Nulldoku

The Nulldoku series introduces a fresh take on classic logic puzzles by reimagining Sudoku with one elegant twist — zero.
Rows and columns are split into segments by zeros, and each segment must contain non-repeating digits forming a consecutive sequence.

With puzzle sizes ranging from 7×7 to 12×12, the Nulldoku series offers a carefully balanced mix of relaxing and challenging puzzles, designed for pure logical solving without guessing.

Perfect for puzzle enthusiasts looking for something familiar yet completely new.
