To Set (Japanese: セット Setto) is to place a card face-down on the field.
Monster Cards are Set in the Monster Card Zones, and must be Set in Defense Position. This is called a Normal Set.
With the exception of Field Spell Cards, which are Set in the Field Card Zone, Spell and Trap Cards are Set in the Spell & Trap Card Zones. In all cases, the cards are Set vertically.
