The Mario Kart Tour beta test has just got underway in Japan, and it really didn't take long for all sorts of details and screenshots to find their way online.

If you don't want to be spoiled ahead of the game's release, this is your final chance to head back to our home page and away from all the leaked images. We'll kick things off with details shared online by those who have had some time with the game.

Mario Kart Tour Game Details

A whole bunch of Mario favourite characters appear to be playable, including Mario, Luigi, Peach, Daisy, Toad, Toadette, Rosalina, Waluigi, Baby Peach, Baby Daisy, Baby Rosalina, Metal Mario, Larry, Lemmy, Ludwig, Dry Bones, and Dry Bowser. The game is played vertically, appears to have a selection of retro tracks, and there are two laps per race.

Interestingly, you appear to control your kart with a swipe on screen and you'll unlock more characters as you play. Your kart automatically accelerates, leaving you to swipe left and right to steer.

Mario Kart Tour Images

Lots of images have begun to appear online from users taking part in the beta test. We've shared some of them for you to see below:

Of course, with these images coming from the beta test version, we can probably expect to see the odd change here and there in the final product. Still, this should give you a good indication of what it'll be like when it launches this summer.
