What is distinct here
Harbor Handoff combines one-button timing with a visible three-stop delivery order. The route must be read before acting, and every completed manifest reverses the crane while increasing speed, so attention must shift between planning and timing rather than repeating one rhythm.
Rules
- Each shift contains four fixed, verified manifests. Every manifest lists three different docks that must receive crates in the displayed order.
- The crane rotates continuously. Press the handoff control only when its crate enters the highlighted target ring; the narrower center window scores a perfect handoff.
- A mistimed press keeps the same target but uses one of three signals. Completing a manifest adds a delivery bonus, reverses direction and increases crane speed.
- Complete all twelve ordered handoffs to win. Score rewards accuracy and consecutive clean stops; the best completed score stays only in this browser.
Strategy tips
- Read all three dock symbols before the crane starts a manifest. Planning the order prevents you from chasing whichever ring happens to be nearest.
- The amber ring is a safe handoff, while the narrow green center window earns a perfect bonus. Secure the route first, then tighten your timing.
- Every completed manifest reverses rotation and raises speed. Reset your visual rhythm at the first stop instead of pressing on the old cadence.
What we tested
Four deterministic manifests contain no adjacent duplicate docks and the rotating crane necessarily reaches every target. Tests cover wraparound angle distance, safe and perfect windows, three-signal failure, scoring, direction changes, increasing speed, pause and the complete twelve-stop win path.
Frequently asked questions
Can Harbor Handoff create a random impossible route?
No. All four manifests are deterministic, contain no adjacent duplicate dock, and every target is reached by the continuously rotating crane. Automated tests complete all twelve stops.
Do I need rhythm-game experience?
No. The requested dock stays visible, its large ring lights up, and the action readout changes from wait to safe and perfect. The first manifest also uses the slowest speed.
Does Harbor Handoff upload my timing or score?
No. The active shift stays in the current session, and only the best completed score is stored locally in this browser.
