How to play Tower Siege

  1. 1

    Pick a machine, then tap an empty plot twice to build it there.

  2. 2

    Your machines earn your gold: each kill pays its bounty to whoever owns the machine that made it.

  3. 3

    Tap one of your machines to upgrade or sell it. Only the owner can.

  4. 4

    Enemies walk the path towards the keep, and fliers take their own line. Each one that gets through costs a life.

  5. 5

    Survive every wave to win. A match is 10, 20 or 30 waves.

Ways to play

Single Player
One commander defends the keep.
Shared Keep
Two commanders defend one base with one pool of lives.
Head-to-Head
Two commanders share the danger but compete for tower kills.
Team Siege
Four commanders in two teams. Team tower kills decide the winner after the final wave.

The machines

Arrow Nest, Bombard and Frost Spire
The three every commander starts with: cheap fast shots, a heavy shell that splashes, and a spire that slows everything it touches.
Arc Coil and Ballista
Unlocked with coins earned by playing: a short-range bolt that jumps between enemies, and a long-range bolt that goes straight through armour.
Sunfire Mortar and Glacier Crown
Elite machines, also unlocked with coins.
Void Lance and Tempest Spire
Two more, unlocked with gems earned from daily challenges.

The enemies range from quick Runners and Grunts to armoured Brutes, flying Wings, Wardens and the Siege Beast.

Tips

  • Cover the fliers' line early. Ground towers alone won't stop them.
  • Slowing machines make every other tower near them better.
  • In team modes, talk about who builds where so your gold isn't spent twice on the same corner.
