Nintendo’s long-awaited ‘Mario Kart Tour’ will be released on September 25.

The upcoming spin-off smartphone app was set to be released before the end of the financial year on March 31, but the company revealed gamers shouldn’t expect it until the summer.

Now they’ve released a trailer and revealed it will be available on iOS and Android next month, with pre-registration open now.

Explaining the delay, Nintendo previously stated:

“The smartphone application ‘Mario Kart Tour’ will be scheduled to be distributed in the summer of 2019 in order to improve the quality of the application and expand the content of the service after delivery.”

The title was announced back in February 2018, with the video game giant hinting that work was almost complete.

It wrote at the time:

“The checkered flag has been raised and the finish line is near. A new mobile application is now in development: Mario Kart Tour! #MarioKartTour Releasing in the fiscal year ending in March 2019.”

The most recent instalment of the franchise, ‘Mario Kart 8’ – which was released for the Wii U before a Deluxe version followed for the Nintendo Switch – sees players take part in Grand Prix races against 11 CPU players to win trophies.

‘Mario Kart 8’ also features an online mode and a localised multiplayer to battle it out in races against friends, which is a feature that will likely be implemented onto the mobile game.

The news of the upcoming smartphone version suggested an end to Nintendo’s past reluctance to expand into mobile gaming, as they previously chose to focus on their own dedicated gaming devices.

‘Miitopia’, ‘Super Mario Run’, ‘Fire Emblem Heroes’ and ‘Animal Crossing: Pocket Camp’ have all been released for mobile devices, as well as the massively popular augmented reality game ‘Pokemon Go’, which was released through Niantic and The Pokemon Company.
