About Lotto Simulation

Lotto simulation started as a simple Australian Powerball simulation app that I added to my personal website.

After sharing it on reddit and getting great feedback, some users suggested more advanced features such as System entries (specific to Australia), more lotteries (Saturday Lotto, Oz Lotto..) which have different rules, have the balls drawn differently etc.

I also decided to add the US Mega Millions, the US Powerball, Euro Millions and Euro Jackpot, as they are amongst the most played lotteries in the world.

Seeing that it was getting a little too much for my personal website, I decided to register lottosimulation.com, which also happens to be a more memorable domain name.

Every now and then I will write a guide answering interesting questions.
