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.
You will die a lot, and that is the design. Arcade games expect it. Each run lasts until a single mistake, and then you are back at the start with a slightly better sense of the timing. Over a session of fifteen minutes you might play twenty rounds. Somewhere in the middle one of them goes well, and the number at the top of the screen jumps.
Tower Siege is honest. There are no upgrades to buy and no grind, just you and your reaction time. Because it runs free in a browser tab, it is the sort of game you can open on a whim, play for five minutes, and leave without a trace.
Players who miss the directness of old cabinet games, and younger ones who have never seen a cabinet but like a dare. It suits phones well, so it is handy for anyone waiting in a queue.
