Super Mario Kart, like many Nintendo games, has its share of charming details and hidden quirks:

- Luigi's Mansion Reference: In Ghost Valley tracks, if you look closely at the background, you can sometimes spot a small, pixelated mansion that resembles Luigi's Mansion, a game that wouldn't be released for many years later.
- Character-Specific Taunts: Each character has unique voice clips and animations when they get hit, fall off the track, or win a race. Pay attention to these small details for added personality.
- The 'Invisible' Wall: On some tracks, particularly those without guardrails, there are often invisible walls that prevent you from falling off in certain areas, even if it looks like you should. Learning where these are can be a subtle advantage.
- The 'Fake' Item Box: While not present in Super Mario Kart, the concept of a fake item box (which would spin out players who hit it) was introduced in later Mario Kart titles. It's interesting to note its absence in the original.
- The Grand Prix Ending: After winning the 150cc Special Cup, you'll be treated to a special ending sequence that features all the characters and a unique celebration. It's a rewarding conclusion to your karting journey.
These small details add to the charm and replayability of Super Mario Kart, reminding players of the care and creativity put into this groundbreaking title.
