A zone is any tile for a card(s) on a playing field. Each side features 16 zones, divided into 5 columns of 2 zones each with 2 end columns with 3 zones each.
The top zone of the leftmost column is the Field Zone, where the player's Field Spell Cards are played. The bottom zone is the Extra Deck Zone (formerly known as the "Fusion Deck Zone"), where the player's Extra Deck is placed.
The middle zones of the left and rightmost columns are the player's two Pendulum Zones, with the blue Pendulum Zone on the left and the red Pendulum Zone on the right, where the player's Pendulum Monsters are played as Spell Cards.
The so-called "Banished Zone" (formerly known as the "Removed from Play Zone"), where banished cards are placed, is not actually a Zone, so it does not appear on the playmat. However, in video games it is typically located to the right of the Graveyard Zone.
Each vertical line of four zones stretching from one player's Spell & Trap Zone to their opponent's constitutes a column; there are five columns on the field.
