Hi~

I create this guide to help people to clear the game with more ease, without lowering difficulty, as it is a requirement for an achievement in the game. This is just a compilation of tricks, tips and advices based on my own experience while playing Purino Party. I hope it will help !
Like & rate if you find it useful :3

P.S.: English isn't my mother tongue, so you may find some language mistakes here and there :v

First of all, you want to know (if you don't already) that in this game, the "tiles" or puzzle bricks can be moved in every direction you want, not just on a left/right axis or up/down axis.
You can take a tile (by selecting it and holding the LMB) and move it where you want, this is not like HuniePop where you can only move horizontally or vertically. It is important to know that and take advantage of it.

Second thing is, you can hold the LMB for a certain period of time, and doing this will allow you to make a whole lot of moves with your selected tile. This is very important because it allows you to "prepare" various lines of matching tiles BEFORE releasing the one you are holding. This is the mechanic that is the most important to make big scores, so, practice this technique as soon as possible to get used to it when the game become challenging !

This one isn't that obvious, and it's the reason why I write this guide.
On my first hours of Purino, I thought making big big lines of bricks was the best option to get the big scores, so I was like "OMG I'm gonna align those 8 tiles and boom ladies !".
Well, my experience made me learn that this statement is, in most cases, counter-productive. In a vast majority of cases, it is most rewarding to make multiple lines of 3-tiles than a pair of 5-6 tiles lines.
But why ? Because of the combo mechanics, that adds a multiplier after every consecutive lining completed ; it will ALWAYS be better to reach a high combo streak with multiples 3-lines than making small combos with 5-6-7 tiles and more.
You don't have to trust me for that, you'll see it by yourself if you play long enough :)

The "Fever" mechanic is one of the most important to reach the highest scores.

Basically, if you line 3 hearts (or more than 3, but you really shouldn't...), you will trigger the Fever effect during the next move, and gain a nice multiplier for every matching completed.
So it's like : Fever + High Combos = Path to high scores. As simple as that !

BUT you will often see grids where there are not enough hearts to make a line, or no heart at all. Well, it is okay for lower grids, you can succeed without them, but when it comes to make 2000 points or more, you will NEED those bloody hearts to make something good.

So if there are no hearts on the grid, you can just reload your game or let the clock go to zero to retry to save your efforts.

I thin it is neat to say it again, because it is brielfy said during tutorials : each girl has her favorite type of tiles. These favorites tiles will reward more points with every matching, so it's a good thing to work on, to get the best of your grid.

Here are the favorites tiles of every girl :
Yellow Paintbrush : Yogiri & Kagari
Green Music notes : Sora & Hinako
Purple statue-thing : Miyako & Konoka
Blue pencil : Suzu & Kanae

My strategy is to keep them to use with the Fever effect, making them more effective. I suggest doing so if possible, but it is not mandatory to get good scores - but eh, everything that can help, you should use it :)

Skull-type tiles are your ennemies. Or at least, this is what the tutorial says, but it's not always true, and you can take advantage of them in some cases.

Because basically, skull-type tiles are tiles like the others, so they count for your combos, even if they will eat your move count really quick if you're not cautious enough. But still, in many cases you will want to use them as another source of combo. And in that cases, you will want to line them by 4, 5 or more, because each line will eat 1 move, whatever the number of tiles in the line.
So, the idea is : it's better to lose 1 move than to lose 2. So if you want to use the skulls, make long lines of them !

This is about the "visual novel" aspects of the game.

During the dialogs following the puzzles, you will have to select 2 choices of answers to the girl, every time, with every girl after every puzzle.
Good answers = no penalties + bonuses
Bad answers = penalties + no bonuses
With one girl, I realized that the bad answer was pumping up my score to reach to +200 points, this is huge. Reaaally, I can guarantee it !
So, the idea is : get all the good answers during these sequences. If you don't, just reload your game. Yes you'll have to redo the previous puzzle, but it will save you some efforts in the end. And believe me, you don't want to get to the point where the 5-star challenge requires 3000 points (I had this with the painting artist, took me 3 days to get over it -_- )
And the bonuses, they can vary but it can be : additionnal moves/additionnal overall time/ additionnal time when holding a tile... This is neat really.

So obviously, trying to get all good answers will require many many saves, so I suggest you to save your game after every successfull game/dialog, in order to reload if you fail a question after that. It's just a habit to get used to, but it's definitely worth it.

Now if you combine all the tips I gave you here, you have all the keys to go through the game, without touching the difficulty.

Of course it will still be an affair of patience, because you won't always get a good starting grid to work on (this is where the RNG can be a bit frustrating), but after some unsuccessful tries, you will eventually have a grid with enough hearts, girl's favorite tiles, and a minimum of skull tiles, which is more of an ideal scenario to work on.

I wish you good luck on Purino Party (and really, get the X-rated patch, then the game will be wayyy more rewarding ;) ) !
