How to estimate it
Fermi’s official “Napkin math”
Mario turned up in Donkey Kong back in 1981, so he has been going about 45 years. How many Mario games come out in a year? Between the platformers, Kart, Party and the sports spinoffs, call it 6.
- Years since 1981
- 45
- Mario games per year
- ≈ 6
- 45 × 6
- ≈ 270 games
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Distinct titles featuring Mario as of April 30, 2025
- 255
- Counting each release and platform version
- 429
- ≈
- 255 games
