Rules:

Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.

Shifter lines: Adjacent digits within the same box on a shifter line share both parity (even/odd) AND polarity (low/high). Whenever the line enters a new box either the parity OR the polarity shifts, never both. Shifter lines can never have 5 on it. Digits may repeat on lines.

Kropki dots: A black dot between cells indicates cell values with a 2:1 ratio. Not all dots are shown.

X: Adjacent cells connected with an X must sum to 10. Not all X's are shown.

Search 5: Each arrow points to the closest 5, where the digit on the arrow is how many cells away the 5 is. For example, lets say there's an arrow in R1C1 pointing to the right. If R1C1 was a 1, R1C2 would have to be 5. If R1C1 was 8, the 5 would have to be in R1C9. There may be multiple arrows pointing to the same 5, and it's not necessary for every 5 to have an arrow pointing to it. If R7C7 was a 6, there would have to be a 5 in both R1C7 and R7C1.

There is a setting (under Visual) called 'Draw Arrows Above Lines', and I'd recommend you set that to 'On'.
