Tap a vessel to sail it to a free dock. Crew walk round the quay and board the boat of their colour; a full boat departs and frees its dock. If every dock fills with no one able to board, the harbour runs aground: use a rescue, a booster, or try again. Each new mechanic has a short demo the first time you meet it, and you can replay them all from the ? button on the map.
Yes. Every level is generated and then proven solvable before it ships, so there is always a way through without boosters.
Each board ranks your ranked time: the clock plus a penalty for each booster or rescue used. Level boards keep the fastest 1,000 players. The Daily ranks your best on-time play; weekly and monthly boards rank the days you played, then your total time.
Your progress syncs automatically while you are online. To keep it across devices or after a reinstall, use Settings → Link Account to sign in with Game Center on each device.
No. From level 10 you can choose to watch a short video for a reward, such as double coins or a rescue. Rescues, boosters and the Berth Permit can always be bought with coins instead, and the ads are never personalised.
Settings → Reset Progress starts the game again. Settings → Delete account removes your account, progress and board times from our servers and starts the app as a new player. You can also email support@ahm-technology.com and we will delete it for you.
