FAQ

Does this tool predict winning numbers?

No, this tool only calculates the mathematical probability of winning based on game rules; it cannot predict or influence future drawing results.

How are the probabilities calculated?

Can I calculate odds for games not in the list?

Yes, select the 'Custom Lottery' option to manually input the number of balls and the range for both main and special numbers.

Are the results guaranteed?

The results are mathematically accurate based on the parameters provided, but they represent theoretical probability, not a guarantee of winning.

Is this tool free to use?

Yes, the Lottery Probability Calculator is a free utility tool available for anyone to use without registration.
