Protip: each of the things has a (occasionally humorous) description, so don't just blow past everything because you're excited to find a use for the 500 Pokémon you had memorized by heart ten years ago (no personal experience involved here at all /s).
Actually made this a little while ago for Dutch municipality names. Works quite well as even Dutch people get confused about which ones are real. https://diasli.de/848
Exactly what I was missing after 15~20 questions (and then I left)
Seemed easy at first (got the first 5 right), but I guess that was mostly luck because I got a lot of the next ones wrong.
Edit: being from France, pokemon here have different names, making the english names less recognizable (I never played the games anyway so that doesn't change much for me)
French here too but playing Pokemon Go in English. After a while I can recognize most names but I still think the French names are funnier. The translation team did a real good job. Also, a lot a English names are straight coming from Japanese (e.g. Zubat) which make use of some English in the first place, so there is a bit less creativity on this side.
I was thinking about naming some of my npm libraries after pokemons! But then found all of the good ones were already taken, so I switched to Spanish/Japanese words (I'm a Spaniard living in Tokyo)
