After playing, stay a little longer
Use Review to find the move that changed the outcome, visit Tool to learn when it applies, then try the real-life challenge. You also learn when you discover that an old approach no longer works.
Do I need to study the theory first?
No. Start with the goal and rules. If you get stuck, reveal hints one layer at a time. The tool guide is available whenever you need it.
Does winning mean I have mastered the tool?
Winning alone cannot tell you that. In real life you still need to identify the problem, test assumptions and observe results.
