#A4: Soulmates

 Unfortunately, I've only made one puzzle today, but at least it plays on the length-width theming and includes four twelves. I spent a few hours on two other theme-based puzzles but couldn't get them to work out. This genre does have lots of interesting logic, but it can be difficult to design at times because sometimes it feels like you need to get lucky for the shaded squares to resolve into numbers.

Rules and image added on 1/24/26:

Place some more numbers in the grid so that each number can only reach one other of the same value by travelling left, right, up, or down one space at a time without passing through other numbers, and the shortest path each can take equals the value of the number.
