I would like to share with you a lotto 6/49 prediction method, that can raise a bit the probability to guess the winning numbers on the next draw.
It is based on the intervals of the numbers, eg the number of draws between two appearances of the same number.

Suppose the number 1 appears after 7 draws, we write 7 as first number of the sequence, then same number 1 comes after 8 draws, we write 8 etc.
By this way we can build the sequence of intervals for the number 1, it looks something like: 7, 8, 30, 3, 10, 7, 5, 2...

The goal is to obtain a mathematical equation, so we can build the intervals curve, using a sequence of numbers, that we already know.
For example, using the sequence 1, 2, 3, 4, 5....

I spent a lot of time, analysing the databases of the most 6/49 lotteries, searching for suitable equation, to reproduce all intervals curves for the 49 numbers.

Below is the equation:

Y = a + a3*sin(a4 + c1*cos(b1*X+e1) + d1*sin(b2*X+e2) + c2*cos(b3*X+e3) + d2*sin(b4*X+e4)+c3*cos(b5*X+e5) + d3*sin(b6*X+e6)+c4*cos(b7*X+e7) + d4*sin(b8*X+e8)+c5*cos(b9*X+e9) + d5*sin(b10*X+e10)+c6*cos(b11*X)+e11 + d6*sin(b12*X+e12)+c7*cos(b13*X+e13) + d7*sin(b14*X+e14))+a5*cos(a6 + c9*cos(b17*X+e17) + d9*sin(b18*X+e18) + c10*cos(b19*X+e19) + d10*sin(b20*X+e20)+c11*cos(b21*X+e21) + d11*sin(b22*X+e22)+c12*cos(b23*X+e23) + d12*sin(b24*X+e24)+c13*cos(b25*X+e25) + d13*sin(b26*X+e26)+c14*cos(b27*X+e27) + d14*sin(b28*X+e28))

If we give a values for X as 1, 2, 3, 4, 5, 6, 7, 8, 9... the Y result will be a curve, very close to the intervals curve:
Coefficient of Multiple Determination (R^2) = 0.9874443055

Since we know the intervals curve of the number till its last appearance, the goal of the next step will be to attempt to predict the next point of the intervals curve,
using the curve we already built with the above equation.

Let's see for example, we know the last 10 points of intervals curve of the number 1:
it will looks something like 1, 4, 12, 31, 1, 1, 2, 1, 2, 10

Well, now, lets build our curve using the above equation, giving a values for X = 1, 2, 3, 4, 5,......... 100 000 (exemplary)
After getting this work done, lets compare the 10 points of the intervals curve with every set of 10 points of our curve, evaluate the Correlation function for every 2 compared sets,
and find the set of 10 points, that best matches the 10 points of the intervals curve.

The 11th point of our curve will match the next point of intervals curve in 3 - 7 % of all cases.

This is definitely a bit better than random guessing, but still not enough to break the huge house edge of the lottery.

Have fun and good luck!
