Normal sudoku rules apply. The digit on the eyeball (Red Circle) must be even. The digit on the silver circle must be odd. Digits along the grey thermometer must increase from bulb to tip. Adjacent digits along the green line (r3c4 to r2c6) must differ by at least 5. Digits separated by a black dot are in a 1:2 ratio. Digits separated by a white dot are consecutive. The corner white circles contain digits that must be placed in the four cells connected to that corner. The black lines are region sum lines, for which digits on the line have an equal sum within each box it passes through. Pointing numbers outside of the sudoku puzzle point to a diagonal on which the digits must sum to the number given. Digits along the purple renban line must, when placed in an ordered list, be consecutive. Adjacent digits do not have to be consecutive on these lines, however.
