Buoy

The game

Buoy is a harbour loadmaster puzzler: drag crates, anchors and barrels onto a flat barge and make its draft match the green depth-mark on every pier. Bridges need you light, locks need you exact — misjudge either and the hull smashes the span or scrapes the lock gate. The spring-driven buoyancy sim makes the hull bob, settle and list with every item you stow, and the porthole gauge shows the draft needle against the next band in real time. Fewer loads for the same depth means a better star score, so plan the stow, not just the weight.

How to play

• Drag barrels, crates and anchors from the DOCK STOCK panel onto the barge deck — items stack, and the weight list on the panel shows what each costs you.
• Watch the porthole draft gauge: the orange needle must sit inside the green band of the next gate — 8 px under a low bridge, or dead-centre on a lock depth.
• Press Enter (or click CAST OFF) to cast off and sail; keep going through every gate until the harbour flag.
• While sailing, click cargo on deck to jettison it overboard and rise before the next band.
• Deck trim matters too: pile everything to one side and the barge lists, then capsizes. Clear all 8 runs — fewer loads earns up to 3 stars per run.
• Press P to pause, R to retry the current run.
