Questions and answers
Is Money Wonders free?
Yes. You can start playing right away, without an account. Signing up is free and keeps your progress, and PRO is optional.
Who is it for?
For anyone curious about how money really works, from teens to grandparents. No finance degree or math skills needed: every idea is shown, not lectured.
How long does a lesson take?
About three minutes: a few interactive slides and a quick test.
Is there an app?
Yes. Money Wonders is on the App Store for iPhone and iPad, and your account works in both places.
Which languages can I play in?
English, Spanish for Spain and Latin America, French, German and Italian. The whole game switches, lessons included.
Is everything true?
Yes. Every lesson is researched from its sources, its numbers are worked out in code, and the demos run real models of how money behaves.
Will it tell me what to do with my money?
Never. Money Wonders shows you how money really works, never what to do with yours: it gives no financial advice. What you do with what you learn is up to you.
