Pin Pusher

Overview

The Pin Pusher pushes Pins under shapes received as input and outputs the result.

Specific Process

Firstly, pins are created under every non-empty shape part of the shape's bottom layer.

Spoiler warning : the next step is a solution for how to get pins without anything on top of them in a shape, you might prefer figuring out the solution by yourself first.

Then, any layers above the limit (5 if insane Scenario, 4 otherwise) get discarded. For Crystals in the layer that gets discarded, any that was directly above another crystal will make it shatter along with all other connected crystals.

Finally, the Shape Gravity Rules are applied to the resulting shape.
