ADDITIONAL INFORMATION
Comment 1 Ian Wadham 2019-02-25 21:15:22 UTC 
In Killer Sudoku the rules for Classic Sudoku apply. The columns and rows of the solution must contain the digits 1 to 9, but so must the nine 3x3 grids in the puzzle. In your attachment, the 3x3 grid in the top left of the 9x9 puzzle contains two 4s and has no 6, so it is marked as an error. Similarly for the other three cells that are marked in red.

Unfortunately the 3x3 grids on a Killer Sudoku are not marked, because I could not work out how to do that without cluttering the graphics. You can see them if you print your puzzle.
