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.
