Addictive and Challenging

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 game 👍🏻

This is one of my favorite mindless games. I like that you don't get too stuck on the rounds, and you're more likely to complete them than in a game like Dots (which is based completely on luck sometimes tbh). Also, you can mute the music and whatnot in settings. I have a few nit-picks tho:

--As you can see in the other reviews, the ADs are insufferable but can be paid off for $2.99.
--There's now an arrow pointing to the hint button which is rather annoying.
--I just now realized how you get 3 stars in the rounds. As long as your finger stays on the screen, you'll get 3 stars. If you take your finger off the screen once you get 2 stars, twice is 1 star. That's kinda an unfair way of rating. You can spend 10 minutes figuring it out, but as long as your finger stays on the screen you get 3 stars. It should be rated based off of time and not how well you can keep a finger on a screen imo.

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,
