The Musical Minotaur Maze

Here is a puzzle for your next dungeon. I have used it before. It is fun.

There is a maze in the dungeon. It has many twists and turns, to say nothing about the zombies. Those who enter the maze become lost. If they are very lucky, they end up back at the entrance. 

Only the minotaur at the center of the maze can guide you to him. 

(The minotaur can be anything, reflavor to suit your dungeon. It can be a ghost, a pirate smuggler, or even the dungeon's echoes.)

To navigate through the maze, the players must ring a bell. The minotaur at the center will ring a bell in response to help guide them. The players can discover this information by talking to other dungeon denizens or through rumors in the City.

Optional hook: You must find a specific bell elsewhere in the dungeon, not just any bell. The ringing of the bell compels you, child! 

How to run the puzzle

When the players enter the maze, they come to a series of branching paths going left or right. If they ring their bell at this fork, they hear a returning chime: high C (an octave above middle C) for right and low C (an octave below middle C) for left. 

If the players make the right choice, they progress to another fork in the maze. If they get it wrong, they get into a fight with a zombie wandering the maze and come back to the entrance.

At first, the meaning of the tones won't be understood and the direction they choose will be random. Once they get it wrong a few times, they'll understand that sometimes they hear a high tone and a low tone, and sometimes they return to the entrance and sometimes they progress in the maze. This will let players work out the meaning of the tones.

Once they've understood the pattern, you can go through a few forking paths - right, left, left, right, right - to let the players feel they've mastered it.

Then, throw in a curve ball. The next branching path they come to can be left, right, or straight ahead. If the correct path is "straight ahead," the minotaur will ring a bell that's middle C. (Distinguishing this middle tone can be more challenging than hearing "high" vs "low.") 

Again, players can use trial and error to figure out the pattern. Once they have the complete pattern, you can handwave the dozens of series of twists and turns. They arrive at the center of the maze and meet the minotaur face to face.
