The "Mutual Link" refers to a state in which 2 Link Monsters Linked to each other with their respective Link Marker. If all the monster in the Monster Zone between the two Extra Monster Zone, on either side of the field, are Mutually Linked, the player with the Link Monster in the Extra Monster Zone may have acess to "Extra Link" so that they may use both Extra Monster Zone for themselves

Example 1: From its controller's Left, "Firewall Dragon" is in the 3rd Main Monster Zone, and "Gaiasaber, the Video Knight" is in the 2nd Main Monster Zone, as "Gaiasaber" have a Link Marker that points to its Left, Bottom and Right; While "Firewall Dragon" has Link Marker pointing Up, Down, Right and Left. As "Gaiasaber" is Linked to "Fireeall Dragon" and "Fireeall Dragon" is also Linked to "Gaiasaber": Both monster are now in "Mutual Link" with each other.
