Win the goldenrod lottery.
just go to the radio station in goldenrod and ask the lady on the desk about it. She will check your numbers and give you a price according to this.
The Pokemon lotteries in generations III and IV are random and you can't really maniuplate them. The best thing to do is save before playing the lottery at Lilycove Department Store (Ruby/Sapphire/Emerald) or Goldenrod Department Store (HeartGold, SoulSilver) and keep soft resetting the Nintendo DS or Game Boy Advance until you get the Exp Share. Just don't save on the same floor/room as the lottery, as it's more likely to give you the same result every time.
i suggest action replay or win the lottery
The lottery is the place where you can win rare stuff at like a masterball the number has to match the ID number of a Pokemon ou own.
Win the goldenrod lottery.
In Pokemon Soulsilver, you can get a Net Ball from Johto in Goldenrod City. You have to win it from the Goldenrod Dept. Store lottery.
You have to win 1st place on the lottery ticket thing in the goldenrod city radio tower.
you need to have all numbers of one of your pokemon's id numbers. (Grand prize: Master Ball)
You could get one from Professor Elm, or if your Pokemon have the ID 12345 (if your the 12,345 person to get the game you will have that ID) you could win it from the Goldenrod Lottery Corner in the Goldenrod Radio Tower.
Unless you literally win the lottery in the goldenrod radio tower, then yes, you only get one.
There is no code. Either win a lottery at the Lottery Corner in Goldenrod City or Beat Clair, get her badge, receive a phone call from Professor Elm, go visit his lab and take it from him.
you can't but you can use action replay or game shark or win the lottery in a building in goldenrod
Because it is possible to win, and people want that chance, no matter how slim it'd be.
Sorry to disapoint you, but winning the Lottery does not get you a Master Ball in SoulSilver- I should know, I won once using a little trick I found ;) You only get a Max Revive.
you can get a masterball by prof. elm or get the big prize at the lottery in goldenrod (you must be very lucky to win so do lots of trades at gts)
Professor Elm will give you one after you've defeated all the johto gym leaders, and if you win first prize in the goldenrod lottery corner they will give you a master ball.
