The original 151. This quiz covers every Pokémon from Red, Blue, and Yellow — #0001 Bulbasaur through #0151 Mew, the Kanto roster that started everything in 1996.
It's the most famous cast in video game history, which makes it the fairest test on the site: everyone remembers Pikachu, Charizard, and Snorlax. The real question is whether you can dig up the Safari Zone filler, the fossil duo, and that one fish everyone forgets between Seaking and Staryu.
How to play
Type a name and the matching sprite flips over immediately — you can keep typing without touching the mouse.
Punctuation never blocks you: "farfetchd" and "mr mime" are accepted, apostrophes and periods optional.
Nidoran♀ and Nidoran♂ are separate answers — type "Nidoran F" and "Nidoran M" (or the plain names with gender words) to get both.
The clock starts counting up at your first keystroke; hit Give Up any time to end the run and see what you missed.
Feeling confident? Who's That Pokémon? mode hides every sprite so you're naming all 151 from pure memory.
What counts in this quiz
All 151 Kanto species, Pokédex #0001–#0151, exactly as they appeared in Red and Blue.
The legendary birds and both psychic cats count — Mew closes the list at #0151.
The two Nidoran count as two separate answers because they hold two Pokédex numbers (#0029 and #0032).
What's not included — and why
Alolan and Galarian takes on Kanto Pokémon (like Alolan Vulpix or Galarian Meowth) aren't separate answers — regional variants share the original species' number.
Mega Charizard, Mega Mewtwo, and every other Mega fold into their base species — naming the species is always enough.
MissingNo. is a glitch, not a Pokémon — it has no Pokédex number and isn't on the board.
Good to know
Rhydon, not Bulbasaur, was the first Pokémon ever designed — it sits at index 001 in the original games' internal data.
Mew was quietly added to leftover debug space on the Red and Green cartridges by programmer Shigeki Morimoto, becoming the franchise's first Mythical.
Nidoran♀ and Nidoran♂ got separate Pokédex entries because Gen 1 had no gender mechanic — every other Pokémon was officially genderless until Gold and Silver.
Clefairy was nearly the anime's lead Pokémon before the role went to Pikachu — which is how Pikachu became the series mascot.
