Answer & explanation
Official answer
200,000,000
Game Boys
How to estimate it
Fermi’s official “Napkin math”
There were really two generations: the original Game Boy with its Color update, and the Game Boy Advance. Each was the handheld of its decade, the one in every kid's backpack. How many of each? Call it 100 million.
- Game Boy generations
- 2
- Sold per generation
- × 100,000,000
- 2 × 100M
- ≈ 200,000,000
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Game Boy, Pocket and Color (Nintendo)
- 118.69M
- Game Boy Advance, SP and micro (Nintendo)
- + 81.51M
- Total
- ≈ 200,200,000
Reference cited by Fermi: Nintendo IR dedicated hardware sales: Game Boy 118.69M plus Game Boy Advance 81.51M
