About Tower Siege

You stack defensive blocks into a tower, then watch enemies try to tear it down. Tower Siege deals you a hand of four pieces each round – stone walls, archer platforms, cannons, mortars and tesla coils – and gives you seconds to slot them into your growing fortress before the next wave spawns. Goblins swarm the base, boar-riders charge from a distance, fire-hounds ignite your wooden sections, and siege engines lob boulders that collapse entire floors. Any block that loses the structure beneath it tumbles, and falling debris crushes units below.

You collect wood, stone and gold from kills, spend them in a tech tree between waves, and push as many rounds as your tower can survive. Each enemy type forces different placement decisions, and one bad choice cascades through your whole build. Poki Games hosts the full campaign, so you can refine your layout and see how far a smarter stack will carry you.
