Normal sudoku rules apply. However, every clue is lying to you! The thermometer bulb is not where it says it is (but is still on the thermo, and each thermo cannot contain a repeated digit). Killer cages don't sum to the number in the corner. Little killer arrows do not give the sum of cells on their diagonal. X and V clues mean the adjoining cells don't add to 10 or 5 respectively. The palindrome line does not contain a palindrome. Black kropki dots mean neither adjoining cell is half of the other. Maximum cells (in blue) are not greater than all four adjacent cells.; Cells touching “quadruple circles” do not include all digits within the circle (but may include some of them).
