Teachers recently received a rude awakening when they discovered every student playing Mario Kart Tour on their phones.

The app released September 25 free on the App Store and Google Play Store, and currently enjoys a 5 star rating from users.

First impressions among students were overwhelmingly positive.

"When I first played it I thought it was pretty fun," said junior Sydney Cavett.

The app generally sticks to the well-known Mario Kart formula of several Mario characters go-kart racing around a track while participating in brutal vehicular combat, all in an effort to win the race—a fan-favorite formula since its debut on the Super Nintendo system in 1992.

There are, however, a few key deviations from the formula in order to better suit the smartphone-based game. Steering the kart is now controlled by swiping left and right as well as racers and karts no longer having unique stats, like speed.

However, that swipe steering has been among the top complaints about the game.

"The steering is pretty bad, but it’s still fun," said senior Sam Elliot.

There are currently eight courses available to race, though only one is original to the app with the rest being pulled from past versions of the game.

As students continue to play the game, opinions among some have soured.

"I hate that the Gold Pass exists," complained sophomore Nate Grundberg.

The Gold Pass is a $5.99 per month subscription that allows players the get better in-game rewards after races.

Junior Ryan Appel is quite pleased with how much better playing on a phone has made her.

"I’ve never been this good at Mario Kart before, so I’m either really good . . . or the game is really easy," Appel observed.
