  • A challenging yet fun game Dec 31, 2020

    By Toontown man
    As the title states, the game is incredibly fun and challenging. Makes you think logically and can be very hard. Most of the low ratings are about ads, and I’m not sure about how it was 3 years ago (Which most of the one stars are from) but as it currently stands the Ads are not horrible. You have a permanent one at the bottom of your screen, and you get a short 5 second ad anytime you fail, as yes it’s only when you fail. Personally I don’t think that’s a bad system, in a way it rewards you for beating the level. Probably one of the best free games I have played.

    It's a dope game and it has increased my reflexes and also made my brain more sharp. This game has also increase my hand-eye coordination and I would recommend this game to everyone.
  • Great Potential, but seriously with the ads? Jun 8, 2017

    By Phoenix Witch
    This game has great potential with different variety in game modes and the gameplay itself. It is a nice little brain teaser to train your brain with if you are bored. It is a nice and simple game, but I will not give it 4 or 5 stars because the ads are absurd. Not only do you have an advertisement while you are playing, which is fine for a free game, but you also get an ad every time you die. It gets annoying and it turns me away from playing the game. If you think that you could just get away with just not dying it does get challenging at points, where more like than not you will die. If you don't want a game with a crazy amount of ads, don't get this. You want a good puzzle game for free and you don't care about pop up ads, go for it!

  • Fun and challenging! Dec 4, 2020

    By Sophiesuelou
    I’m picky about games I like. I have a hard time getting into them and not losing interest right away. I really love this game because it challenges both my eye hand coordination and processing the little bit of information. It seems like it would be much easier but it really isn’t and I like that. I’ve been sick and there’s only so much Netflix I can watch, Facebook I can scroll through, etc., and this is a great break.

    Absolutely amazing game, I play it on my Nintendo switch and it's a terrific challenge for like-minded people who want a fun game that's a brain teaser
  • Great game play Jun 14, 2017

    By Fxyvvsgccvhg
    I think the game is quite good, especially for a free game. Anyone complaining about the ads can literally just turn off cellular data and deal with it on wifi, or turn wifi off when they play the game. Sure, this is kind of cheating, but stop complaining about ads you can, in fact, control. Secondly, I do think there should be some additional game play modes, like classic, challenge and etc. or maybe add more levels to the challenge mode, idk, I got all gold on the classic side in three days so maybe some more objectives to complete throughout the game would be nice.

  • Great game!!!! Oct 11, 2017

    By Drkblade115
    This game is great for your reaction time, your hand eye coordination. I enjoy it because it makes you think, it's not just a game. It is but it makes your brain work. It helps pass the time to. On the bus, in the car, on a plane, or on a train. It will make the trip to your location faster and better. I play this game every day. And I set a goal to reach a new level. It motivates me. I defiantly suggest people to this game. It's really fun to play.

    By Noneyourbizzz62738
    I love this game so much, it's an awesome brain teaser, and I don't know why, but when I die/lose I smile instead of rage quit. This game is so fun omg thank you for creating it! Also, I see a bunch of people complaining about all the ads, I simply turn on airplane mode. Easy fix.

    Keeps you on your toes! A good little puzzle for down time - requires focus but just for a little while through the level. The ads really aren't an issue and you can pay the .99 if you really don't like them and want them to stop (or turn off your wifi, etc)!
  • Good but many ads Dec 9, 2020

    By trippidy bippity
    Good game but an ad every death is pretty crazy. Also, the levels for me at least get a little too hard and I just can’t do it anymore. Having to get the gold with many levels and having to complete everything is very hard.

    This game has been the cause of my headaches, for a good reason. The graphics are simple, the gameplay is simple, it all comes down to how fast your brain can process instructions. I do wish that for each level, the first time you unlocked it, it would tell you what's different and what you should do this time. It saves unnecessary death the first few times. Also, how many times do you need to play the third-to-last and last level in extreme mode to get a gold cube?
  • Eh Jun 16, 2017

    By T_sa888
    I'll give it four stars because the game itself is great BUT the ads are brutal. I have to open and close the game several times before the ad that pops up will let me close it to get to the game. Needs to be fixed or I'll be deleting the game.
  • My mind is melting... May 10, 2018

    By MeCa$h
    Really good fast-paced puzzler. My mind is on edge every moment I’m playing, and I always seem to think I have much less time than I actually do. The colors get especially confusing... My one gripe is with the ads. That’s it.

    Lol im noisy when playing this its a nice challenging reaction time test and also a brain buster. The sounds are good, its good and peaceful and it just makes it better with head sets, ear buds, airpods earphones... (idk the word im going to say) its pretty funny for me when i get the wrong one xD. And my only prob y 4 stars is the ad banner its disturbing bc when its aesthetic then theres an ad:/ plz remove that. Anyways i recomend these people gonna test their reaction time and stuff:)

  • Ads infinity Aug 6, 2017

    By VarletG
    I downloaded this app, was enjoying gameplay, and the the ads started. Close an ad, select "continue game", another ad pops up, close ad, select "continue game", get another ad, on and on. Became so annoying I uninstalled this game in less than ten minutes. A shame.
  • Great but the ads Jun 26, 2017

    By Wattsey13
    The app is entertaining and even frustrating at times but it is worth your time. The only thing I have to say is the advertisements are terrible. I understand that you need to have them to keep your app afloat but come on.
