Ice Harbor
Plan the stopping point on the ice
Ice Harbor asks a penguin to deliver crates through twenty sliding puzzles. The important question is where a move stops, not only where it begins. A crate passing through a useful square is different from being able to leave it there. Read the route and any blocking surfaces before pushing it into a long slide.
Keep access to the side of the crate needed for its final delivery. Solving a short segment can still block the path required to push from another direction. Work backward from the destination and check the penguin’s route separately from the crate’s route.
Use hints and undo for understanding
Undo lets you compare one earlier decision without rebuilding the whole attempt. A hint is most useful when you can explain what uncertainty it resolves. Pause to identify the changed stopping point or access route instead of immediately repeating the suggested input without reading it.
No timing claim is attached to the campaign here. On a touch device, use the current game controls and allow the slide to finish before interpreting the next state. Include the level and final crate position when reporting a problem; the full board is important to understand the stopping rules.
