What is the maximum score one can attain for all non-infinite levels of the Head it Pokemon Amie game?

Question

In other words, what are the maximum scores you can have in the easy, normal and hard levels of Head It?

Answer 1

So, you too are playing Head It to maximize the hearts of your Pokémons, like me ? :D

If you are talking about the scores that you need to get stars, then they are listed by Serebii:

Point Table
Rank	Easy	Normal	Hard	Unlimited
None	0-19	0-19	0-29	0-49
★	   20-29	20-34	30-49	50-99
★★	   30-39	35-49	50-69	100-199
★★★	  40-99	   50-109	70-129	200-399
★★★★ 100-199  110-219	130-239	400-599
★★★★☆ 200-299 220-329	240-349	600-799 (4 stars and the half)
★★★★★	300+	330+	350+	800+

But if you are talking about the maximum high score, then, like in most of this kind of minigame, it is either 999, 9999, 99 999 or 999 999. But I doubt it can exceed 1 000 000.
Sorry for the inaccurate answer ^^
Hope this helps ! :)
