One of the puzzles can be solved without the help of the other puzzles. In each puzzle are 2 colored fields. Same colors mean same figures. The standard rules of every puzzle type apply (don't read if you know them).

A: 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).

B: 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.

C: Chaos Sudoku: In every row, every column and every separated area are the figures from 1 - 6 once each.

D: Consecutive: In every row and every column are the figures from 1 - 6 once each. The difference between two figures linked with a white dot must be 1. The difference between other neighboring cells can not be 1.
