- Not for you? One email within 30 days and you get the $1.99 back.
- What you build is yours.
What this is
desmos wizard is an online course. You build a 3D game using only equations, in the same syntax as the Desmos calculator you’ll use in class and on the SAT. It’s made by one person, @graph.goblin. These terms are the deal between you and us.
Who can use it
The course is for people 18 and older. By using it or paying for it, you confirm that you’re 18 or older and that you agree to these terms.
What you pay for
One payment, shown at checkout in US dollars, unlocks levels 2 to 6 and the SAT extra credit, for as long as we run the course. You get an access code that looks like DW-7K2P-M9QX. It opens every level on any phone, tablet or Chromebook you type it into.
The code is for you and your household. A code that gets posted publicly may be closed, and we’ll send the person who paid a new one.
Refunds
30 days, no questions asked. The details are on the refund page.
What you make, and what we make
The equations, cities and games you build are yours. Share them, post them, show them off. The course itself (the lessons, the levels, the art, the goblin and the code that runs it) is ours, so please don’t copy it or resell it.
The calculator
The course runs on its own graphing calculator, built for this course. It uses the same syntax as the Desmos calculator, but it isn’t Desmos and loads nothing from desmos.com. desmos wizard is independent: it isn’t made, sponsored or endorsed by Desmos Studio PBC.
Being decent
Don’t try to break into the site, share codes in bulk, or use the course to hurt anyone. There’s no chat and no way to message other people inside it, on purpose.
No guarantees
We work hard to keep the course running and correct, but it’s provided as is. As far as the law allows, the most we can owe you is what you paid us. If something is broken, write to us first. We’d rather fix it.
Changes and contact
If these terms change, the new version goes on this page with a new date. Questions about anything here: support@desmoswizard.com.
