Logic Masters Deutschland e.V.

Rules:

• Fill each hexagonal cell with a digit 1-7, such that no digits repeat on any of the 3 axes or in the 7-cell regions.
• Thermometers: Digits must increase along a thermometer, starting at the bulb end.
• Arrows: Digits along an arrow must sum to the digit in that arrow's circle.

Note: There are 15 lines of length 7 within the puzzle, 5 on each axis. For your convenience, these are marked with dashed lines on the ends. On lines with fewer than 7 cells, digits still may not repeat.
