This is a Liar Yajisan-Kazusan puzzle.
The rules for Yajisan-Kazusan can be found here: Rules page
In addition to the usual rules of Yajisan-Kazusan, one clue in every row and every column is mislabelled. If this clue is unshaded, then it does not point to the number of black squares indicated. If it is shaded, then it provides no information.
This was the first puzzle I ever created. Wanting to create this variant was what got me into creating puzzles in the first place; I hope you enjoy it.
