Arrow Maze Design Case Study - Part 7 START / GOAL

Welcome to Part 7 of our Arrow Maze Design Case study. We will look at the Start Goal block in this case study. It is a block that is a fun way to challenge the solver to determine where exactly they are going (and from where they are starting).

Here is an overview of what we will be covering in the 14 part series:

Arrow Maze Design Case Study - Part 7 - Using the START GOAL

For this example I will use a 9x9 box Arrow Maze, and use 2 START GOAL blocks. If you are unfamiliar with this block it adds a new twist to solving the maze because the solver must determine which block is the START and which block is the GOAL. Incorrect pathways lead back to where they started from, with only one pathway leading between the 2 blocks. Try this small START GOAL Arrow Maze.

So how did you do ? Were you lucky enough to choose the right pathway initially ?

Because the S/G blocks are in the corners there are limited choices (to help you out a bit). The top left corner has 3 choices leading from the block while the bottom has 2 choices. 2 blocks are used, 1 for each corner S/G to bring pathways back to them.

From a construction standpoint this means that both incorrect pathways and the eventual correct answer will share a few steps along a pathway (usually at the end). Essentially a bunch of paths lead back to the start, while one pathway connects to one of the wrong pathways from the other side to create a solution. Hopefully this simple diagram shows what happens…with the green pathway becoming the answer.

Arrow Maze STARTGOAL explanation

One major consideration when using START GOAL blocks is that you are forced to create many pathways and they take up a lot of room in the maze. If you branch the pathways out with a lot of intersections you will create a lot of pathways to eventually close. So, using S/G blocks is best done for larger mazes.

My next example uses 2 S/G blocks very close to each other and a total of only 4 outgoing pathways from each. Should be easy, right ? Give it a try.

If you want to add complexity, consider a START GOAL block. I find them to be a lot of fun as a solver !
