## What is Random Balls?

With this app, you can create sequences of random numbers by yourself. Great to use when you need to generate random numbers.

Basically, each ball is bouncing around, collide with other balls and walls along the way, and finally some of the balls will reach 'target points' and they will serve as your result balls.

There're a bunch of different physics-based ball machines in this app, they use accelerometer datas from your device to simulate real world movements and collisions. Each ball machine is well designed with the thought of adding real world random data into the system.

With all of these, they gives you ball combinations, that are high quality in terms of randomness.

Shake and rotate your phone, let those balls collide and mix, put the phone up-right and you will have sequence of random balls. Each ball machines are slightly different to operate.

# Each ball machine can generate up to 20 random balls in up to 100 balls.

# You can group as many as 10 ball machines together

# The final results are only for your references.

## Key features

- Physics-based ball simulation

### 4/5 — Free fall

*2025-01-29*

I really like the app, but please make an option for free fall to have one section  instead of being forced to have two

**Developer response:** Thanks for your comment. It’s achievable: on app fisrt page tap on the pencil button, and swipe left to delete unwanted section, tap save, you will have only one section.

### 4/5 — Free fall

I really like the app, but please make an option for free fall to have one second on your instead instead of being forced to have two

### 5/5 — A Game-Changing App for Random Number Generation!

*2024-07-21, version 4.10*

Random Balls-Shake Them! has completely changed the way I approach generating random numbers. As a frequent user of lottery number generators, I was amazed by the unique concept and execution of this app. The use of physics-based ball machines and real-world accelerometer data to simulate randomness is truly innovative and adds a level of excitement to the process.

Each ball machine is thoughtfully designed and adds its own twist to the user experience. The ability to generate up to 20 random balls from a pool of 100, and even group multiple machines together, offers incredible versatility. The app's intuitive interface and engaging visuals make it easy and enjoyable to use.

The developer has clearly put a lot of effort into ensuring high-quality randomness in the generated ball combinations, which is essential for any application in this space. Overall, I am beyond impressed with Random Balls-Shake Them! and have already recommended it to several friends. If you're looking for a fresh and entertaining approach to generating random numbers, this app is definitely worth a try!

### 5/5 — I won using this 😀

*2024-07-04, version 4.9*

Won £140 matched 4 number on lotto 3/7/24

### 5/5 — 希望加上一个功能

*2024-02-22*

我喜欢玩覆盖型玩法，就是将所选号码不重复的分成几组。但软件出号码后，不能排除已出球，剩下球的继续摇。或者出球数能跟我选的球一样多，然后显示的时候能按多少球一组这样排。

### 5/5 — Atualização boa

*2024-02-16*

Adicionaram mais opções e assim o que ja era bom ficou melhor! Poderiam sempre adicionar outras formas de escolha de números e retirar os mais antigos.

**Developer response:** obrigado pelo seu bom comentário

### 5/5 — 更改

*2023-11-24*

希望再加一个选号窗口

### 5/5 — BEST RANDOM NUMBER PICKER!

*2023-07-13*

HIGHLY RECOMMEND!

### 4/5 — 希望新增一些常用功能

*2023-06-02*

1，希望能把每次摇出来的号码显示在屏幕旁边，或者显示在现有的屏幕下方，多增加几组结果号码显示，可以摇出10注号码来，自己根据结果可随意改一下，然后批量发给彩票站老板。现在的结果只能一个一个复制，有时候想多摇几次，后面就记不住前面出的结果了
2，希望可以新增自己喜欢的幸运数字到结果中，比如说个人喜欢6.8.9可以把这三个数字固定到结果中，其他的3个数字随机摇出来，每个人都有自己的幸运数字

### 5/5 — 小盘太小了，都看不到

*2023-05-28*

小盘太小了，都看不清楚，方盘一定要手摇，把滚动模块弄多点吧，圆盘球会掉出来。

## Frequently asked questions about Random Balls

### What does the Random Balls app do?

This app generates sequences of random numbers through a physics-based simulation. Virtual balls bounce and collide within different machines, with some balls reaching target points to serve as your random results. It's designed to provide high-quality randomness for various uses.

### How does the random number generation work?

The app uses your device's accelerometer data to simulate real-world movements and collisions of virtual balls. By shaking and rotating your phone, you cause the balls to interact. When you hold the phone upright, the balls that have reached target points form your random sequence.

### Is this app free to use?

The app is free to download and use, but it offers in-app purchases. This means you can enjoy the core functionality without cost, with the option to purchase additional features or content if desired.

### What are the limitations on the number of balls generated?

Each ball machine can generate up to 20 random balls. Additionally, you have the capability to group as many as 10 different ball machines together to create more complex or varied random sequences.

### What are some common use cases for this app?

This app is useful for generating random numbers for games, making random selections, or any situation where you need unbiased random data. The physics-based simulation adds an engaging element to the process of obtaining random results.
