Yu-Gi-Oh Duel Links is rolling out its celebration for the mobile card game's sixth anniversary featuring free gems, UR and SR tickets, and an iconic card from the anime. While Master Duel has taken the lion's share of the trading card game's digital popularity throughout the past year, the franchise's initial mobile game has seen plenty of new features. September saw the addition of Yu-Gi-Oh VRAINS to the game, adding in Link Summoning and fan-favorite archetypes like Trickstar and Salamangreat. Now, the game is kicking off its sixth anniversary festivities.
