* After the shift on 23 December the miners of the Erzgebirge celebrated in their mines the Mettenschicht. Still today many christmas hootenannys take place underground in former mines. For me they are among the most beautiful. Our miner is facing the following puzzle: *

The letters A, B, C and D represent four minerals that are hidden in a gallery. Write the letters A, B, C and D) in some fields of the grid. Each letter must occur in each row and each column exactly once. The remaining fields are blank. Letters outside the diagram indicate which letter you see if you look into the grid from that point. Numbers in the grid indicate how many letters are on the 8 neighboring cells. Cells marked with a number are empty.

This puzzle raises a view at a pyramid in Carlsfeld, which faces the Trinity church. Carlsfeld is located directly on the ridge of the Erzgebirge and a popular entry point for cross-country skiing. But our puzzle not only shows a view on this pyramid, but also even and odd views.

Fill in the grid with the numbers 1 to 6. In each row and each column, each number occurs exactly once. The even numbers in the margins indicate which is the first even number in the corresponding row. The odd numbers indicate which is the first odd number.

Fill the grid with the digits 1 to 6. Each row, column and 3x3-box has exactly one of each digit and 3 empty cells. The clues along the edges tell you which digit you can see from that vantage point.

Fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 through 9. The even clues along the edges tell you which digit is the first even digit from that vantage point. The odd clues along the edges tell you which digit is the first odd digit from that vantage point.

Fill the grid with the letters A, B, C and D. Each row and column has exactly one of each letter and two empty cells. The clues along the edges tell you which first letter you can see from that vantage point. Letters with a red cross say that you can't see this letter as first.

Fill the grid with the letters A, B, C, D and E. Each row and column has exactly one of each letter and an empty cell. The clues along the edges tell you which position you can see the letter from that vantage point.
