How the daily chart works

Each UTC day gets one 7×8 harbor chart. Draw a single continuous tide and visit the numbered buoys in order from 1 to the last mark. Pick Easy or Hard before you seal the chart.

Modes

• Easy — reach every buoy in order. Empty squares can stay empty.
• Hard — hit every buoy in order and fill all 56 cells.

Objective

The coral ring marks the next buoy you still need. In Easy mode the chart seals when the last buoy is logged. In Hard mode you also need every square under the tide.

Controls

• Press buoy 1 to start the tide, then drag through adjacent squares
• Drag backward or tap an earlier square to rewind the path
• Hint snaps you onto today's charted route one step at a time
• Clear empties the line; Reset also clears time and hints

Tips

• Leave corridors open toward the next buoy before you fill side pockets
• If you wall yourself in, rewind a few cells instead of clearing the whole chart
