How do you get master ball in Pokemon Blue?

Answer 1

First, go to SAFFRON CITY. To get past the guard buy any drink on the last floor of CELADON Mart and give it to him. Now you in SAFFRON, go to the highest bulding in city - this is a SILPH CO.Be careful - this building is full of ROCKETS. Go get a card key on the sixth floor and open one of the locked doors. Behind this door there should be a teleporting square that takes you to the seventh floor, to the place where your rival is . His strongest POKEMON is 40L. So defeat him, behind him there should be one guy and another teleporting square. Go talk to the guy and he'll give you a L15 LAPRAS, yay. Then go to the teleporting square, this one will take you to the 11th floor. There should be some rockets there, but after your rival this should be an easy matter. After them open the next door. There is GIOVANNI. His strongest POKEMON is a L43 NIDOQUEEN. After you beat him go talk to the PRESIDENT and he'll give ya a MASTERBALL!!! Easy, huh? PS:Isn't it a pain to always returning to POKECENTER and back to SILPH CO, so there on the 9th floor should be a nurse, it's easier to health up your POKEMON there than in POKECENTER. PSS: Try to open all doors in the building, because in some of them there should be some cool things. PSSS:Hope you'll like playing.
