Start here — one guess
Before you read anything, look at this for 20 seconds and decide what goes in the empty cell.
Don't worry about being right. Guessing first makes the rest of the chapter stick — your brain remembers what it worked for. If you'd rather just be told the rule, skip ahead. No problem.
What you probably noticed: the same shape keeps appearing, and only its angle changes. That noticing is the whole skill. By the end of this chapter you'll see "rotation" the moment a matrix opens.
Pick one. Nothing is scored and nothing is saved — the guess is the point.
The family in one sentence
Rotation: the shape stays the same; only its orientation changes.
If a shape turns to point in different directions across the cells, you are looking at Rotation. If the colour also changes, or the size, or the position — that's a different family (or a compound). Pure Rotation has one moving part: orientation. Everything else is decoration.
The canonical Rotation example: the same shape, three orientations, nothing else moving — a +90° turn each cell.
What Rotation looks like
The same shape sits in every cell. Only its angle changes. Colour stays the same. Size stays the same. Position stays the same.
That makes Rotation one of the easiest families to recognise. The work is naming the pattern inside it — because that decides how you project the missing cell:
- Reading-order — the turn continues smoothly cell to cell, left to right, top to bottom, with no break between rows.
- Row-reset — each row starts fresh; rows don't connect.
- Anti-diagonal — cells on the same diagonal share the same angle.
- Snake-path — the turn reads zig-zag (row 0 left-to-right, row 1 right-to-left), but the direction stays the same.
- Counter-clockwise (CCW) — the same idea, but the angle decreases each cell.
- Row-alternating direction — the angle is the same, but the direction flips between rows (row 0 clockwise, row 1 counter-clockwise).
- Variable step — the step itself grows (+90°, then +180°, then +270°).
- Whole-grid symmetry — there's no per-cell step at all; cells on opposite sides of the centre are rotations of each other.
You'll recognise the family in two seconds. Naming the pattern takes a few more.
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.
Where to practise
The drill serves ten rotation questions you have not seen, easiest first, with the explanation after every answer. The mastery check is six questions — two easy, two medium, two hard — at sixty seconds each, with no tactic on screen and no explanations until the end.
