Normal sudoku rules apply.

Pie Slices: Each of the 13 lines must contain a contiguous slice of the first 50 digits of Pi. Together, the 13 lines contain exactly 50 digits, and when their contents are concatenated in order, they reproduce the first 50 digits of Pi without gaps or overlaps.

Pie is Better Than Cake: The central cell (r5c5) is a cake cell. Whatever digit appears there is treated as 0 solely for determining the Pi slices.
