Normal sudoku rules apply.

Thermo: Digits on a thermo increase from the bulb end.

Loops: There are several "loops" in the grid. A loop is a piece of line with its ends connected. Two loops may share an edge. A loop cannot cross itself and it cannot contain any piece of line in its interior. For example, if the line was in the shape of the number 8, then this would be two loops that share a piece of line. There is no loop going around the outside of the figure 8.

Cycles: On each loop, there is a set of circles called a "cycle". Each cycle has a starting circle. On each cycle, the digits in the circles must increase starting at the starting circle and traversing the loop either clockwise or counter-clockwise. The starting circle and polarity (clockwise or counter-clockwise) must be determined by the solver. Digits on a loop that are not in a circle are unaffected by the loop.
