The Game Corner. Part of every Pokemon game. But in D/P, there is a slight twist that I noticed.
The Game Corner is located in Veilstone City. It is below the Pokemon Center and next house on the left. The house on it's right, is the house where you trade in you coins for prizes.
Talk to all the people in the main place, not the Exchange house. You will get 70 coins so don't waste $1,000 on 50 when you get 70 for free. Go to any slot. (I used last row on the right, bottom) Play it till you get a ball on the bottom screen. Get a Clefary to appear on the bottom screen by getting a bonuses (777 or 3 Galactic Symbols). Then look at Clefary, it will point to the left, right or top. That's the order of they way you should press the slots. So if it points ^,>,<, that's the way you go. But thankfully, if it points ^, you press it then it shows you the next one so you don't forget what the next one is. You get 14 or so turns to follow it and get 15 coins if you do it right. So you could get 210 coins. If you do them right, you get another turn at it. So you could get 420 coins in 2 turns, plus that 100 you got to get the Clefary up there, plus what ever you won before! So you could get 600+ coins if you do it right.
