Rules
A Labyrinth Duel is considered part of the Duelist Kingdom rules, so all the basic from that tournament still apply.

When "Labyrinth Wall" is Summoned, the Playing Field becomes a 9x9 grid with walls along the lines of some squares forming a maze.

Monsters can move a number a number of squares equal to their Level. Monsters can attack monsters within 1 square of each other. Flying monsters may not pass through the maze.

"Shadow Ghoul" may be fused with the "Labyrinth Wall" to Summon "Wall Shadow". The field still remains and "Labyrinth Wall" is not destroyed when "Wall Shadow" is Sumoned or destroyed. "Wall Shadow" may attack monsters anywhere on the grid adjacent to a wall.

"Magical Labyrinth" randomly rearranges the walls.

"Dungeon Worm" can tunnel under the grid.
