Here's the news we've all been waiting for: Mario Kart is now available to download on iOS and Android. The release of Mario Kart Tour marks the first time a game from the series has appeared anywhere outside a Nintendo console or an arcade machine, as Nintendo continues to expand its lineup of smartphone games.

Here's all you need to know, from platform availability to key gameplay details. 

When was Mario Kart Tour released?

While Nintendo originally claimed that Mario Kart Tour would be released by March 2019 at the latest, the company confirmed that Mario Kart Tour had suffered a delay.

The closed beta tests took place through the summer, and Nintendo finally confirmed in August 2019 that the highly-anticipated game would be released on iOS and Android on 25 September 2019. That's today, and you can now download the game on the App Store and Google Play

Which platforms is Mario Kart Tour available on? 

While Super Mario Run initially launched as a timed iPhone exclusive, subsequent mobile games Animal Crossing: Pocket Camp and Fire Emblem Heroes have both been multiplatform from the start. The good news is that it's a similar story with Mario Kart Tour, offering a simultaneous launch on both iOS and Android.

How much does Mario Kart Tour cost?

While Super Mario Run experimented with giving away the first few levels for free and charging a one-time fee for the rest of the game, it's clear that as far as Nintendo is concerned the model didn't convert to as many sales as it hoped.

It's had much more success with Animal Crossing and Fire Emblem, both of which rely on micro-transactions, and Nintendo has confirmed that it'll offer more of the same here. Expect to pay extra to unlock certain characters, karts, or tracks - or at least to unlock them faster than you would through normal play.

Mario Kart Tour features and gameplay

It's a Mario Kart game, so we have some idea of what to expect: racing, Nintendo characters, and silly, colourful weapons. Hopefully, this will include all the underwater and zero-gravity elements of the 5-star Mario Kart 8: Deluxe on Switch, which is arguably the best the series has ever been.

The 'Tour' element of the name might give us some clue about the specifics of this game though - to us that suggests Nintendo will be placing the focus on online multiplayer, in line with its other smartphone titles. Expect multiplayer races, online leaderboards, and some sort of friend mechanic.

We'll be jumping into the racing action today and will update this section with more in-depth gameplay details soon.
