Attention: Again this time, NONE of the puzzles can be solved without the help of the other puzzles. In every puzzle are 3 colored fields. Same colors mean same figures. Standard rules of every puzzle type apply:

A. 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.

B: Meandering (winding) Numbers: Enter one figure in each field. Every region of N cells contains each number from 1 to N exactly once. Within each region, each figure has to touch its natural neighbors orthogonally (like a "number snake" from 1-N; Example: the 2 must touch the 1 and the 3 orthogonally). Same figures may not be adjacent, not even diagonally.

C: Renban: In every row and every column are the figures from 1 - 8 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).

D: Chaos Sudoku: In every row, every column and every separated area are the figures from 1 - 8 once each.
