Solving mazes

- Mazes on paper are an interesting problem, but frustrating as you try to find your way through. Rob shows a simple way of revealing the path through a maze - as long as you are allowed to draw on it.

It is faster if you only draw a line closing off the dead end entrance.
Brilliant! I have been creating mazes for over 30 years and this never occurred to me. However it does make sense and seems rather obvious once you see it done. Thanks for sharing!
No problem. My pleasure, Rob
Uhm.. achshually the fastest way to reach the end is to start going towards the end if you don't find any close ends. You'll swipe your mouse way slower than you can actually solve the maze so going in wrong direction doesn't cost almost any time because you know it before you start going there 🤓☝
I know I am super late, but you can notice that in the bottom right corner of the first uncolored maze there is a missing wall segment that the second colored maze has added in. In the first maze, you can solve it much faster by taking that exposed route.
Glad you pointed that out . I think he may have drawn in that line on the second Maze . I have seen Mazes that had more than one solution .
Yeah
That's a neat way of taming the monster :-) Brilliant! Thanks for sharing.
UjjwalRane No probs, Rob
this helped me solve a maze that I tried to solve for 9 years. Thanks my guy
If it took that long, and it still kept your interest, that must've been one awesome maze! 🙂 Do you have a hyperlink to it, or was it in a book or magazine? I'd like to give it a try. Thank you in advance.
How big was it, and what were the structure of the walls?
A-maze-ing. Why didnt i think of that?
Just go around the maze
Awesome thanks!! Will this work for multiple entrance/exit points?
There’s also the right hand rule, where you will eventually solve any maze if you keep your right hand on the wall to your right as you walk through from entrance to exit. You will probably have to double back through some dead ends though.
Totally agree, Patrick! It may be a longer pathway, but, yes, it is a sure-fire method to solving any maze. It really does work, and I think it works on the left, too! 😃👍
Specifically, you will find an exit! If the solution is in the center somewhere then you can be looped around it. Not perfect.
Only if the maze is a square or a rectangle if its any other shape it wont work
cool
Is that cheating?
it's only cheating if there's a rule saying you can't do it
depending on where you are or who you play with, rules can simply be different
you can ask if you're allowed to do something before doing it, if you're really unsure
but you shouldn't be punishable for doing something nobody said you couldn't, but i may get a warning
Easy
This rule is incomplete. This is easy to see if you make long dead end and split the end in two or more dead end paths. You will only mark those short dead ends, but not the long path. You can improve this rule though. When you color a dead end and come to a crossing and there is only one direction to where you can continue (because other directions are already colored), you keep coloring. But even this rule fails if you replace the dead end with a loop or add a loop on the stem of the dead end path.
So, this sneaky way is not sneaky enough to be foolproof.
I was thinking the same, and you're improved rule should indeed do the trick. Re the loops, in a puzzle book I would expect there to be only mazes with one unique solution, so there won't be any loops.
@@fondueeundof3351 (On the video there was a loop along the solve path, BTW.) If the loops are only on those dead end paths, the solve path should not visit them because your path would have to return back from visiting the dead end loop. So adding the loops along the dead end paths won't effect the uniqueness of the solution.
