I hear and I forget; I see and I remember; I do and I learn.

– Chinese proverb

We believe learning by doing is one of the most effective ways to master a new programming language. Learn sCrypt is a series of lessons that split the development of an on-chain game Tic-tac-toe on the Bitcoin network into interactive chapters. No prior sCrypt knowledge is needed. By the end of the course, you can build a fully functioning Tic-tac-toe with an integrated web frontend and play it using an existing wallet.
