Lovely, minimal maths puzzles. Interface is clean and simple, the game is very simple to pick up but consistently challenging and fun. I'm not sure where the complaints of lag come from, I'm on a mid-to-low-end phone and it's perfectly fine.

Good game for killing time. Brain exercise is a plus. Loved it.

Seems to take a very long time to register when your equation is correct. Sliding also seems to not quite work either. On a Nexus 6

Great game but the laggy interface is terrible. Pretty much unplayable. Would buy it if it weren't for this.

Ran great on my iPad, runs so badly on my LG G3 you would think I was trying to run Crysis on a toaster.

Galaxy S5.

Very laggy, difficult to play

lags severely on Nexus 6 stock.

A very interesting game with challenges waiting at every corner

I highly recommend this game, your doing math but having fun, and I didn't think that was possible

It's really interesting when playing with other people because then the game becomes a competition where you have to solve the math problem before the other people. Because of this I found the game design especially interesting with the plan, practice, improvise taxonomy discussed by extra credits on YouTube.

The concept and gameplay are very enjoyable but this app needs some serious work. The interface is unforgivably laggy; totally unnecessary in such a simple app!

Used to run great but now the game lags so bad I don't even want to play it anymore. The devs really need to pick this back up, it used to be one of my favorites.

The application is constantly stuttering. Not sure why but I really want this fixed. It's such a simple application there's no reason my nexus 6 shouldn't be able to run it.

Love the idea, love the size, love how it looks and love the game mechanism. Only issue is that whole interface is kinda squished together and it may be my fault for having a large screened Sony C3, but if you could fix that, this game would be golden. Do need to get my innumaracy in order ha

Good game, but I can't restore my purchase to get the full version.

This game hogs system resources, bringing my whole phone to a stop. Tapping on certain controls is extremely finicky

I love this game but for some reason itbgas slowed to a painful point. Please fix it soon!

Hard... 2number is easy *:D* but 3number need a time to think. I cant imagine how hard the paid version , 4number, 5number and other.

This app lags for whatever reason on my nexus 7 and note 4, really odd

The game is good and addictive, but sometimes just doesn't works, stop responding and the window asking if I want to shuffle the board appears 20 times, so annoying! I hope you guys fix the bugs and improve the game

Really fun game with simple math. Very addictive at times.

I just wish I had more variety with the game. I'm tired of playing with two number combinations. How many levels must I do before I can go to three numbers? I'm on like level 309:-

Shame about the lag

Good game, buggy app

האפליקציה נחמדה, מאמנת את המוח אבל לפעמים מתחילה לשעמם וסתם תופסת מקום, אבל אני ממליצה מאוד!

I love this. A perfect math brain teaser for touch screen devices.

I enjoy it, but the only thing that bugs me is that if I close the app mid-level sometimes it doesn't save the progress. So I could have all the 2's and 3's done and just need 1 more 4, but then I've got something else to do...when I return to the game the level is back to the start

Good for killing time, nice brain exercises, well implemented, good tutorial, you play it right away no wait and you understand it from the beginning. Easy to pause and continue later. Only few ads to their own products, not disturbing to me at least. No permissions required other than in app purchase.

I can spend hours playing this. It really makes the cogs in my brain turn. Only just fits into my tiny 3.2 inch screen. Everyone should try this.

This 2 and 3 numbers are very easy to solve

The trigger for the shake action is hairline - even a smooth bus or train ride triggers the dialog all. the. time. It is incredibly annoying. If there was an option to disable that, or just a button instead, this would be a fun way to pass the time.

Really great, makes you actually pay attention :-)

Hard... 2number is easy *:D* but 3number need a time to think. I cant imagine how hard the paid version , 4number, 5number and other.

It's simple yet interesting.its a really great game more games should be made like this .

Do you know how many levels threre are??

Nice workout for rusty brain

Cool look and feel. Plays well on multiple devices. I use this whenever I'm on the metro.

Bit too. Easy but it's fun. Finally have something I was looking for. Wish u made it a llil more challenging.

lovely game
