1. Question

Can a player perform an Extra Link (U-Link) when their opponent has already linked both Extra Monster Zones through their own Link Monsters?

The example discussed on Reddit involves a player controlling Decode Talker in the left Extra Monster Zone, while the opponent controls three Firewall Dragons in the second, third, and fourth Main Monster Zones. The question is whether the player’s Link Monster can continue the Link path and reach the other Extra Monster Zone.

2. Reddit Discussion

The Reddit discussion received a clear answer from a Judge & Moderator and an additional response from a user identified with the YGOrganization badge.

The Judge & Moderator confirmed that yes, the player can perform the Extra Link and provided a link to Konami’s published Extra Link rules as supporting material.

Another commenter gave the relevant condition: the player’s Link Monster must be co-linked with the opponent’s Firewall Dragon. In that situation, the Link connection can be used to continue the Extra Link across the opponent’s linked monsters.

The discussion therefore focuses on the fact that an Extra Link does not require all of the Link Monsters involved to belong to the same player. The important factor is whether the Link Monsters form the required co-linked sequence.

3. Summary of the Reddit Answer

Interpretation	Result
You can Extra Link through an opponent’s Link Monsters	Yes. The Reddit Judge & Moderator confirmed that this is possible.
The opponent has linked both Extra Monster Zones	This does not by itself prevent the Extra Link.
Your Link Monster must be co-linked with the opponent’s Link Monster	Yes. The additional response specifically identifies co-linking with the opponent’s Firewall Dragon as the relevant connection.
The Link Monsters forming the Extra Link must all be controlled by the same player	No. The discussion indicates that the Link path can involve the opponent’s Link Monsters.

The key point is that control of the Link Monsters does not by itself determine whether an Extra Link can be completed. The relevant requirement is the Link relationship between the monsters, including whether they are properly co-linked.

The Judge & Moderator also directed readers to Konami’s published Extra Link rules as the supporting authority.

4. Conclusion

Yes. A player can perform an Extra Link even when their opponent has already linked both Extra Monster Zones.

In the example discussed, Decode Talker can form the necessary Link connection with the opponent’s Firewall Dragon, allowing the Link sequence to continue through the opponent’s co-linked monsters.

The important requirement is the co-link relationship, rather than all of the Link Monsters being under the same player’s control.
