How can I get more than one Exp. Share in Platinum?

Question

I heard you can get more than 1 exp share; but not how and if this can overlap. How would I get the other exp share and can I use the method again?

Answer 1

The first Exp. Share is from Rowan’s assistant on Route 206 after having seen 35 Pokémon. You can get a second one from the Lottery Corner located in Jubilife TV, but it is very rare as it requires you to have 3 digits of the daily number matched.

The Lottery Corner method is renewable, but again, very difficult.
