Don't blow through your stash on that Golbat. Recover your Poke Balls!
In the first few hours of playing , you're going to waste a lot of Poke Balls. Learning to get that flick just right, watching as the ball bounced off of your critter while it tries to attack you, or missing in an attempt to rock a perfect curveball are high on the list. The failed attempt slowly rolls off screen, leaving you ready to grab another Poke Ball and give it another good toss. Actually, it turns out you can recover most of those lost Poke Balls, as long as you're fast enough!
This couldn't be more simple. Tap the Poke Ball before it rolls off the screen after a failed throw, and that Poke Ball will be returned to your inventory. It doesn't work every single time, but it works most of the time and it makes a huge difference when forced to rely on a limited inventory to catch a Pokemon that is being particularly difficult.
Don't let those Poke Balls go to waste. Get out there and have some fun!
