Tower Siege

Tower Siege is a tower defense game in which you build a tower from the blocks you are dealt, then defend it. Between waves you get a hand of four shapes, including walls, archers, cannons, mortars, and tesla coils, along with 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.

A short window separates the waves, and in that window you place the hand of four shapes you were dealt, among them walls, archers, cannons, mortars, and tesla coils. Blocks that lose their support fall, and the falling rubble crushes whatever is underneath. Wood, stone, and gold are yours to spend, and the tech tree can be unlocked as you see how deep you can get.
