Logic Masters Deutschland e.V.

Sudoku: Normal Sudoku rules apply.

Kropki: Digits in cells separated by a white dot are consecutive. Digits in cells separated by a black dot have a 1:2 ratio.

Odd Arrows: Digits in a cell containing an arrow count the number of odd digits in the chosen direction, not including the arrow digit itself.

Snake: Starting from the green circle in R1C1 draw a snake, a one cell wide series of orthogonally connected cells that does not branch or touch itself, not even diagonally.

The snake must enter each box at least once, and the snakes tail position must be determined by the solver.

Every digit along the snake must be odd, and every digit orthogonally adjacent to the snake must be even.
