Very responsive developers!

Two days after leaving a review about app crashes, the developers released an update that fixed the crashes. This could be a coincidence, but a few other reviews mention how active the development team is in fixing issues and refining the app. Super cool! It would be neat to have more milestone awards to try and get (like the daily puzzle trophies, but for different difficulties / etc). Also, I would love to be able to use my coins or graduation caps to buy different skins for the puzzles or permanently unlock new features / ways of playing / skins. Just a suggestion! I'm a new daily player and adore the function of this app.

The Levels of Difficulty Seem To Be Confused & Events Impossible

I’ve waited about a month before writing this review to make sure I had really experienced everything. While the gameplay is fun (provided you like math puzzles of course), the difficulty levels seem to be all over the place at times. I had “Expert” puzzles I finished in under a minute, and I had “Medium” puzzles that took actual work and several minutes to solve. The events are also an issue. I spent nearly an hour for several different days trying to complete the postcard or whatever they’re called. Not one time did I actually finish to get a reward, and I’m a completionist/perfectionist. If you have to spend over 5 hours to finish the event, any fun is long gone, and it feels like a chore. Overall I’m sure there are other similar games with a much more reliable game. Follow-up: I just got an email and it was talking about more questions about their premium service. I didn’t even know the game had a premium service, and I never asked them any questions about it. It says it’s from a team member, but I’m fairly sure it’s an automated email considering it has nothing to do with what I wrote in the review. I wish I could change it to 0 stars, but I is the lowest it goes.

Love the game but…

I love how challenging this game is. It gets the gears in my brain working - plus there are equations/combos I never would’ve thought of! However, I have two problems with the app: 1. What do I spend the coins on? I’ve searched all over the app and the app’s entry here in the store and yet, I can’t find anything that says what you can spend coins on. So for now, I’ll just collect them. 2. The excessive and lengthy ads are getting annoying. I usually don’t mind ads but it’s gotten ridiculous! For one thing, they’re often longer than each game. Especially when you have to watch the full 1 minute “here’s what you can do in this game app” but then have to wait another 15 seconds of just a screenshot with the game’s app store entry popping up be fore the X to leave the ad appears. Also, what’s the point of having the “skip ad” option after a few seconds if you still have to wait before the X to leave appears? For the 3x coins ads, I sometimes have to watch a second ad just to get the bonus. Not to mention that after I’m given the 30 coins, ANOTHER AD IMMEDIATELY STARTS! As I stated, I usually don’t mind ads and I get why you have them, but the length and amount is ridiculous. If possible, please fix this.

Enjoyable game —- too many ads

Like many reviewers, I enjoy playing these math games very much! However, the advertisement situation is getting out of hand and it’s affecting enjoyment of game play!! When tapping “continue,” too often tapping the (x) to exit the advertisement, my browser to “purchase” the product is accessed. Going in and out of the game several times before the ad was stopped and game play available to resume. Lately, after completing a game, I do not have the option to “continue “ and view shortened ads. There is only the option of the “ad claim x 3” option. This dramatically slows game play and exponentially decreases my enjoyment of the game. I have tried closing out of the game and/or shutting down my device to try to reset the “continue” for shorter ads option with no luck.

A few things that can be fixed …

I always want to open a chest, and you have to complete 20 puzzles first. It takes some time to complete the expert levels , and sometimes even the hard ones! I think that maybe this game could do less levels to complete to open a chest or make it give you a chest when you pay 5 coins in the game . Also think about little kids who want to play the game doing easy or medium mode . They might take a long time to get a chest unlocked because you have to play 20 times! In this game , sometimes when u open up the game, it just closes it right away . But it helps you learn math because it can make u learn division, addition, subtraction, and multiplication! To me it’s a great game otherwise the problems.

Someone cares

Just got the game today. I Have tried many brain games and can say that fast forward on ads is perfect plus (so far) ads start muted. Excellent!! Thank you for a very playable and challenging game. I will play for awhile to make sure I’m addicted to the play (likely) and I’ll buy the ad free version. Why? Someone at this game company has shown that they care about players and do not abuse them with ads that just peeve you to the point of just deleting the app and moving on. I highly recommend this game as good playable ad based games are few and far between! Congrats from me!

I don’t like this design

I don’t see any good reason for them to combine puzzle size with difficulty. Example: easy puzzles seem to be tiny and have few missing numbers. If I’m actually doing math, it’s very easy to work out what the missing numbers are. But then the puzzle size is so small I don’t actually get to practice very much, which is what I really want. If I jump up to medium difficulty, the puzzle size is better, but now there are too many missing numbers so I need a pencil and paper to sort out what the right solution is. My opinion/skill might change if I played this for a while, but I’m deleting it: There’s no way I can get into a groove playing this game…Bad design with difficulty… and also way too many ads.

Ads app and puzzles are weak -I’ll explain

I’m sure there are reputable versions of this game. It’s probably an app that has more than just this one puzzle type. THIS app is just an advert app. The actual game is very basic with 4 levels and after one time playing each level up to expert and 10 games playing expert I was finishing puzzles in about a minute. Then after EVERY. SINGLE. GAME. an ad would play and to skip it, you have to: 1. Sit thru 10 secs of an ad. 2. Hit skip button when it comes up after 10 secs (and that’s if the skip isn’t hard to see). 3. Hit DONE because it automatically takes you to the game in App Store. 4. Wait another 5 seconds for an X to appear to cancel the ad again (again sometimes it’s hard to see). 5. Then hit the X. 6. Then hit done again after it takes you to the App Store AGAIN. 7. AND THEN you can play another game on expert level that may take you not much longer than a minute if your lucky. Go find this type of puzzle in a legit app. I’m JUST as mad at Apple for allowing these type of Apps. I will be reporting it. AND I’m saving this review in a Note AND keep the game so that each time it updates, I can resubmit this review.
