Pokémon Go Halloween Event: Rare Shiny Sableye Pokémon Available

Software development company Niantic Labs, the parent company of Pokémon Go, is set to hold another Halloween event this year. The company’s Halloween event last year was the first in a series of holiday-themed events and propelled the game to become the top grossing app in the Google Play Store and the App Store.

This year’s event is expected to spawn the rare Shiny Pokémon Sableye, which generally has a low spawn rate of 0.3 percent, that too in the Pokémon Go Plus version. The Pokémon was found during a new survey submitted on Wednesday regarding the Pokémon Go Plus. The Plus version is a paid version of the game, which generally has a higher spawn rate than the regular game.

The chances of finding this Pokémon are better with the upcoming event. Shiny Pokémon glow on your screen and are uncommon to find.

To find the Pokémon, a user needs to crack as many 10m eggs as possible. In case the Pokémon emerges from the eggs, it is advisable to click on it as soon as possible. The Shiny Pokémon will be available both in the wild and in eggs.

Silph Road had also uploaded the link to a survey, completing which increases Sableye spawn. However, the survey is no longer available on Google Docs.

Some users even reported seeing other rare Pokémon such as Duskull spawn from eggs. A user even reported seeing two spawns in 18 eggs, which means that some users might get lucky during the event.

There is no concise data available regarding spawns but according to a user called Rathbunkum, there might be many variations in the spawning rates.

"You have to be careful here — chi-square is comparing observed distributions to expected distributions. Did you punch the numbers 13, 25, 3918, 6736 into that website? Because that wouldn't really be the right way to look at this data. If you wanted, you could use the non-plus users' data as the 'expected' distribution, and use those proportions to generate expected rates to compare the plus users' data to," he stated on the Reddit thread.

He further explained that the occurrence might be an anomaly and not the norm.

"But what if the non-plus users' data is inflated by random chance, and the actual expected occurrence is 1/256, not 1/270? That being said, doing what I described, and trying 1/252 as the expected rate still give you an outcome that's reasonably likely to happen by pure chance. You could also assume the actual rate is 1/256 (aka 28), since it seems like we're approaching that. Then you could do a simple z-score test, which would show you we're considerably less than 1 standard deviation away form the norm. So nothing super crazy at the moment."

Niantic increases the spawn rates of rare Pokémon to serve as an attraction during such in-game events, which increase player participation in the game.
