### 5/5 — This is a great game and my favorite.

*2022-08-17, version 1.7*

I t took a long time for me to find a connect the balls game but this is the one that pleases me the most.

### 3/5 — Irritating

*2022-08-14, version 1.7*

Each game takes me about 3-5 seconds to get though. I would like this game a lot more if I didn’t get a pop up asking me to give a good review about every two games. I also can’t stand the constant videos I have to watch between each game. It’s literally the reason I’m deleting this app and will find another one.

### 5/5 — The Best

*2021-07-08, version 1.7*

This is the best of its kind. The mazes are sufficiently challenging for mindful and relaxing play and the advertising breaks were short and not too frequent. Give it a try. If you like it like I do, you can play on. If you don’t like it, you can quit. You will lose no money and little time.

### 3/5 — Might be fun

*2021-06-21, version 1.7*

After figuring out the objective of this game, I tried several games. I was quickly successful at the “easy” level. It seems the game has potential. I like that to be successful, first try (minimum  moves), I have to pause and look to at possible solution. I think it will sharpen my aging brain.

### 5/5 — Great app

*2021-04-22, version 1.7*

I’ve had it for over 2 years now. Just bought a new cell and I have to continue with it. I like the challenge and I need to exercise my mind. And what better It’s free. Thank youuu!!🙋🏻‍♀️👍

### 4/5 — Beginning is too easy

*2020-12-20, version 1.7*

My only complaint is that you have to filter through hundreds of really easy stuff to finally unlock something that challenges you.

### 5/5 — Great game

*2020-01-22, version 1.7*

So fun. So addicting.  Be careful though cause once you start playing it’s extremely hard to stop playing.

### 3/5 — Great game, but

*2019-12-19, version 1.7*

This is a great game, but the ads after every puzzle keep freezing and I am unable to close them leading to me to force quit the app about every 3rd puzzle/ad. Also the primary reason I am rating is to attempt to get rid of the pop-up asking me for a rating that has been happening after the ad after every single puzzle.

### 5/5 — Hard but gradual release

*2019-08-03, version 1.7*

Very good game, visual puzzles build from super easy to hard getting enough practice time among the difficulty levels

### 5/5 — Challenging and fun

*2019-01-18, version 1.7*

I honestly have enjoyed this so far.  I haven't asked for a hint yet, but some puzzles make me think for a long time.  

I would suggest improving the way we have to navigate to another level to a particular puzzle, because it is sometimes tedious to continue where you left off.
