How Many Mario Games Exist?

There is no exact count because "Mario game" has no fixed definition and new titles—especially fan projects—appear constantly.

Why It's Impossible to Count Precisely

• Scope Ambiguity: Does it include only Nintendo-published games? Spin-offs (Mario Kart, Mario Party, sports titles)? Cameos (Super Smash Bros.)? Educational titles? Mobile games (Mario Run, Dr. Mario World)?
• Fan Games & ROM Hacks: Thousands of fan-made games exist (Mario Builder, SMBX, custom engines). ROM hacks of Super Mario World alone number in the tens of thousands (SMW Central hosts >30,000). New ones release daily.
• No Central Registry: Nintendo doesn't publish a master list; fan databases (MarioWiki, MFGG, SMW Central) track subsets but overlap and miss obscure entries.

Rough Estimates (Official Nintendo Releases Only)

• Mainline Platformers: ~20 (2D & 3D)
• Spin-off Series (Kart, Party, Sports, RPG, etc.):b> ~100+ distinct titles
• Handheld / Mobile / Arcade / Plug-and-Play: Dozens more
• Total Unique Official SKUs: 200–300+ depending on counting rules (regional variants, re-releases, bundles).
