The wording isn't good. The number does not indicate how many jumps you need to make. It indicates how far you need to jump.

Otherwise fun!

I love the concept. I was left wanting more because larger puzzles are apparently not more difficult, they just seem to have a lot of solutions. But can we make them more difficult? Just in case anyone else wants more of a challenge... I hand-wrote a 10x10 that should be harder to crack:

    1  2  1  2  2  3  1  1  2  2
    3  2  3  3  3  3  3  3  3  3
    3  3  3  3  3  3  3  3  3  3
    2  1  2  2  3  2  1  1  3  1
    2  1  3  3  1  3  3  1  3  1
    3  3  1  3  3  3  3  3  3  3
    2  3  2  2  2  2  1  2  2  3
    3  3  3  3  1  3  3  1  3  2
    1  3  2  3  3  3  3  3  3  3
    2  1  3  3  2  2  2  2  1  F
Unless I made a mistake, the simplest solution is not easy to find. Obviously I was thinking about an algorithm to create harder "Jumping Julia" puzzles. Definitely doable, but for now I'll leave it at that!

Knowing that a typical maze will have branching paths at the beginning, but necessarily one good path at the end, I find it easier to start from the goal and work my way backward.

It seems to make a server request when Generating a new maze. Making the maze working fully Client side should be doable..

Just for amusement, tried:

and ended up with a 3 wide 7 high table... but with a projected Goal square at 7 wide 3 high?

This is great. Simple to get, not too simple to solve. One I will share with my kids, plus now introduced to Julia Robinson festival. Thanks for sharing.

Are these always solvable? The handful of 4x4's I've had don't seem to be.

Seems like I'm too late and it got hugged to death? Page is not loading for me.

Better challenge: generate these puzzles in a way to have a unique solution.
