How to play

Start a round and you will need to place and upgrade your towers so each incoming wave of enemies is stopped before it reaches the end of the path. You only need the mouse here — or one finger if you are on a phone or tablet. The difficulty builds gradually — pace yourself and you will get further each time.

Tips & tricks

If you want to get good at this quickly, start here. Cover the corners and choke points first, and pour your money into upgrading a few strong towers instead of scattering weak ones everywhere. Everything else comes down to practice, so treat the early losses as cheap lessons.
