Super Mario Run is a side-scrolling auto-running platformer game developed by Nintendo for mobile devices. The game features Mario, the iconic character from Nintendo, and follows him as he runs, jumps, and dodges obstacles to reach the end of each level.

The game offers three different modes: World Tour, Toad Rally, and Kingdom Builder. In World Tour, players run through six worlds, each with four levels, in a quest to rescue Princess Peach from Bowser. In Toad Rally, players compete against other players to collect coins and impress Toads with stylish moves. In Kingdom Builder, players use the coins and Toads collected in the other modes to build and customize their own Mushroom Kingdom.

Super Mario Run also introduces new gameplay mechanics, such as the ability to perform mid-air spins and wall jumps. Players can unlock new playable characters, including Luigi, Yoshi, and Toad, as they progress through the game.

Overall, Super Mario Run is a fun and engaging game that brings the classic Mario gameplay to mobile devices in a simple yet entertaining way.
