Mirror Mazes

27th July 2015

This month I've added a new type of maze to Mazelog called Mirror Mazes.

In these mazes you have to find the shortest path from the light source at the start to the detector at the finish. The maze contains diagonal half-silvered mirrors that can either let the beam travel straight through, or reflect it through a right angle.

Here's a simple example. Start at the light source in the top left corner and find a route to the detector in the bottom right corner:

From the starting square you can move down to the first mirror in the leftmost column. This mirror either reflects the beam to the left out of the maze, or lets it pass straight through. Alternatively from the starting square you can move right to the first mirror in the top row, which either reflects the beam straight down, or lets it pass straight through.

Here's the full seven-step solution:

As an introduction to mirror mazes try Beamy. I hope to add further mirror mazes over the next few months.
