The reason we want to know things like whether or not you live in the USA and what school district (if any) you attend is because we have math leagues and competitions here. Basically, you will play our games and, if you decide to tell us what school district you're from, you can compete against other students in the same school for the highest scores on our games. We also will let you know if you're the highest scorer in your county, state or nation.

Because the vast majority of our students are from the US we have only implemented this feature for US residents.

Also, if you do not belong to a US school district (maybe you're a home schooler or maybe, like myself, you're not in school any more) you can join one of our other leagues.

Lastly, if you'd like to remain anonymous and not show up in the high score tables results, you can change your privacy settings after signup.

We ask you for your zip code so that we can include you in the high scores tables for your region--your city, county and state.
