Normal sudoku rules apply.

The central 3x3 box is a magic square, meaning that each row, column, and main diagonal adds up to the same number.

Exactly one other 3x3 box in the grid is a magic square (must be determined by the solver).

Digits along the grey 'Between line' must lie in between the digits on the circled ends of said line.

Yellow lines are 'Sequence lines' that contain digits in order with a constant difference (1-2-3, 2-5-8, 3-3-3, etc).
