Community Insight:
The game is so fun and we thinks it makes us smarter to.
Its great overall but we wish there were a few less ads, but this definitely helped us get better at this.
This is a great game, but is extremely hard for kids.
We enjoy the game, but there are way too many ads in the free version.
We were able to have a great time playing this game. It is super stress relieving, and really easy to understand. We also used it to easily annoy our friends. 10/10 would recommend.
Im a huge fan overall! Ive been playing this with physical card decks since we were a kid, but have been looking for a good digital alternative for a while. However, we do wish there was an undo button so that you can only undo one step of the calculations instead of having to completely start from scratch, but its still great overall :).
We were in a tournament for school didnt win but we loved the game. This app will make you better at your math facts like addition, subtraction, division, and multiplication. Here are some cool things about app: No Loading Education but fun Start as a baby and level up Has undo Also has speed level There is a hidden leader board (to add competition) The app also recommends other apps Has tips if you are stuck If you dont know how to play there is a guide Here is how to play: There are four numbers on the screen, with those numbers you have to make the number 24. You can divide multiple subtract or add. For example lets say we have the numbers 6 3 4 2 we could do 3-2=1 then 6×4=24×1=24 Note: No number can be left.
OMGosh, its amazing.Hope to see more fun features! Of course, we recommend this app! Fun and simple, its the ultimate test for your brain.
This app is so amazing you can make 24 and so many different ways we never knew you could do that it is so fun and it helps you do your math in school or in general and its free but there is a tiny bit of ads but not at all like popping up in your face its so good you should totallyGet this so if youre in math and you love to learn like us you should totally get this game you can do it like in a car and in your friends house or just in your bed and it is really difficult Im only on Junior and we played this like for a month but Ill love it and we think you should totallyGet this24.
We love this game in our classroom our high score. Was 44 and we were really proud and. This one is like the one at our school but it has. Long ads.
We love this game, it interests us and its so fun to play when offline! We are at the baby level and when we try to watch the adds to go to the next level, pupil, it says we have no internet even if we have full bars. We deleted the app, still didnt work, we restarted our ipad, still didnt work, we turned our wifi on and off, still didnt work! Are there any ways to fix this bug? We want to keep playing because its awesome though.
We mean like every 3 stages you get an ad and to get to the next stage you need 2 ads.
Best app ever it doesnt yell at you.
We love this app it helps with our math it really helps because we are in a math competition download this app if you want to get better at math.
Our kids enjoyed it so much!!! Only problem is ads:(.
We used this while we were at home practicing for the math 24 tournament. The only issue we have with it is there isnt negative numbers or anything to spice it up a bit.
This game is a good way to learn how to make long equations with all the symbols like +, -, division, and multiplication. You have to think really hard about all the numbers, and wether you have to add, subtract , multiply or divide. This game is a perfect way to challenge your brain.
The Most amazing app we ever had.
Thank you for making this app our level is puliped 2.
We recently started and have gotten so addicted!This app has every 24game and they really make you think. Awesome app! Now we have a Feature request: could you make a button to favorite the questions so we can go back to them later? We have been writing down the level and question numbers to do that! Itll be lovely to do it with one click as you grind through.
Everyone has to play fun but challenging game.
This game is absolutely euthymic!!! It is very challenging for the mind and makes us feel smarterer every day!!!!! Us and our friend LOVE it!!! #love #billofrights #xingqiu #livelaughlove #itisnotgojover.
Good: So fun we can use what we know to answer the questions Bad: The timer is so And we cant keep up. We also wish that there were levels like easy medium and hard.
This game is great for learning math but there is one problem. As you can see every time we got a problem right the game gave us an ad which annoys us.
We dont like the two digit numbers pls take away. Our school doesnt do two digit numbers.
This is a very fun game to strengthen your brain so we recommend it.
Math 24 is a great way to learn how to use the word math and you can learn more about math and Im in.
We love this game its so addictive we love math 24 as the cards and it on the phone its so convenient and fun.
We were at the Professor Exam when we were stumped we asked our family who was around us. It was fun and tested your brain so we were excited to level up. The exam however had 5, 5, 5, 1 which was impossible and we looked up the tips and it said (5-1/5)x5 which was 4, not 24. So we think the devs are still coming up with levels or they messed up.
We love this app it really builds our speed in the Math24 tournament, thanks and we appreciate the app developer.
Our mom decided that we should go to the make 24 game club, and the cards were so hard to figure out! We told our mom that we were just trying to figure out the cards but she decided to give us this game called 24 game. Now Im so smart in this game and in the club too.
This is a nice app except sometimes it gives us the same question from a lower level when Im on a higher level. Other than that, we highly suggest it.
In class we had this competition where we compete against each other while playing this game, but instead it was cards. We were horrible or course, but now that the competition has pasted we wanted to get a little better, you may be wondering, why after? Because Im an introvert and Im not good with big crowds and stuff like that. Its a really fun game, really allows you to think outside the box.
Ive been playing this game for a week , we enjoyed it ,some questions are very challenging but im stuck at archimedess giant exam, the numbers are 2, 3, 5, and 12 , we couldnt solve this and we cant continue to the next level. Is this a bug or we just not able to solve that.
We bought this for school and it was amazing after a couple days of playing it we were in a win streak at school it was amazing we kept playing and getting some better in a week we got from a single digit to double digits its a great app you should get it Despite all the bad reviews we still got it because we want to do and Im 10.
Idkdikekfnsjfbosud we#feguvfq iugw2erbg3.
We really love this!! We only have one small nitpick: PLEASE give an option to turn off the input sounds/chimes.
We were in a math 24 finals and used this app to practice and won we would recommend this app.
Math 24 is the best math game ever we play it in school and this version that we can play when Im at home is making us smarter thank you for making this game is so enjoyable.
Joined a school club and was doing absolutely terrible but downloaded this app and in like 1 week we were actually keeping up with the rest of the team!!!!!! Great practice for when you just have to wait or when you are doing nothing.
This app is a fun way to pass your time if you are into math. It is a lot of fun when you are bored and dont know what to do.
This game helped with our math skills and it was free. We recommend this game because it helped with our math.
This app is amazing for kids it helps them learn some math.
This game is so gooooooooood and we love that you can get challenged with some good levels. But, we got to admit that in expert level and further, they are waaaaaaaayyyyyyyyy too hard (they feel impossible) that we needed help from our mom (mommy supa smart). But still, this game is very, very good. The end.
This game is fun, challenging, but the solution sentence often doesnt match the solution that was entered.
This app really helped practice math 24 for school. Definitely recommend this app for anyone who wants to practice math 24.
We would like to say that this is VERY HELPFUL because its a actual game for older grades and not like 1 of those baby games where it says 1+4 and also says pay $20 a month but this game is completely free and there might be like 5 ads every time you play but there are about 10 levels you can beat like the master level, baby level and a lot more. We hope this was helpful and we would tots recommend it.
We bought this app because we are a private tutor and wanted a game to play with our students that would enhance their math skills. After noticing that some of the ads were rated 17+ we bought the ad free version. But the ad free version only loaded on our iPad and not by phone. We are bothered that we needed to buy the app twice in order to have it when other apps stay on the the cloud and do not require two purchases. Especially when this is a kids game. We shouldnt have to monitor what ads play. We deleted it and bought original version. Consider what you are buying it fore before spending any money.
We are going to keep this short,it is not our favorite math 24 app but it is not the worst either so in English we dont really like it.
