Normal sudoku rules apply. Place the digits 1-6 once each in every row, column, and 2x3 box.
Palindrome: digits along a grey line read the same forwards and backwards.
Kropki: digits separated by a white dot are consecutive; digits separated by a black dot are in a 1:2 ratio (i.e. one digit is double the other). Not all dots are necessarily given.
Solve in VariantDoku (iOS, macOS, Android) or on SudokuPad.
Solution code: Enter the digits of column 1.
