Normal sudoku rules apply. Place the digits 1-6 once each in every row, column, and 2x3 box.
Thermometer: digits must strictly increase along each thermometer, starting from the bulb.
Equal-sum (blue) lines: box-bounded segments of each blue line have the same total.
Palindrome: digits along a grey line read the same forwards and backwards.
Lockout line: the two diamonds hold different digits, and every digit on the line between them is strictly outside the range spanned by the diamonds.
Cells connected by an X sum to 10. Cells connected by a V sum to 5. Not all Xs and Vs are given.
Digits may not repeat along marked diagonals.
Solve in VariantDoku (iOS, macOS, Android) or on SudokuPad.
Solution code: Enter the digits of row 2.
