### 5/5 — Love this game but it has a few bugs

*2023-07-29*

8, 6, 6, 1 is impossible. Also sometimes you will be give. Numbers that require you to make a fraction to solve. Given the rules of the app, those cannot be solved either. Please update the app to remove unsolvable numbers!

### 3/5 — I love this game BUT it needs a patch

*2023-05-26*

I play this game with my whole family. It’s addictive, and we love it. Sometimes, after we get stuck on a puzzle, I’ll use a 24 calculator to see what the solution was. But recently the game gave us a couple of unsolvable puzzles! That’s never happened before, and I don’t know what’s wrong. Also, in the past, sometimes the game might give numbers that technically *could* get 24, but not within the confines of the app (i.e., it would require dividing numbers into a fraction, not a whole number). Please fix your game!

### 2/5 — Can’t turn off the sound?

*2022-01-28*

I would like this app a lot better if I could turn off the annoying music

### 4/5 — Impossible cases

*2021-08-02*

2,3,5,12 seems to be impossible, please remove!

### 1/5 — Good game

*2021-02-17*

Good game for sharpening arithmetic skills.    However, giving one star because there’s no way to turn off
 the music.

### 4/5 — Fun and helps me learn

*2020-09-30*

My teacher showed me this game and I started playing it. They should definitely Add stuff to though.

### 3/5 — No Settings

*2019-12-02*

Very fun game overall, no real issues with that. But there’s no way to off the music, or turn it up or anything of the sort. Gets very annoying very quickly.

### 1/5 — Game seems flawed

*2018-10-09*

Some of the answers requires a fraction and the game doesn’t allow you to use fractions as part of the answer.  For example one of the questions was 3 3 7 7.  Only possible answer that I know of is (3/7 + 3) x 7 = 24.   Game will not allow 3/7 as part of the answer.
