Terms of Use

Solver Society is free to use for learning. Here's what that means, plainly.

What you may do

• Use every lesson, Mission, and challenge for your own learning — free, no account.
• Teachers and parents: print and hand out Missions to your class or family. That's what they're for.
• Share links to any page or video.

What we ask you not to do

• Don't sell our worksheets or repost them as your own work.
• Don't copy the characters (Bandit, Sunny Bun, and friends), the artwork, or the site design — those belong to Solver Society.

Videos

Our videos are hosted on YouTube, so YouTube's Terms of Service also apply when you watch there.

The honest fine print

We work hard to make every answer right (and when Bandit gets one wrong, it's on purpose — that's the game). Still, the site is provided "as is," without warranties. If you spot a genuine mistake, please tell us — we fix things.
