also two tips on catching I saw:
overview for LulusPix
Catching Pokemon:
The game does a really poor job at explaining the catch system and how to get "bonus" likelihood of being successful. After catching hundreds of pokemon I have figured some things out.
First off, the circle. When you tap and hold your pokeball a circle will appear within the white circle which is the pokemon's hit box. The colour of the this circle gives you an idea of how likely you are to catch this particular pokemon. The circle will range from Green (easy) to Dark Red (very very hard).
Improving your chances:
The easiest thing to do (if available) is to use a Razz Berry and a high quality ball. The Razz berry increases your success chance on a capture for ONLY the next hit. The high quality ball is pretty self -explanatory.
You'Tll notice that as you hold down the pokeball the circle will get smaller and smaller until it resets and becomes as big as the white box again. This circle getting smaller is a double edged sword. If you are able to toss your pokeball through that circle you will get a bonus to your capture chance. If you toss it when the circle is big you'Tll get a small bonus. I you toss it when the circle is tiny you'll get a big bonus. BUT! You have to get it through the hole so unless you are very good at aiming you will miss the small hole and get no bonus at all when you could instead get a small bonus.
You'Tll know if you got a bonus because there is comment on the pokemon. For a small bonus it will say "oNice!"? and for a large bonus it will say "oExcellent!"? with "Good"? and "oGreat"? in between.
You will also gain bonus XP for performing a bonus chance catch. Putting spin on the ball also gives a very small amount of bonus chance and gives you a "oCurve ball"? bonus of 10 xp.
How to throw your ball:
Most people will do a lob throw. Holding their phone straight up and down (or close to it) and plopping the ball on the pokemon from above.
This throw is fine most of the time. It is a very forgiving throw because you can hit them anywhere from the toes to the top of the head and it will count as a hit.
However! Eventually you will run into some big mean stage 3 evolved pokemon who will actively repel pokeballs or the pokemon will back away from you farther than the lob throw can reach. Perhaps you've already seen Zubats do this to you.
When this happens you have to use a "oLine drive"? throw.
You perform a line drive by tilting your phone to be closer to horizontal about 30-45 degrees above horizontal. The velocity that the ball is released at depends on how far you drag your finger across the screen. So to optimize this distance you want to run your finger diagonally across the screen. Aim the corner of the phone just above your target'Ts head. You should barely be able to see the edge of his image. Then quickly run your finger across the screen and you'Tll toss a pitch that these tough pokemon can'Tt deflect and really get that ball out there to far away pokemon.
I would recommend practicing this throw before a legendary pokemon or ultra-rare pokemon shows up.
