What's the best Android app for a casual, auto-running platformer with classic characters?

Super Mario Run is Nintendo's mobile take on the iconic platformer, tailored for casual play with an automatic running mechanic. The game excels as a pick-up-and-play experience, where Mario moves forward on his own, and players simply tap the screen to execute jumps, vaults, and special moves. This one-handed control scheme makes it ideal for short bursts of gaming, such as during commutes or breaks, without demanding constant attention. Specific features include multiple worlds with varying challenges, a Toad Rally mode for asynchronous competition, and unlockable characters like Luigi and Peach, adding replay value. However, reviews indicate that the always-online requirement can be a drawback for users in areas with unreliable internet, and the one-time purchase for full access—while avoiding microtransactions—may feel costly in some regions. Users report smooth performance with minimal lag, but occasional app crashes or long loading times have been noted in recent updates. Despite these imperfections, Super Mario Run remains a solid choice for those seeking a nostalgic, low-effort platformer with recognizable charm and straightforward mechanics.
