"Tower Siege" Game

In Tower Siege, you stack blocks into a tower and then protect it from attackers. After each wave, you draw a hand of four shapes — walls, archers, cannons, mortars, and tesla coils — and get a little time to set them down. Then the enemy horde charges in: goblins, boar-beasts, burning hounds, bone knights, and siege engines that shoot farther than anything you have. If a block loses its support, it tumbles down, and the falling rubble smashes whatever sits below it. Spend your wood, stone, and gold wisely, unlock new tech tree upgrades, and find out how deep you can go!
