Just me! One Voice

I found this playing another game. I liked playing but the ads and the music are very annoying. You can turn your phone down but as soon as the ads pop up the noise from the ads play. They are so annoying that I gladly payed the 2.99 just to get rid of them and I am sure they know if you like the game you will pay gladly. I find if I don’t like a game then usually I hit delete and the annoyance is gone. So I say give it a chance and if you like it like I did pay the 2.99 and enjoy. For me I don’t care for the music it is not soothing. Peace and quite is my thing. Some are easy and some have really gave my brain a go at it. I have used the hints but you know as you play you train your brain and your brain gets to clicking and wow you will find you have the happy satisfaction of knowing you did good. I like the game and love the peace of no annoying ads.

Good concept, but extremely monotonous

Long story short: No insult to the creators of the game, but while the idea is there, there just isn't the difficulty to match it.

From Beginner to Master, the only thing that changes is the size of the board. This would be okay if Beginner started with small boards and Master had extremely big boards, but the size increases so slowly, it feels like you're still playing the easy boards. Even the Dots game on Puzzlerama had much larger boards, and that's not counting all the other gimmicks that game has.

And skill progression is incredibly dragged on: to reach the next difficulty, one must complete half of all the levels from the previous one. Doesn't sound too hard, until you find out that there are 500 levels per difficulty.

I also have this wild claim that some levels are copy-pastes of others, sometimes flipping or rotating the board and calling it a new level, meaning you're not completing them faster by training, you're completing them faster because you've already beaten them before. This means the game becomes easier by accident.

And then there's the issue of the music being cut on completion, which is a major gripe for me. That along with the levels being very easy, means that the music will stop annoyingly for the umpteenth time, and you'll wish you brought external music with you.

Oh, and I've stockpiled the equivalent of ten dollars of hints without any urge to use one. That should say something.

Great Game! Minus the adds though...

I got this game, which so far I seem to love, a week ago per request of my mum. The goal of the game is to fill the box in one line without leaving any holes. The only thing I literally HATE about this game is the ADDS. They are so annoying complete a level ADD use a hint ADD just about to win ADD. We want to play! Not watch some add for something we already bought! Apart from the adds this game is so much fun and it makes you use your brain instead of just lying there playing Minecraft all day long. (We’ve all been there haven’t we?) Anyways I’m giving this game 4-5 stars because it’s so much fun, apart from the adds.
Love, your friendly but truthful rater,
