Reverse Arrow Mazes

1st October 2015

This month the competition introduces a new type of logic maze I've called Reverse Arrow Mazes.

The following simple example illustrates the idea. Start in the top left corner and find the shortest route to the target in the bottom right corner:


From the starting position you follow the arrow, just like in a normal arrow maze; so, from the arrow on the starting square you can go to any of the three squares below it.

However, now you flip to following the tail of the arrow. For example, from the square just below the starting square you can go to any of the three squares to its right.

Continue in this way, alternately following the arrow heads and tails, until you reach the goal.

Here's the solution:


At first sight this may seem like a minor modification of the standard arrow maze, but in fact this additional rule turns the maze into a state maze. In other words, your choices from a given square depend on how you got there. As a result, your route may have to visit some squares twice (as in the above example). This makes Reverse Arrow Mazes more challenging and more fun than the standard arrow mazes.

Got the idea? Now try your hand at the Reversibubble maze.
