Story
Build a castle. Knock theirs down. Repeat until you rule the world. Castle Stacker is a real-time siege game where your fortress falls from the sky one room at a time. Pick a card, line it up, drop it: a cannon here, a barracks there, a treasury tucked safely behind a rampart. Fill a whole row and the coffers ring with gold. Leave a gap and you'll be patching it under fire. You don't fire the guns yourself. Your little people do. Bombardiers man the cannons, artificers scramble up ladders to mend cracked walls, guards hold the stairs, and soldiers gear up at the armoury and charge across no-man's-land. They're all after one man: the enemy king, who sits in his throne room and fights like two. Bring him down and his whole castle follows, room by room, in glorious slow motion. A fortress is a puzzle with cannons in it - Mage towers fire arcane bolts, ward stones raise shields, and storm spires chain lightning through raiders and balloons. - Hot-air balloons drift overhead dropping trouble, mortar pits lob shells over the walls, and gargoyles guard your battlements. - Bolt on drawbridges, crow's nests and grappling lines, then send your soldiers sliding straight into the...
