Logic Masters Deutschland e.V.

One of the puzzles can be solved without the help of the others. In every puzzle are 2 colored fields. In fields with the same color are the same numbers.

Standard rules apply (so don't read on if you know them).

A. Thermo-Sudoku: In every row and every column are the figures from 1 - 6 once each. In the grey „thermometers“ the figures are rising, starting from the bulb. The fields which are connected with a circle show the difference (-4) respectively the distance (delta/triangle 4) of the two figures.

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. Brick Wall: In every row and every column are the figures from 1 – 6 once each. In every brick must be one odd figure and one even figure. The two half bricks on the left and right sides of some rows form a complete brick.

D. Sukoro: In some fields are figures (from 1 – 4). A figure in a field indicates how many fields with figures are horizontally and vertically adjacent to this field. Same figures can’t touch each other horizontally / vertically. All fields with figures form a single (horizontally / vertically) connected area.

PS: I accept your suggestions for the 4 kinds of puzzles of the fifth upcoming 4x6x6 experiment.
