Harbor Cargo Logic

Harbor Cargo Logic is a turn-based top-down port and warehouse crate-pushing puzzle game by PT INDO SUNG-IL JAYA. Guide the harbor loader cart across compact square dock grids and push every shipping container onto its marked target cargo bay.

DESIGNED FOR CLEAR DETERMINISTIC LOGIC
Every stage uses classic, predictable grid movement rules on 6x6, 7x7, and 8x8 harbor boards:
• Move the loader cart one square Up, Down, Left, or Right.
• Push one shipping container forward by one square when the cell beyond it is open floor or a target bay.
• Plan carefully around concrete bulkheads and corners: containers cannot be pulled backward, and two containers cannot be pushed at once.
• Target bay beacons remain visible beneath docked containers so you can always read the board state at a glance.

24 HANDCRAFTED STAGES IN 3 PORT GROUPS
Progress through three themed groups of eight stages:
1. Coastal Pier (Stages 1–8): Introductory 6x6 and 7x7 dock layouts teaching corner turns, pillar routing, and narrow gates.
2. Container Terminal (Stages 9–16): Intermediate three-container warehouse yards requiring careful lane clearing and order of operations.
3. Deepwater Berth (Stages 17–24): Four-container harbor puzzles featuring central channels, lock chambers, and seawall depots.
