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. Kojun: Every area consists of N fields. In every field is a figure from 1-N once each. Figures in horizontally and vertically neighboring fields must be different. Wherever fields in the same area are vertical neighbors, the upper figure must be higher than the figure below it.

B. Sumdoku: In every row and every column are the figures from 1-6 once each. The figures in each area must add up to the given number.

C. Kropki: In every row and every column are the figures from 1-6 once each. A black dot between two fields means that one figure is twice as high as the other figure. A white dot between two fields means that the difference between the two figures is exactly 1. If there is no dot between two fields, none of the last two rules applies!

D. Renkatsu: The puzzle has to be divided into areas consisting of N fields (N can be every size from 1 - 5). Every area with size N must include all figures from 1 - N.
