Castle Stacker

Build a siege castle

Castle Stacker is a real-time siege game for PC where you build a fortress room by room and try to bring down the enemy castle. You pick a room card, line it up and drop it into your structure. Cannons and barracks need placement alongside treasuries, ramparts and other rooms: fill a whole row and it earns gold, while gaps leave the castle needing repairs under fire.

You don’t aim or fire the guns yourself. Bombardiers operate cannons, artificers climb ladders to fix cracked walls, guards hold stairs and soldiers arm at the armoury before charging across no-man’s-land. The enemy king sits in his throne room and fights like two. Defeat him and his castle collapses room by room.
