Here is a new one. This one might be more difficult, at least to start.
What’s My Line
Normal sudoku rules apply.
Diagonals: each of the main diagonals must contain all of the digits 1 to 9.
Between line: all digits on the line must have values strictly between the values of the circles at the ends of the line.
Thermometer: values of cells on the thermometer are strictly increasing from the bulb end.
German whispers line (brown): consecutive cells along the line must have a difference of at least 5.
Renban line (purple): cells on this line have values that form a set of consecutive numbers, in any order.
Palindrome line (grey): cells equidistant from the middle must have the same value eg 146641.
Anti-palindrome line (green): cells equidistant from the middle must have values which sum to 10. Equivalently, cells equidistant from opposite ends must sum to 10. eg 421986.
