Rebound Bastion
Return four cannonballs into the four enemy turrets. The three-panel bastion slides left and right; the glowing forecast column shows where the next ball will arrive. The outer panels can each take ONE hit, while the center can take TWO. Damage stays with a panel when you move it. Set the rebound slope left or right before releasing a volley. Returned balls travel three rows upward, reflecting off side walls, then strike the turret row. Destroy turrets at columns 1, 2, 4 and 5 in four volleys. Catching with a broken panel loses; hitting an empty turret wastes that volley. Use the center panel for the first two arrivals so the edges survive the last pair.
