Harbor Haul: Crane Stacking

Harbor Haul is a one-thumb crane stacking game. The trolley sweeps back and forth on its own; you pick the moment to tap and drop the hanging cargo onto a barge. Real physics decides whether it stays.

Every crate behaves differently: glass cracks if you stack steel on it, barrels roll a moment before they settle, sacks stick where they land, and some pieces bounce. Rotate a crate before dropping, keep the heavy ones low, and read the swell before it reaches the barge.

Take contracts: 40 short harbor jobs across 5 ports, each over in about half a minute with three star goals. A new port brings a new physical rule such as wind, ice or a rolling swell. Earn coins for 5 upgrades and 16 cosmetics. A Daily Contract gives everyone the same cargo, and Free Stack lets you go as high as you dare.

About ads: the game is free and supported by ads. A rewarded ad plays only when you tap a bonus button (an extra crate, a steadier hook, double coins), and the game progresses the same if you never watch one. An interstitial ad may appear between contracts (never in your first session or the first 15 minutes). There are no ads during a contract, no banners and no in-app purchases.

No account needed; progress is saved on your device. Available in Korean, English, Japanese, Simplified and Traditional Chinese, Spanish, Portuguese (Brazil), German, French, Indonesian, Thai and Vietnamese.
The harbor backgrounds, app icon and store artwork were generated with generative AI (Google Gemini), then selected and edited. Crates, cranes and the interface are drawn in code.
