Build the fort.
Stop the mobs.

The blocky tower defense game for kids and grown-ups. Grab the loot mobs drop, craft towers, and take down 10 giant bosses, right in your browser.

Works on iPad, phones, Chromebooks and computers

How it works

Easy to learn. Hard to put down.

  1. 1

    Grab the loot

    Every mob drops something: wood, stone, iron, gold, even diamonds. Tap it before it's gone!

  2. 2

    Craft your towers

    Drop Archers, Cannons, Frost Towers and more beside the path. Upgrade them into something amazing.

  3. 3

    Beat the boss

    Every world ends with a giant boss. If it reaches your fort, it's game over. Make every tower count.

10 worlds

From sunny meadows to the edge of the Void.

Every world has its own mobs, its own music and its own boss waiting at the end. Win one to unlock the next.

A battle in Grassy Meadow

World 1

Grassy Meadow

A sunny meadow. Perfect for your very first fort.

10 wavesBoss: Slime King

8 towers · 16 masteries

Mix them. Upgrade them. Combo them.

Each tower levels up three times, then picks one of two Masteries. The best forts use a bit of everything.

Tower combos

Trident Tower+Lightning Rod=2× zap!

Tridents soak mobs. Lightning hits wet mobs twice as hard.

Frost Tower+Cannon=Shatter!

Freeze them solid, then a cannonball smashes the ice.

Flame Tower+Frost Tower=Meltdown!

Fire melts frozen mobs. Pick your timing!

10 bosses

They're big. They're angry. They're coming for your fort.

And so much more

There's always one more wave.

The Workshop

Spend emeralds on upgrades that last forever: stronger walls, sharper tools, even a Boss Slayer.

Powers

Level up mid-battle and pick a power like Razor Edge, Overdrive or Firebrand.

Potions & TNT

Freeze every mob, call down thunder, or throw TNT right where it hurts.

30 challenges

Only 12 towers? No masteries? Speedy mobs? Prove you're a real pro.

Trophies & styles

48 trophies to earn. Unlock new forts, banners, trails and pops.

Easy, Normal, Hard

Gentle enough for little kids. Tough enough for their big brothers and sisters.

For grown-ups

Made for kids.
Easy on parents.

  • No ads. Ever. Nothing to click away to, nothing sneaky.
  • No in-app purchases. Emeralds are earned by playing, never bought.
  • No chat, no strangers. Just your kid, their fort, and the mobs.
  • No personal info. No email, no real names. Accounts are optional.
  • Real thinking. Planning, saving up, trying again: strategy that sneaks in.
