Sudoku Corner/Edge
(Published on 19. January 2022, 15:36 by ropeko)
Rules
Apply classic sudoku rules.
Hints outside the grid represent digits of corner (C) and edge (E) cells of the corresponding 3x3 box. I.e. C:12 means that the digits 1 and 2 must be in one of the four corner cells of the 3x3 box. E:12 for one of the four edge cells.
Background/Inspiration I looked at the instruction booklet of the first Sudoku GP round of this year and thought that the Corner/Edge variant could be combined rather good with Phistomefel's ring.

Jede Box hat 4 Corner (Ecken) Zellen.
Jede Box hat aber 8 Rand (Edge) Zellen oder sind von diesen Zellen die Corner(Ecken) ausgenommen?
