The title recorded the second highest launch month downloads of any mobile game in history, according to data from Sensor Tower.
In comparison, record holder Pokémon Go achieved 163 million downloads in its first 30 days, despite receiving a staggered worldwide rollout.
Mario Kart Tour is by far Nintendo’s most successful mobile title in terms of first month installs, registering over 5.5 times as many downloads as Super Mario Run did during its launch month.
The free-to-start racing game is Nintendo’s second highest earning mobile title in terms of first month player spending, grossing $37.4 million compared to the $67.6 million generated by Fire Emblem Heroes during its launch month.
Mario Kart Tour microtransaction mechanics include a gacha-like system for unlocking content, as well as a Gold Pass $4.99/£4.99 monthly subscription service that lets players unlock more in-game rewards. The Gold Pass is available for a two-week free trial period before users are charged.
Nintendo is expected to introduce online Mario Kart Tour multiplayer in a future update.
