RYB

Tl;dr: If you like Minesweeper, look no further, RYB is a perfect game for you!
I'm not mainly a puzzle gamer, but RYB is by far one of the best puzzle games I have ever played. A friend of mine gifted me RYB knowing that I adore Minesweeper, and playing a game like Minesweeper with unique mechanics and colors was a lot of fun.
It might be a little hard to understand the mechanics at first in RYB, but when you understand them, it becomes incredibly rewarding as you solve the puzzles. I haven't counted, but there are many levels that result in pretty long gameplay, and the variety of new mechanics is at a great level.
The one thing that I suggest to new players is to not use the "health points" in the game in order to solve puzzles. The reason minesweeper is so rewarding is that you don't have a second chance, you lose once you step on a mine. In RYB, you have two chances to fail a guess during a level, which I think makes the puzzles less rewarding if you utilize them. I suggest everyone to not use the extra levels the game gives, and to solve all puzzles by utilizing only logic. This is why it took me more than four hours to finish the game, but I had a great amount of fun while doing so.
The only problem I had with the game was that, in certain levels, I couldn't come up with a proper logic that concluded the solution of the level. Instead, I had to use my chances to solve it. I don't know if using the health points in order to solve certain levels is intended, but a few levels frustrated me for this reason. It was not a big deal though.
To conclude my review, I would like to thank the developer for creating such a great game. As I have said before, if you like Minesweeper, RYB is a great game that you should not miss.

Nice and short puzzle game. Ngl, some puzzles I got by chance I feel, maybe I was just lucky but that last last one is weirdly easy, I think there's way harder ones in between the other levels.
Still, 2.5h cute puzzle game

Great puzzle game, no guessing required.
Due to its length and the lack of a notation feature, I wouldn't put it up there with Hexcells and Tametsi, though it is free to play. If this developer made a sequel that addressed these issues and better incorporated all of the game's mechanics into the final levels, I'd definitely buy it.

Really interesting game with a unique challenge. But it becomes complete guesswork once they add the orange color. The guide dots become irrelevant. It will show you a triangle with three yellow dots, which should indicate that everything touching that triangle is yellow. Instead, you'll have the adjacent shapes be two or three different colors.
I still recommend it because it's fun until then.

I am really enjoying this game! It's sort of like minesweeper, but very calming. One critique is that the sound effects can get a little monotonous at times

Sometimes unintuitive, but still really enjoyable.

At times it could really use some kind of marking tool. It was a bit annoying having to keep track of all the different options in my head.

This is a very satisfying puzzle game with some wonderful mechanics for the logic. I only wish it was longer and combined the later mechanics more often. Regardless, I definitely recommend trying the game if you're a fan of tile-based logic puzzles like Tametsi or Hexcells.
