Viper Valley Trail Map (Triple Snake Sudoku)

(Published on 20. March 2022, 04:43 by Nordy)

Another collaboration with my buddy Pokitchayng—this time with more snakes.

Assignment #2: Congratulations on completing your first assignment! For your next assignment, the trails at Viper Valley have recently been renovated and we need you to update our trail map. Three sets of trailheads have already been marked for you. Additionally, our surveyors have placed arrows on the trails showing the distance to the nearest outgrowth of trees. Use this information to complete a trail map of Viper Valley.

Rules:

Draw Three Trails:

  • Draw three 1-cell wide trails in the grid.
  • Each trail must not touch itself orthogonally, but may touch other trails.
  • Trails do not overlap, cross, or share cells.
  • The trailheads (ends) of each trail are given as a matching set of shapes (the two circles are the ends of one trail, for example).

Trail Sudoku:

  • Every row, column, and 10-cell region must contain the digits 1 to 8 and two trees. Trees occupy cells just like digits but have no value.
  • Trees must not be on a trail.

Arrows:

  • Digits in cells with arrows give the distance to the nearest tree in the corresponding direction. Distance is measured in cells and includes the cell with the arrow.
  • Cells with arrows must be on a trail.
  • All arrows may or may not be given.

Example: An example puzzle and solution are included for your reference. For the example puzzle, draw two trails and place the digits 1 to 4 and one tree per row, column, and region.

Here is the main puzzle. Good luck!

Solution code: Row 4 from left to right. Use "T" for both trees. Ex: 123T45T678
