A very easy puzzle. No challenging deductions required, almost an auto fill-in. A nice way to start my day, though.

A nice first puzzle. I am not sure why some of the dots were colored in SudokuPad, but they work just like the normal uncolored dots

Ah but what do the yellow "2" dots mean on the sudokupad page mean? ;)

I don't know where the 4-star difficulty rating comes from. I’m certainly just an average player and I wouldn’t rate it higher than 1 star. The break-in is easy to find even for beginners and after that, practically everything is forced and the puzzle solves itself.

Fixed a misplaced "Difference of 2" white dot between R4C7 and R4C8. The grid layout and the rule description have been updated accordingly. Sorry for any confusion!

The puzzle behind the sudokupad link has obviously no solution. Even if you delete the killer cages.

Updated the description formatting and replaced the grid image to improve clarity and preview quality. The puzzle logic and rules remain exactly the same!
