The Method
Eight families, eight chapters
Almost every matrix reasoning question belongs to one of eight reasoning families. Learn to name the family in two seconds and the solve is most of the way done. Each chapter opens with a question to guess at, names the family in one sentence, then teaches the tactics, works three questions, and hands you a drill and a six-question mastery check.
Chapter 1 is open to everyone, in full, with its drill and its mastery check. Chapters 2 to 8 open their lead-in to everyone — the guess, the family in one sentence and what it looks like — and keep the tactics, the worked questions, the quiz, the cheat sheet and the reference card for full access, together with their drills and checks. Full access is $29 once for 12 months, with a 30-day refund. Since 2026-09-21 the drills, the checks and the paid sections live in the Matrigma Prep Course; these pages are the open way in.
The course
This chapter is a lesson in the Matrigma Prep Course
The course carries the same eight chapters as ten pattern lessons, each with a guided think-through, a drill of unseen questions and a quiz, plus the full practice tests and your readiness report. Enrolling is free; full access opens the paid lessons.
- Chapter 1Open — the whole chapter
Rotation
The shape stays the same; only its orientation changes.
- Chapter 2Lead-in open
Mirror and reflection
The grid flips across an axis, and handedness is the tell.
- Chapter 3Lead-in open
Movement
The shape keeps its form and changes where it sits.
- Chapter 4Lead-in open
Sequences and growth
One feature steps up or down by a regular amount.
- Chapter 5Lead-in open
Counting and arithmetic
Count first. The rule is a sum, a difference or a total held constant.
- Chapter 6Lead-in open
Combining and overlap
Two cells combine into a third by union, intersection, XOR or difference.
- Chapter 7Lead-in open
Grid logic
Every value appears once per row and once per column.
- Chapter 8Lead-in open
Conditional and rule-based
One attribute decides another, or something is quietly conserved.

Rotation is the family most people already half-know, which makes it the fastest place to see whether naming the family before solving actually changes anything for you. The whole chapter, its drill and its mastery check are open, no account needed.
