In a series of posts I will show you how to make a maze in a wide variety of design constructions. The 39th example with look at the Unsolvable Maze construction. It is one of the most enjoyable maze constructions to make. Let’s define what I mean by Unsolvable Maze, then get into the example. Every example will use the sample basic outline (the state of Ohio) to better illustrate the differences between each maze type.

Unsolvable Maze - A maze that doesn’t have a solution.

(ALTERNATIVE definition) A maze so difficult that the solver gives up rather than continue solving it.

HOW TO MAKE AN UNSOLVABLE MAZE - OPTION 1 (NO SOLUTION)

• Step 1 - Choose Your Maze Construction

This step by step will be much different that previous “How to Makes”. An unsolvable maze can come in ANY maze construction. So determine which construction you prefer.

• Step 2 - Follow the Step by Step Instructions

• Step 3 - Close off any Solutions

And there it is. When you make the maze do not leave any solution possible. This is mean. But maybe that is why you are here. To make this even more difficult close up a point in the middle of the maze (not at the end). If you close all possible solutions pathways near the exit, a backward solver will easily figure this out. I assume a designer of this would want to be at their most terrible.

Below is an additional example. You are a terrible person. Unless this is for April Fool’s Day.

Below I will discuss how to make an Arrow Maze that is very difficult. But there is also the option to create an Arrow Maze with dead ends (unlike other maze types, an Arrow Maze does not have any). In this first example there is NO solution and if you try to solve it you will find yourself in an everlasting loop ! Try it yourself.

HOW TO MAKE AN UNSOLVABLE MAZE - OPTION 2 (VERY DIFFICULT)

This second option is a variation on the above instructions with a variation only in step #3.

• Step 1 (same as above) - Choose Your Maze Construction

This step by step will be much different that previous “How to Makes”. An unsolvable maze can come in ANY maze construction. So determine which construction you prefer.

• Step 2 (same as above) - Follow the Step by Step Instructions

• Step 3 - Make it REALLLLLLLLLLLLLY difficult to solve

Make a maze that is extremely difficult to solve using the following 8 things in your toolbox:

8 Designs Decisions That Make a Maze Difficult to Solve:

• Make a very large. The larger the maze the more difficult it can become. The more dead ends. The more pathways to keep track of. Just more.

• Make a very high number of intersections. The more choices the solver has to make, the more often they will make a wrong turn. Simple math.

• Make the dead end pathways very long. When you create a dead end, don’t make it obvious just after the choice is made. Make the dead end take a long time to be discovered.

• Make many branches off of the dead ends pathways. So you take a long dead end pathway but do not discover it for a long time so you backtrack to your last intersection and take the other branch and it is a dead end also. So you backtrack again to the previous intersection and take the other direction and it is a dead end also ! etc.

• Include a few looping dead ends. What do I mean by this ? Well, have an intersection that breaks off into two directions (again, preferably these are long pathways), which both lead back to the exact same spot in the maze. The more looping pathways, the more difficult the maze to solve. It may make the maze less frustrating depending on the temperament of the solver. Would you rather hit a dead end, or not hit a dead end and return to where you started ?

• Consider using weaving pathways. These paths go under and over one another and make seeing dead ends “early” much more difficult. Weaving Mazes and Pipes Mazes both use this construction method.

• If you are making a specialty maze, give the solver an exponential number of possible moves they can make (see the Slide Arrow Maze example below). An intersection with 4 choices is more difficult to keep track of than an intersection with only 2.

• Design the maze in TWO directions. This prevents a person from backtracking to solve a maze from the goal to the start.

I do NOT suggest using this method to make a maze unsolvable:

• Make the pathways very small or in poor colors (both are difficult to see), with the need to zoom into them in order to navigate well. Don’t make a maze designed to be difficult to follow/see, make a design that is difficult to SOLVE.

EXAMPLES OF VERY DIFFICULT MAZES

The first example is a Slide Arrow Maze. In this type of maze you start at the red arrow and you may move to any block that it is pointing to (but no jumping gaps). So your first move can be to either of the two blocks below it. If you pick the first block below you have 3 subsequent choices. If you pick the second possible arrow you will then have 8 possible next moves. Why this maze is so difficult is that there is only one correct solution, so with so many choices each move you are bound to make many mistakes and get stuck ! Try it. I WANT the solver to get frustrated.

And this second example I did for a project. This is a regular Arrow Maze, but it is also the largest Arrow Maze in the world (probably). This is difficult because of it’s sheer size. I gave a few checkpoints along the way (the blocks with the black background). It also includes hundreds of loops. I think it is a fun maze, but I think many people will get frustrated and stop. If you do try to solve this maze, time yourself and send me a note on how long it took you !

Here are the solving rules if you have never done an Arrow Maze:

Good Luck designing an unsolvable maze !
