Lumen Dock · 120-stage campaign

Lumen Dock in Little Sunlit Harbor: 120 fixed sequential stages with on-device progress.

Play when ready. No stage is created or played before Start.

Lumen Dock · Goal & controls

1. Cargo slides only along its long side. Guide the amber boat to the right-hand exit without overlap or jumping.
2. Consecutive adjustments of the same block are one turn, whether using buttons, keys or dragging. A different block must actually move to start the next turn.
3. Undo restores a whole turn. Solution practice replays the certified path on a cloned board without changing your live game or unlocks.

First-stage goal

Guide the target boat to the right edge of row 3.

First-stage example: star criteria

1. Finish within 1 block turns for 3 stars, within 3 for 2, or otherwise for 1. Hints and undo do not reduce stars; consecutive adjustments of one block share a turn.
2. Every genuine clear unlocks the next stage. Stars never block progress.

Review each stage goal and grade before Start. Proof practice never changes live progress or records. Previous free/daily records are not converted into stage progress.
