Logic Masters Deutschland e.V.

Rules: In the grid, water (blue) is flowing down some steps (grey) and into a vase (red). Each colour (red, blue, grey) contains one of the following groups of numbers: [1,2,3], [4,5,6], [7,8,9]. It’s up to you to find which group of numbers appears in which colour. Also, the vase is leaking, causing a mixture of red and blue cells (magenta) along the bottom of the grid.

1. Normal Sudoku rules apply

2. Numbers along thermometers increase from the bulb to the end

3. The number in the corner of a cage indicates the sum of all digits in the cage and digits may not repeat in a cage

4. Clues outside the grid show the sums of digits sandwiched between the 1 and 9 in that row/column

5. The circled cell at the end of the arrow is the sum of the digits on the arrow

Puzzle is also available on f-puzzles

Highlight the text between the brackets if having trouble finding the break-in. [
