Logic Masters Deutschland e.V.

Normal Sudoku rules apply.

The grid represents a water park containing several water slides, which must be deduced. Each water slide is a non-branching path of at least two orthogonally or diagonally adjacent cells. Slides may turn by at most 90° at each cell and may cross themselves or each other. Every cell lies on exactly one water slide, every water slide starts at a star, and every star marks the start of a water slide.

Digits on a water slide may decrease or stay the same from start to end, but never increase. Adjacent digits along a water slide may differ by at most 2.

Digits on an arrow sum to the digit in its attached circle. Each complete arrow, including its circle, lies along a single water slide and points down the slide.

Cells with squares must contain even digits.
