How to get a Master Ball in Pokémon Go, and when is it best to use one?

Years after the game first arrived, a Master Ball can be obtained in Pokémon Go. The Master Ball is perhaps the most iconic Pokémon-catching device of all time. First appearing way back in Pokémon Red and Blue of the main series, the Master Ball has a very special trait — a 100% catch rate on any Pokémon you use it on. Long-time players of Pokémon Go will be very familiar with that sinking feeling of finishing a raid and failing to catch the subsequent encounter, and with the Master Ball, this is one way to ensure the Pokémon will definitely be yours. However, know that Master Balls are very rare, and should be used sparingly. With that in mind — how do you get a Master Ball in Pokémon Go, and when should you use one? Table of Contents How to get a Master Ball in Pokémon Go New Master Balls are added to Pokémon Go as part of seasonal or timed research quests. The next opportunity will be with the “Masterwork Research: Master Ball” research quest, which debuts on Friday, Oct. 4, part of Season 16: Max Out. Unlike previous Master Ball research, which were free for all players, this is part of a premium research ticket which costs $8, and is available to purchase until the “Galarian Expedition” event ends on Oct. 11, 2024. Once purchased, it’ll remain in your Special Research tab, meaning there is no time limited for completing each step. This is not the first time a Master Ball has been added to the game. Previous releases include: * “Let’s Go” Special Research as part of Season 10: Rising Heroes, after completing the fifth step. This is when the Master Ball first debuted, and if you logged into the game before the season ended on June 1, 2023, the opportunity to complete the quest and earn a Master Ball will still be available in the ‘Special’ quests tab. * “Timed Investigation: Master Ball” as part of Season 12: Adventures Abound. This was time-limited research which ran until Dec 1, 2023, and involved a variety of lengthy objectives, including catching 1,000 Pokémon, spinning 300 PokéStops and completing 150 Field Research tasks. * “Masterwork Research: Catching Wonders” Special Research quest. Appearing during Season 14: World of Wonders, if you logged into the game before the season ended on June 1, 2024, the opportunity to complete the quest and earn a Master Ball will still be available in the ‘Special’ quests tab.

Unlike the main games, where the Master Ball is often a one-off item, it’s possible to acquire more than one Master Ball in Pokémon Go. To date, it has debuted in four seasons so far — Season 10, Season 12, Season 14, and Season 16 — as a mix of free Special and Timed Research. The current track record suggests a new Master Ball will be available every other season — meaning we can expect a fifth Master Ball as part of Season 18 sometime between March and June 2025. And yes, you can carry more than one Master Ball at once — so if you’re not sure what to use it on, there’s no rush in keeping a few in your inventory. Either way, Master Balls are rare — so earn them while you can! When you finally get your hands on one - what is it best used for? Master Ball best use: When should I use my Master Ball in Pokémon Go? Master Balls are very rare, and with a 100% catch rate, should ideally only be used in very specific circumstances. What you decide to use it on is entirely up to you — however, we have some recommendations for the best use of a Master Ball: * Galarian Articuno, Zapdos, or Moltres found when using Daily Adventure Incense, which currently have a 0.3% catch rate and a 90% flee rate, and are arguably the most difficult Pokémon to catch in the game. * A high IV legendary encounter following a raid that you want to level up, such as Mewtwo. We recommend using your regular set of Premier Balls first, then using a Master Ball as a last resort. * Incredibly rare wild encounters such as the “Lake Trio” Uxie, Mesprit or Azelf, or Unown — the exceptions for Unown being a letter/form you already have, or if it spawns during an event, when they are far more common. * A shiny Pokémon in the wild. Some exceptions to this include the encounter following a raid (when the catch is guaranteed with your first Premier Ball, provided you land it), and during events such as Community Day, when shinies are far more common. Ultimately, it’s your call what you decide to use a Master Ball on. If you decide to use it on a Pidgey, go ahead — we’ve all been there — but we recommend saving it for an encounter with a Pokémon you would not want to live without. Can you miss with a Master Ball in Pokémon Go? Finally, one question that might come to mind is: “Can you miss with a Master Ball?” The good news is no, as a special animation will play as soon as you activate the ball. This not only means you will definitely catch your target, but brings a little more fanfare to the occasion of putting the Master Ball to use. You can watch this in action via PokeMiners on Twitter: [Media: https://twitter.com/poke_miners/status/1660380961387737090] Additionally, as shown in the above video, you will get a prompt before you use the Master Ball — meaning it will be difficult to throw one by accident.
