The basic filters on this screen
   are as follows:
   
1) High first number or low last number
   - defined as 1/2 the number of balls.
   Example: For Florida's 6/49 Lotto
   you should not have a first number
   25 or above, or a last number 25
   or below.  
 
2) Lows sums or high sums - defined as
   44% below the mean average sum.
    
3) Minimum gap greater than 3 - in the
   Florida lotto 96% of the drawings
   have a minimum gap of 3 or less.
    
4) Large gaps - defined as any gap 
   that is as large as 1/2 the
   number of balls. 
 
5) Low spreads - defined as 36% of
   the number of balls.
 
6) All even number or all odd numbers
 
7) Sums that are the same as the last 
   draw - in the Florida Lotto 100% of
   the drawings have a sum different
   than the last drawing.
    
8) The sums of the multiplication of 
   the digits, if the same as the last
   draw. This is pretty exotic, but
   it seems to work about 92% of the
   time.
