Create a private leaderboard for your friends, school, university, workplace...
Accessible for all - if you're a high school or college student, you should be able to attempt and solve all of the challenges
If you're struggling, help will be available via social media and solutions will be visible once the week has finished - though submissions can be made any date!
The larger the community becomes, the more fun taking part in the weekly challenges should be - feel free to share the site amongst your friends, classmates, colleagues, social media groups etc!
Good luck - and have fun!
