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



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

Every world ends with a giant boss. If it reaches your fort, it's game over. Make every tower count.
10 worlds
Every world has its own mobs, its own music and its own boss waiting at the end. Win one to unlock the next.

World 1
A sunny meadow. Perfect for your very first fort.
8 towers · 16 masteries
Each tower levels up three times, then picks one of two Masteries. The best forts use a bit of everything.

For grown-ups
