About Tower Siege

Tower Siege is a free online arcade game you can play right here in your browser. Build a tower out of the blocks you are dealt, then defend it. Between waves you get a hand of four shapes — walls, archers, cannons, mortars, tesla coils — and a short window to place them. Then the horde arrives: goblins, boar-beasts, burning hounds, bone knights and siege engines that out-range everything you own. Blocks that lose their support fall, and falling rubble crushes whatever is underneath. Spend wood, stone and gold, unlock the tech tree, and see how deep you can get.
