| Please come and explain that to my young daughter. Some of

| "OSM" is just data. You can supply your own renderer.

| The orange highlight will disappear if you click the X.

| Also, if the hedges were mapped, they would appear in

| Ah, a maze where the 'left-hand rule' doesn't help.

| Oh no! Guess we need a slime mold to solve it.

| From a first glance, cycles, but is it really a maze without
| those?
| kfixjviv wrote:

| LeoPanthera wrote:
| A maze where the goal is not on the edge of the maze. In

|
| 3-dimensional mazes (which have bridges or tunnels) also
| often cannot be solved with this rule.
| zvr wrote:
| You first statement is not correct. The rule is perfectly
| useful to solve mazes where the goal is in the center.
|
| The requirement is that the walls should be connected,
| i.e. that there are no free-standing walls somewhere in
| the maze not connected to the border walls, for example.
| LeoPanthera wrote:

| Hopefully this makes sense. I'm sure there's a propper

|
| Of course in a maze with cycles you might still reach the
| goal, but it's not guaranteed. For example there's a cycle
| in Hampton Court Maze, but the left- and right-hand rules
| both get you to the goal from the entrance.
