(Published on 29. April 2024, 07:56 by Die Hard)

Introduction

This is the first of three puzzles using this rule set.

Rules

Normal sudoku rules apply. Place one (and only one) "renbanomino" (an orthogonally connected group of shaded cells that contains a consecutive set of digits, where one of the shaded digits is circled and indicates its size) in each of the 9 sudoku boxes such that across the entire grid:

  • All shaded cells are orthogonally connected.
  • All unshaded cells are orthogonally connected.
  • No 2x2 region contains all shaded or all unshaded cells.

Really enjoying this series. I found this one to be a bit trickier than Yin-Yang Renbanominos
