Or go for one of these gamified math tutorials.

For instance: this one teaches geometric proofs without mentioning the formalism, just letting you "unlock" the tools from a few "axiom" starter tools.

This is very nicely done. I run a training group and I will use this for my students. Thank you for posting this resource.
