The coolest thing about Pokemon GO is it allows players to catch creatures in real-time. Hence it's called an augmented reality game. It also smartly utilizes a system that somehow sorts the place where a specie should spawn. For instance, a water Pokemon may be caught in bodies of waters like lakes or canal. Apparently though, with third-party tracking tools being out of the picture, this area here is quite a challenge.
According to Eurogamer, the key is to find and/or know the increased spawn locations in Pokemon GO. It helps players understand where a certain type of creature tends to appear. While this doesn't guarantee a catch 100 percent, it somehow levitates the gameplay. So, at the end, the experience is all worth it.
All normal species in Pokemon GO tend to appear in public places. These can be schools, roads (of all kinds), business establishments, stadiums, universities and fields, among others. The list could go on and on. Under this category, it includes the likes of Clefable, Clefairy, Jigglypuff, Pidgey, Pidgeotto and Rattata. Spearow, Fearow and Wifflytuff are also part of it. Some Pokemon in this category are usually deemed regional, such as Tauros and Kangaskhan. Regardless, the chances of catching them are within the confines of the aforementioned locations.
As for those who are looking to catch rock-type Pokemon GO species, the locations are in parking areas, quarries, large commercial installations or constructions sites and highways. The creatures involved are Golem, Onyx, Kabuto, Kabutops Omanyte, Rhydon and Graveler, among others.
For steel type Pokemon, fans of Pokemon GO can simply go straight to railway stations, modern buildings and factories. Here, Magnemite and Magneton are the best ones to catch. For grass types (e.g. Bellsprout, Bulbasaur, Parasect, Exegcutte, etc.), any areas covered with grass like playgrounds, forests and farmlands. As for the ground types, the likes of Sandslash, Marawak, Cubone and Geodude can be found in locations such as ditches, streams, airports and parking areas that are concreted.
