How to play
How do you play Renzoku?
Fill every cell with a digit 1..N (where N is the grid size). The rule: if two same-digit cells are orthogonally adjacent, they must be part of the same connected run, and that run's length must equal the digit. So a run of three 3s must be exactly three orthogonally connected cells; isolated 1s are valid singletons; etc.
