A zone (Japanese: ゾーン Zōn) is any tile for a card(s) on a playmat. 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 Card 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 top zone of the rightmost column is the Graveyard Zone, where the player's Graveyard is placed. The bottom zone is the Deck Zone, where the player's Main 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. These zones were introduced in Starter Deck 2014.
The upper row of five central zones are Monster Card Zones, where Monster Cards are played; the lower row of five central zones are Spell & Trap Card Zones, where Spell and Trap Cards are played.
The Banished Zone (formerly known as the Removed from Play Zone), where banished cards are placed, is not actually a zone so does not appear on the playmat.
Each vertical line of four zones stretching from one player's Spell & Trap Card Zone to their opponent's constitutes a column; there are five columns on the field.
