Have fun with this utility. To begin, you must enter the frequency in seconds so that the numbers randomly come out among themselves. When you start, the application will begin to show random numbers and read them (through the device's speaker). He will place them on the board in the respective square, which is arranged for 50 numbers. The draw can be stopped at any time.

Having the .AIA blocks, you can change it for many utilities, for example, convert it for a bingo, lottery, among others.
