Start Here: 3 Mechanics That Matter

This lesson is most useful if you already have a Solve invite and want to get sharper fast. It focuses on the 3 mechanics candidates actually miss: question-first triage, fast chart pattern recognition, and combination logic under constraints.

What Strong Solve Candidates Do

Mechanic	Strong move	Common failure
Red Rock investigation	Read the research question first, then save only the 2-3 facts that answer it.	Read every chart and drag too much into the journal.
Red Rock analysis	Label the pattern before doing detailed math.	Treat every line chart as brand-new and miss the shape.
Sea Wolf build	Remove disallowed microbes first, then test trios by average.	Search for one perfect microbe instead of a valid combination.

Use this as the mental model for the rest of the lesson.

How to use this lesson: do each exercise before opening the hint, keep a timer running, and repeat only the sections where your process breaks down. The goal is not to memorize game trivia. The goal is to make better decisions under time pressure.

If you only have one hour to prep, do these in order: Red Rock data triage, pattern recognition, then Sea Wolf averaging. Those three mechanics carry the most practical value.
