Sudoku-Like Puzzles
The main difference between Sudoku and Sudoku-like puzzles is the absence of additional blocks. In standard Sudoku, the 9×9 grid is divided into nine 3×3 blocks, each containing the numbers 1–9 without repetition.
Sudoku-like puzzles, however, lack these additional blocks but have different rules or constraints.

The number of puzzles of this type is small, so we have limited ourselves to sorting them alphabetically and do not plan to divide them into groups.
