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.
