Link Summon

A Link Summon is the act of Special Summoning a Link Monster from the Extra Deck.

How to Link Summon
During their Main Phase 1 or 2, the turn player can Link Summon a Link Monster from the Extra Deck by first declaring the action and then selecting the Link Monster in their Extra Deck that they intend to Link Summon. Following this, they send the requisite face-up Link Materials they control to the Graveyard, as listed on the Link Monster itself, provided that two conditions are fulfilled. After that, the Link Monster is taken from the Extra Deck and placed on either an unoccupied Extra Monster Zone or Link Point in face-up Attack Position.
 * 1) The number of sent Link Materials satisfies the number of required Link Materials listed on the Link Material requirements of the Link Monster.
 * 2) The combined number of all sent Link Materials exactly matches the Link Number of the Link Monster. If a Link Monster is sent as a Link Material, it can be optionally treated as a number of sent Link Materials equal to or less than its Link Number.

In the anime
In the anime, using monsters to perform a Link Summon is known as Setting the Link Markers.

When a Link Summon is performed, the Duelist shoots forward a burst of energy which creates an Arrowhead portal in the sky, which the Duelist and their monsters fly through. The Link Materials then transform into red and white streaks of energy that enter the appropriate Link Markers, causing them to turn red. The Link Markers are then said to have it's circuit combined. The portal then glows white, and blue energy converges to form the monster and the Link Markers around it. The monster and the Duelist then emerge from the Arrowhead portal.

Unlike previous summoning methods in the anime, the Duelist states the summoning conditions of the Link Monster before calling out the monsters he/she is using to summon it.
