This puzzle uses the Polyline ruleset, inspired by Neokart!

• Normal sudoku rules apply: Place the digits 1-9 once each in every row, column, and 3x3 box.
• Kropki: If two digits are separated by a black dot, one is double the other. If two digits are separated by a white dot, they are consecutive. Not all possible dots are given.
• Polyline: Box borders divide the gray line into segments, each of which must be a valid chess line for one and only one of the following types: Bishop, Knight, Rook, or King. Segments that are directly connected may not be the same type.
• Chess Lines: Adjacent digits along a segment must be related by the standard movement of that segment's assigned chess piece, imagining the 3x3 numpad as a subsection of a chessboard. For example, if a chess knight were on the 3 on the numpad, it could only move to the 4 or the 8, so a 3 would only be able to be adjacent to a 4 or an 8 on a knight segment. Digits that are adjacent on the line across a box border do not need to be related in any way. Chess pieces used in this puzzle move as listed below:
• Bishop: Moves any number of squares diagonally.
• Knight: Moves in an ‘L-shape,’ two squares in a straight direction, and then one square perpendicular to that.
• Rook: Moves any number of squares horizontally or vertically.
• King: Moves one square in any direction.
