Puzzle 375: Rugged terrain

This is a new puzzle style.


Rules: Some numbered Range rovers are placed in the grid. The objective is to drive each car as many cells as the number written in the cell, moving only horizontally or vertically. Shaded cells represent blocks of water. When a car enters water, it has to travel the entire block before leaving. Every cell is visited by exactly one car.

  1. As far as I can tell, there are no solutions to this. Unless of course, I'm misunderstanding the rules.

  2. I will wait until someone proves it is solvable or not. At least, the total sum of all clues appears to allow for a solution.

  3. I may be misunderstanding the rules myself, but I'm getting two solutions, with the upper four and the ten switching paths. See here: http://imgur.com/a/91qT5

  4. Yes, you probably didn't understand the rules. I couldn't have described the rule with water blocks in a better way. Obviously, only one car can traverse a water block.

  5. Is this closer to the rules you intended? http://imgur.com/a/rywq7

    1. Right, but I had missed that bunch. I have added a water block at R4C1-2 for uniqueness.
