Tower Defence is a free strategy game you play in your browser on a phone, tablet or computer. Attackers march down the road towards your city, and the towers you build beside it are all that stands in their way. Fifty-five levels across eleven countries bring new enemies, new towers and new ground, and research between levels makes your defence stronger.
How to play
Each level has a road, a city at its end and build slots marked with a + beside the road. Tap a slot and choose a tower: towers aim and shoot by themselves.
Build first, then press Start. Enemies come in waves, and you can build, upgrade and sell in peace between them.
Gold pays for towers and upgrades. You start each level with some, and every enemy stopped pays more.
Every enemy that reaches the city costs lives. Survive every wave and the level is won; lose all your lives and it is lost.
A win earns up to three stars. Every level pays credits, which you keep and spend on research.
