A: 2D-Sudoku: In every row, every column and in both long diagonals are the figures from 1 - 6 once each.
B: Renban: In every row and every column are the figures from 1 - 6 once each. The figures in an area must be unique and must form a sequence without gaps (e.g. 3,4,5,6), but not necessarily in the natural order (e.g. 4635 is allowed).
C: Hakyuu: In every field is a figure. In every area with N fields are all figures from 1 – N once each. If there's a figure X more than once in a row or column, then there must be at least X fields with other figures between these fields.
D: Brick Wall: In every row and every column are the figures from 1 - 6 once each. In every brick is one odd number and one even number. The half-bricks on the left and right side of every second row form a complete brick together.

Love your puzzles! Question: Am I misunderstanding the rules for Hakyuu? The solutions on Penpa and Sudokupad, row 4, have two 2's with only one field between them. I though there needed to be two fields between 2's.

that's strange. In my solution, there are not two 2's close to each other in row 4. You understood the Hakyuu rules correctly
