Beat the challenge.

⚡ The twist

Watch for the hidden cost.

What You'll Learn

🧠 Buying a $20 game means NOT buying a $20 book. The book is your opportunity cost. Here's how to do it: 1. Look carefully at the problem. What do you see? 2. Think about what you already know. Does this remind you of something? 3. Try an answer! It's totally okay to be wrong — that's how we learn. 4. Check: did it work? If not, try something else! You're building your thinking muscles. The more you practice, the stronger they get!
