advance the stage; the deeper you push, the tougher (and more rewarding) the enemies.
Beat bosses: boss stages have huge health bars — out-DPS them with more towers and upgrades to break through.
Idle / offline: your towers keep fighting while you're away — collect offline progress when you return.

Tips

Total DPS is everything, so reinvest gold the moment you can afford the next tower or damage upgrade rather than hoarding. When a boss wall stalls you, grind a few easier waves to bank gold, buy a DPS spike, then push through.
