The first tournament held in the EN server was the Catfood Bowl Tournament – Season 0 in 2019.

In 2025, two were held; Battle of the Four Winds, a collaboration with a Fate/stay night movie, and JongTama Open Championship, a collaboration with the Gintama series. In 2026, the collaboration tournaments were Aincrad MahjongSoul Online, a collaboration with the Sword Art Online series, and the Zawa Zawa Cup, a collaboration with the Akagi series.
