Normal Sudoku Rules apply.

A cycle is where you start at a position, then go to the position of that value, and repeat until you get back to the beginning. The length of a cycle is how many values are visited before returning to the start. On a line, all cycles must be of length 3, with position 1 as the circle on one end and counting up as the line progresses. In addition, digits cannot repeat, and must be between 1 and n, where n is the length of the line.

Examples of cycles: a valid cycle would be 312, as the 3 on the first value goes to 2, the third value, to 1, then back to the first position, with length 3 because 3 distinct cells were visited. 312645 would also be valid, as there are two cycles of length 3. 312465 would not be valid, however, as there is a sequence of length 2 (6 to 5) and 1 (4), not length 3. Note the sequences can be interlocked such as 461325, which is a valid 3 cycle line.

Digits separated by an x sum to 10

Digits separated by a white dot are consecutive.
