Fourwall Courtyard

Build every wall to exactly 6 stones. Incoming bundles cycle 2,1,1,2,1,2. A wall may stand at most 3 stones above either neighbor, so raise the courtyard evenly. The opposite wall locks after a placement. Overfilling collapses a wall; sealed walls are protected.

Choose a wall for the incoming bundle. Keep neighboring walls balanced.
