    * README BEFOR USING THIS FUNCTION  
    * This function is for suppose you want the numbers of your choice like 
    * you have build your own way of random arangement (but honestly i don't remond you to do that it will simply sounds unfair)
    * another or the MAJOR REASON for the existance of this function is: suppose your server goes down and 
    * games are goin on and you have stored the game state in DB OR redis whatever now you want to reinitialize it 
    * then use this function  (or now you are the boss so do wahtever you feel good )
