数学クイズ なん度？

So it’s great if you know the answers. Makes you feel really smart. However, the clues are not helpful. The two I’ve looked at so far have been inaccurate or incomplete. And at some point you should be given the option to see the solution with an explanation. Otherwise it’s simply a way to feed your ego. You won’t really learn anything.

BEWARE! The “development” behind this app is practically nonexistent and the people are unethical crooks . The game itself isn’t much. There are three categories: Angles, Areas and Sequences. Every “puzzle” is just a static image of a shape on a grid or a list of numbers and you have to type what you think the angle, area, or next number in the sequence is. This could easily have been a website rather than an app. A very simple website. A mediocre website. The worst part is that the in-app purchases don’t actually do anything. More on that in a minute. First you need to know that this app is just an “advertisement delivery system”. Advertising money is this app’s only raison d’être. The ads are everywhere; at the bottom of the page, every time you start the app. If you swipe away from the app or your screen goes off, the entire app restarts itself to give you a new ad. The volume gets turned up, too. You can’t put your device down for a second without another ad popping up (on top of the ever present banner ads). Go back to a previous screen? Ads! It’s the laziest excuse in the name of “education” and “puzzle game” ever thought up just to pump you for ad money. Just slapped the image on there. “Here. Solve this.” There is an in-app purchase to remove the advertising. $2.99. Pay it and nothing happens. The app remains the same. The ads stay in place. If anything it gets buggier because now certain parts of the app deep in the settings crash when you try to look at your payments or email the developer. Their website is completely in Japanese. I Emailed them anyway. It’s been months and there is still no response.

Nice app

I love this game and how challenging some of the levels are. It helped me study for my angles test. It is also fun with all the colors and you can write on the screen with your finger to solve it! So that makes it much much easier to do the work for the problem. Keep up the great work!

1. The most recent update deleted progress made through the angles problem sets, requiring a restart from the beginning. 2. It would be helpful to allow users to choose more challenging problems, rather than forcing us to progress through the easier sets, which can be excessive and boring. 3. The hints should display geometry theorems so users can better test skills; as is, the hints aren't useful. 4. Overall, I enjoy the problems and find the app a fun way to keep math skills functional to some degree.

Was looking for a game to challenge my idle mind.

Unlike most, I enjoy math and this is a very enjoyable app for me

This is great teaching tool. Thank you. One thing though it would be even helpful if you can randomize the questions. Same drill with different numbers.

This game helped me understand how to solve triangles and gave me extra practice!
