Normal Sudoku rules apply.
Cover the grid with
four each of the five free tetrominoes (I, L/J, S/Z, T, O). Tetrominoes of the same shape must not touch each other, not even diagonally.
Every tetromino acts as a
killer cage: digits must not repeat within a shape.
The
sum of the digits in each tetromino
is the same throughout the puzzle.
The pink lines are
renban lines: they contain a set of consecutive numbers in any order. Cells connected by a line belong to the same tetromino.
The marked cells in the top right box are special: one of them is
not part of any tetromino, the other one
contains the largest digit of it's tetromino.
Which one is which needs to be determined by the solver.
Tip: it's possible to determine most of the shapes just by using the lines, but it's really tedious. It's better to solve for numbers and build the shapes in parallel.

Very interesting ruleset! It was slow going for me in the beginning but it was well worth the time spent by the end. The latter half especially was a ton of fun. Thanks Matyas! :)
