Here’s a walkthrough for Freddie’s Juosan: https://youtu.be/VPi7x404S7I

Welcome to GAPP Boomerang practice! 🪃 Today, we’re going to be throwing your familiar two-wing, V-shaped sport boomerangs (though do check out long-distance boomerangs, which can be question mark-shaped!). When throwing, make sure to hold it vertically, not horizontally. And do you know why it comes back? The two sides of the boomerang are aerofoils, and generate lift like the wings of a plane. When the boomerang spins, the top wing generates more lift because it’s spinning in the same direction as the flow. The lower wing is moving against the direction of the throw, and generates less lift. This difference in lift creates a rotational force, causing the boomerang’s path to curve! (A bonus otter 🦦 to anyone who can explain why the boomerang doesn’t just tilt around the direction it’s flying - I spent about an hour reading about gyroscopic precession and still can’t explain why 😅). Oh, and make sure to return all your boomerangs to this hexagonal crate when you’re done! If you line them up with the dots, they should fit together nicely.

Rules: Divide the grid into "boomerangs", each containing exactly one dot. A "boomerang" consists of a center cell and two legs of equal length coming off the center cell at a 120-degree angle. Each cell in the grid must be part of exactly one boomerang. The legs must be of length at least 1.

Interface Note: I've defaulted to edgesub, but feel free to use line (or linex) if you prefer it! Answer check should work for either edges or lines.
