Gerrymandering Rules

  • Draw edges so that there are a number of areas (=orthogonally connected cells) of equal size.
  • Every cell belongs to an area.
  • The blue cells must win the most number of areas (no tie with another colour!).
  • A colour is said to win an area, if no other colour has more cells in that area.
  • An area may not have two colours that share the highest number of cells in that area.

Solve on Penpa+


Example for better understanding:

Solve on Penpa+

Solution code: The length of continuous cells in row 1 and 3.
In the example: 3131231

I have gotten used to examples being smaller and simpler than the main puzzle. On this one, they are about the same and it feels like we have been robbed of something, or been given too much hidden knowledge. Definitely a good concept for a puzzle.
