Snake in the Grass
The brief
- Normal 6x6 sudoku rules apply.
- Draw a snake, one cell wide, that starts and ends at two neighbouring cells, only moves orthogonally, and visits every cell in the grid without crossing itself.
- The snake must eat every insect, but must not pass through any grey pebbles.
- Insects divide the snake into segments.
- Adjacent segments along the snake have consecutive totals. No two segments have the same total.
- Digits joined by a grey pebble are either consecutive, or have a 1:2 ratio.
