Three is a crowd
Inspiration for this type comes from Sudoku GP 2013 (Italian round).
Solve online in Penpa+ (thx Nick Smirnov!)
Place the digits from 1 to 9 once in every row, column and 3x3-block. Clues outside the grid show the three numbers that have to be placed in the first three cells from that side. However, exactly one digit of each triplet is wrong. On each side of the grid (top, bottom, left, right) all of the wrong clues are different.
Solution code: Row 5, followed by column 5.

Finde das Rätsel auch extrem geschmeidig. Für meinen Geschmack sind aber deutlich schwierigere Rätsel schon mit zwei Sternen durchgegangen.
