So several sites online state that in order to earn the heart piece, you must make at least 200 rupees. Well I've gotten 184 rupees, and I just received the heart piece. So maybe someone can confirm an even lower number?
when i did lorule's rupee rush i had 199 rupees at the end i was annoyed at first cause i thought i missed it by 1 rupee but i got the heart piece anyway, so i dont think the amount you need to get is 200.

Remember the solution to Rupee Rush is to line it up with the music. The minigame music has two phrases that repeat, you should talk to the guy the instant the music changes to the second phrase for the second time. Once you have it down, you'll talk to him with less than a second remaining every time for the triple bonus.
This doesn't work if you ever enter the menus or get the Maimai as it will throw you off.
