It is a collection of "Mini-games" with simple and colorful anime style graphics.
You can choose from 3 mini-games:

1 Falling shapes
2 Swap attacks
3 Slide portraits

PLAYABLE

From the "Menu" you can choose whether to play in "Campaign" or "Free mode" mode, the options do not exist so you can not change anything.
Whether you choose Campaign or Free , once you start the game you can no longer go back to change games , even if you crush "ESC" you have to continue until the words "Game over" come out
The music is suitable as a company while solving the puzzles, but it is always the same and after a little tired and I decided to turn down the volume of the PC.

1 FALLING SHAPES
Play in the "Tetris" style you have to frame pieces of various shapes and colors, if you combine various pieces of the same color these cancel out leaving free spaces, use the flivers to move them and turn them;the purpose of the game is to try to use as many pieces as possible in order to increase the score, but if you get too high with the wall you are building the game ends.

2 SWAP ATTACKS
You have 2 squares that you need to exchange the various symbols on a dashboard, if combined 3 or more symbols these cancel out leaving gaps.
It's not easy because the wall of symbols keeps going up if it gets to the top the game is over.

3 SLIDE PORTRAITS
Here you will find 5 characters of your choice to rebuild, they are broken down into 15 squares, to relaunch the puzzle you can not exchange the tiles with each other , but you have to arrange them simply by moving them on the bridge, to help you are numbered from 1-15 so you already know which piece to take to place in the right place.

CONCLUSION
Overall as Minigames are made well, pleasant as pastime, and practical to play.
The only bad thing is the brevity of Game 3 are few, let's hope they add more later.

-No options whatsoever
-No way of making the game windowed
-Game is clearly unfinished
-Artstyle rips-off Nichijou (and some of the characters, including Nano and Mai)
-Very little variety
-Game doesn't display properly on my 21:9 screen
-Generic music
-No way of pausing the game

Only good thing about this game is that at least there are no Mio and Yuuko rip-offs. Thank goodness.

If you're a puzzle fan or a Nichijou fan, trust me, this is not a game worth getting, even for the LOLs.

Overview:
is not worth attention

this game killed my dog

I have spent 3 hours of my life on just the sliding tile puzzles and now I can solve them in a minute, got help me.

Puzzle Challengers is a blend of a couple of different kinds of minigames (Tetris ripoff, sliding puzzle ripoff, match-3 ripoff) with a high school anime club dropout MS-paint/pixel art style. It's unpolished and quite unpleasant to try playing. On the upside, it does seem to have been a sincere genuine attempt at making a game... only, badly.

From a technical perspective, the game doesn't meet basic minimum requirements that most PC gamers expect as standard.

The artwork here is terrible, it's a blend of old retro pixel "art" used as a substitute for contemporary PC graphics, and some of the most amateurish MS-Paint style drawings (I won't deign to call these "illustrations"). It's unclear if this is due to lack of budget to arrange someone who can do graphics properly, or lack of talent, regardless, the overall visual quality of the game is extremely low as a result of these decisions.

There's no options to change the resolution for the game or customise the graphics settings. There's no way for gamers to ensure this is running at the native resolution of their displays... there's no guarantee this game will look right on any PC as a result of this hamfisted design decision. There's no way for gamers to try improve the low quality graphics. This is worse quality than your average Java/Flash game.

Bewilderingly, the game doesn't include proper audio controls, so you can't turn off the annoying background music, you'll need to alt+tab out and stop the music using the Windows sound mixer. This is obviously not okay and it's unclear why the developers chose not to include this basic feature.

The controls can't be customised, which will be an annoyance for many, but it can also render the game unplayable for differently-abled gamers.

These technical defects push this game below acceptable standards for any modern PC game.

Puzzle Challengers is relatively cheap at $1 USD, but it's not worth it given the defects and shortcomings with the product, especially considering the sheer number of completely free, much higher quality games on Steam. You can play all these kinds of minigames free on the web or on mobile, with higher quality. It's impossible to recommend anyone pays for this.
