## Description

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 container can generate up to 20 lucky balls from maximumly 100 balls  
\# You can combine up to 10 containers together.  
\# You can add up to 10 custom balls.
