If you manage to beat all the Pokémon at a given gym and lower its prestige to zero, you can take over it. You’ll have to assign a Pokémon to defend the gym, and if multiple trainers in your team add Pokémon (depending on the gym level), the one with the highest CP becomes the gym leader. You may even come across an unclaimed gym while wandering around. If you do, post up one of your stronger Pokémon to defend it on behalf of your team. Be aware that putting a Pokémon in a gym means it will be unavailable until it is defeated and returned to you.

Unfortunately, maintaining control of a gym does not impart any bonuses or benefits to your Pokémon; it simply increases the prestige of the gym, and a higher prestige means more trainers can add Pokémon to defend it. So, maybe don’t leave you’re highest level Pokémon behind — they could be gone for a long time.

However, that shouldn’t stop you from trying to power up your team and take on as many gyms as possible, as every day you maintain control of a gym nets you daily bonus items, including stardust and Pokécoins. You can claim these rewards by going to the Shop. Look for the icon in the upper right. You’re eligible for rewards the moment you claim the gym, so it’s a good idea to grab them immediately, before someone else has a chance to knock you out of it.

Want to know what your Pokémon’s strengths are? As we mentioned earlier, every Pokémon in the game has “individual values” for attack, defense, and stamina that dictate how powerful it can become over time. If you are curious about how strong your Pokémon can become, you can have your Pokémon “appraised” by your faction’s gym leader, which will generate a message based on their individual values.  To appraise a Pokémon, tap the button in the bottom center of the screen…

Some final Pokémon Go tips for expert players. At this point, you’ve got all the info you need to begin you quest to catch ’em all, and excel at being a Pokémon trainer. Before long, you’ll have a cadre of high-powered Pokémon and probably a few gym captures to your name. However, there’s always more to learn, such as being able to check the server status before you head out. Here are a few more final miscellaneous tips to help you.

Walk, don’t ride: Walking and running is better than playing on the bus or train, as it will be easier for the game to accurately know your GPS position. Also, please don’t play while driving a car or riding a bike. Not only is this extremely dangerous and hazardous to others, your catching skills will suffer due to your lack of attention. If you need to catch a Pokémon while driving, bring a friend along to play in the passenger seat. Even this can be problematic though, as moving at high speeds will sometimes confuse the servers, which, in turn, can mess up the appearance of Pokémon. Moving too quickly can also cause Pokéstops to stop working properly, and can prove problematic when you’re trying to cover more distance.

Keep the app open: Yes, Pokémon Go can be a battery hog, but if you’re serious about finding Pokémon and hatching your eggs efficiently, then try to keep the app open and running for as long as possible. Of course, only do so if you can manage the distraction. Keep it off while driving or operating vehicles, stay aware of your surroundings, and don’t drain your battery just for a potential shot at a Dratini. But, if you’re in a suitable location, and can spare the battery life, then what are you waiting for?
