How to play Mirror Maze

A garden maze is full of mirrors โ€” and of creatures: a fish, a bird or a frog in every square without a mirror. The totals of each kind are shown under the maze.

Each number around the edge counts the creatures you see when you look in from there. Your line of sight runs straight until it meets a mirror, then bounces off at a right angle, and so on until it leaves the maze. A creature passed twice is counted twice.

The twist: birds fly off when they glimpse their reflection, so they are only seen before the first mirror; fish hide under the glassy surface and only show up in a mirror, so only after it; frogs are seen either way.

How to play Mirror Maze

Place a fish, bird or frog in every empty square so each number counts the creatures seen along its line of sight, bouncing off mirrors.

The rules

  1. Every square without a mirror holds exactly one creature: a fish, a bird or a frog. The totals of each are given.
  2. A number outside the grid counts the creatures seen looking in from there. The line of sight bounces off each diagonal mirror at a right angle.
  3. Birds are seen only directly โ€” before the line of sight has hit a mirror.
  4. Fish are seen only in a mirror โ€” after the line of sight has hit a mirror.
  5. Frogs are always seen. A creature passed twice is counted twice.

Questions

What counts as a mirror bounce?

Each diagonal mirror turns the line of sight through a right angle โ€” / and \ turn it different ways.

Can a line of sight pass the same square twice?

Yes, after bouncing round โ€” and the creature there is counted each time.

Is there always one answer?

Yes โ€” every puzzle here is checked to have exactly one solution.
