This puzzle was inspired by MattYDdraig!
Rules:- Normal sudoku rules apply: Place the digits 1-9 once each in every row, column, and 3x3 box.
- Two truths and a lie: For each of the following clue types there are 3 examples in (or around) the grid. Two are true and must comply with the rules, but one is a lie and must not comply.
- Region Sum Lines: Box borders divide hollow blue lines into segments with equal sums. Different lines may have different sums.
- Kropki: A black dot between two cells indicates that one digit is double the other. A white dot between two cells indicates that the digits are consecutive.
- X-Sums: Red numbers in squares to the left of the grid show the sum of the first X digits in the row, where X is the digit in column 1.
- Little Killer: Numbers in black with arrows below the grid show the sum of the digits along the indicated diagonal.
- Sandwich: Blue numbers in circles to the right of the grid show the sum of the digits between the 1 and the 9 in that row.
- German Whispers: Adjacent digits on a thick green line must differ by at least 5.
- Renban: Digits on a pink line form a non-repeating consecutive set in any order.
- Thermometers: Digits on a thermometer strictly increase from bulb to tip.

Wonderful idea. I appreciate it can be solved strictly logically.

Very neat construction. Agree with rameshsrivats, that I would put it closer to 3*, which is rare for a liar puzzle.

Great puzzle. Fun all the way. But closer to 3* difficulty, I think.
