I've always liked a good puzzle, something that pushes me to think differently. These Sudoku puzzles are definitely not your regular Sudokus. When you open one, you might see very few given digits, or sometimes none at all. What makes them so unique is that each puzzle comes with its own set of custom rules. Here are a few examples:

• Consecutive digits along lines or differences of 5 between digits along lines
• Sum of digits in a line equal to the value at the start of the line
• Digits inside cages summing to specific totals

It's fascinating how each puzzle feels like a completely new game, even though they share the same basic Sudoku structure. Unlike regular Sudokus, where you fall back on familiar patterns, these custom-rule puzzles force you to adapt and learn new strategies every time you play. Different combinations mean different challenges, and it never feels repetitive.

If you'd like to try them, here's a list of puzzles arranged from (what I believe are) the easier ones to the more challenging:
