The Science of Pokemon Catching! | A Programming Mathsterpiece 🤓 Gnoggin
Big thanks to today's sponsor! You can get 20% off at Brilliant:

What is Catch Rate in Pokemon? What about the Modified Catch Rate? The capture method? Ball-chance? Why is there so much math in my Pokemon?
This video hopes to explain the evolution of Pokemon catching, how the programming of the formula has changed over several generations. Get ready for numbers! Hopefully they're correct!

Gnoggin, hosted by its creator Lockstin, is a show delving into the mysteries of Pokemon! (and other games sometimes too). Explaining everything there is to explain! Why is each Pokemon given the type it has? What are their origins? What is the lore of the Pokemon world and the design inspirations? And what does it all have to do with alchemy? Let's Go find out!

    Unless we're talking about a Quasire from Pokemon Silver. Then N = 1... never could catch a Quasire in that game... ... Thankfully, I *could* catch a Wooper. So I just evolved one of those to complete my Pokedex instead of wasting another 100 Pokeballs of every type that was purchasable in that game.

    In gen 7 a Pokémon could actually have a negative or zero catch rate(I’m not sure which one) because I’m pretty sure they removed the “no zero or below catch rate” thing for at least the heavy ball and since the heavy ball can give the catch rate a -20 it could end up being zero or below

    Didn't they also add in starting in gen VI (or was it gen V?) where any Pokemon encountered on the very first route also bypasses the catch calculations and is a guaranteed catch? I don't know if they kept that for gen VIII, but it was definitely in gens VI and VII, not sure about V

  • Deathnotefan97

    "I don't think I've ever seen [the ball miss]" I have, but only against the Legendary Birds Especially Zapdos, didn't matter how low it's HP or what ball I used, the ball completely missed Zapdos like 8 times in a row, and It happened a couple of time against Articuno as well I think I just used the f***ing master ball on Moltres, to save me the pain

    I always thougt the lvl of our pokemon had an impact because I had the feeling that catching pokemons who were low level when your pokemon was lvl 69 was easier since you can't attack or you would 1hit him

  • antialiasis

    This video has nice production values but unfortunately it's incredibly inaccurate. There is literally some kind of error or inaccuracy at least once a minute, in either a minor but still significant way (going on about how Gen V starts using "12-bit integers" and therefore catch rates can go up to 4096, which is presumably a garbling of the fact that the intermediary calculations in Gen V onwards use fixed-point arithmetic with precision to the nearest 1/4096th - but has nothing to do with catch rate values, nor with "12-bit integers"; rearranging the HP factor formula for R/B/Y, which makes it inaccurate because of rounding) or a very major way (the video maintains that R/B/Y only calculate an HP factor if there is no status condition). Sometimes it makes a big point of something that's actually completely incorrect or even the literal opposite of what is true (as with insisting that it's *harder* to catch Pokémon in thick grass the more you've already caught, when actually it's *easier*)! Anyone actually interested in the mechanics should look elsewhere.

    Ummm... Aktually... They're called "role playing games" because you play a role. It's not "roll playing games" because of the die rolling. It's a clever joke, but factually inaccurate.

    Wait so is the reason N's name is N because that's used as a Number to determine catching Pokémon and N's gimmick is that he *catches* and releases Pokémon in the area he's in for Battles. If so, that's amazing, if not, man that is a weird coincidence.

    Isn't the ball shake equation in gen 2 not M for Mumber (randomly generated) but A for answer to the previous equation? Also the dark grass chart in gen V indicates that the more pokemon you've captured the EASIER it is to capture a pokemon, not harder. Its just that to make it comparable to normal grass you need to have caught 600 or more.

  • metrux321

    Uhh... Liked the video, but... It's not rollplaying, it's ROLEplaying games xD It's about playing roles, not rolling die, hence why not all use dices.

    I came up with a theory. Are grimer and muk sandygast and palossand. Like they have the same body shape and can learn sludge bomb . Also it makes sense because muk could of evaporated into the sand and became palossand . Maybe dead muks were dropped into the isle of armour and they evaporated into the sand and became palossands and then they started breeding

    I'm thinking the shake mechanic where the ball "doesn't even hit the pokemon" is there for when you attempt to catch an npc owned pokemon and the trainer blocks the ball.

    • antialiasis

      Nah, you'll always see it if you throw a Poké Ball at a full-health legendary, for instance - if the game approximates your chance of catching it as being less than 10% (that's what that shake calculation is actually doing in R/B/Y), it shows the Pokémon not going into the ball at all and says "The ball missed the Pokémon!" This was a bit confusing and made it seem like catching it was impossible, so in the later games they made it so on "zero shakes" it does go into the ball but it bursts open immediately with the message "Oh no! The Pokémon broke free!"

    When I was younger, I heard from a friend that the stronger the pokemon (the better the stats and the nature), the harder it is to catch a pokemon. I guessed that's a myth.

    • Victory Star
      Victory Star

      @Velvet Butterfly No. He meant the same species as well. I was catching two budew (I can't remember why) in pokemon diamond on that day, and I had trouble catching the second one. Then, suddenly, my friend appeared out of no where (I was playing after school waiting to be picked up) and explained that to me. I, being a child who didn't know how to look at stats, undoubtedly listened to him and spent sometimes catching that budew. It took me about 5 pokeballs, I think.

    • Velvet Butterfly
      Velvet Butterfly

      That is roughly true. Evolved Pokemon and Legendaries have lower catch rates than common and unevolved, meaning they are harder, but that catch rate matters so little compared to everything used

    That lvl 1 regigigas from platinum while asleep and on 1 hp took me 100 ultraballs to catch. longest hour to catch a mon ever. whats worse it was pretty bad and i have to restart it and try again anyway. It also feels like crit caps have a much lower chance in sword and shield. Before the new games i didnt even think a crit cap could fail because i hadnt beforehand.
