Super Mario Party has sold over 1.5 million units since launching in early October, Nintendo revealed this week.
Released worldwide on October 5, Super Mario Party reportedly had "an extremely strong start compared to other instalments in the series".
High sales of the game are also driving an increase in Joy-Con sell-through, and Nintendo says the accessibility of the game also has potential to drive hardware sales.
The latest Mario Party release is the first series' instalment on the Switch, and Nintendo says the game speaks to the "play anytime, anywhere, with anyone" concept of console.
The platform holder added that it expects Super Mario Party to become an evergreen title.
