Rotation

Covers reading-order, row-reset, anti-diagonal, and snake-path. All four use a fixed angular step — only the path differs.

Spot the signal

• Same shape every cell.
• Only the orientation changes.
• No colour, size, or position shift.

Name the rule

"The shape rotates by a fixed angle per cell."

Usually 90° clockwise. Sometimes 45° or 180°.

Execute

1. 1Compare cell 0 and cell 1. Measure the angle — that's your step.
2. 2Compare cell 1 and cell 2. Same step? Confirmed.
3. 3Check the row break. If cell 3 continues the step from cell 2, it's reading-order. If cell 3 starts fresh, it's row-reset.
4. 4Apply the step (and the traversal) to the missing cell.

Eliminate the traps

• Off-by-one — the option repeats a visible cell or jumps two steps.
• Wrong direction — the option turns the other way.
• Row-break confusion — if the pattern is row-reset, the option that "continues from cell 2" fits the wrong rule. Check cells 3 and 6 before you commit.

Takeaway — Three cells confirm step and direction. The row break is where most people misread the pattern.

*How do you know not to use this tactic?* — If the colour or size also changes between cells, this isn't pure rotation any more — it's a compound. Use R-1 for the turn, then look for the second rule.

Same as R-1, but the shape turns backwards. Rare, and used on harder items to catch solvers who default to clockwise.

The same L-shape, turning counter-clockwise — the arrows curl the other way.

Spot the signal

• The first cells seem to "retreat" — the shape turns in a way that feels backwards.
• Cell 2 confirms the direction, not cell 1 alone.

Name the rule

"The shape rotates by a fixed angle per cell, counter-clockwise."

Execute — Same as R-1, but the step is negative. If you measure cell 0 → cell 1 as +270° clockwise, it is more likely −90° (the shorter description usually wins).

Eliminate the traps

• Clockwise-predicted answer — the most common trap on a CCW item. Always confirm direction with three cells.
• Off-by-one — as in R-1.

Takeaway — If a clockwise step looks too big (270° or more), suspect counter-clockwise. Confirm with cell 2 before committing.

*How do you know not to use this tactic?* — If cells 1 and 2 both confirm a clean clockwise reading, it's clockwise. Don't reach for CCW just because the item looks hard.

Three variants where the simple "measure and project" model breaks: variable step, row-alternating direction, and whole-grid symmetry.

Left: a step that grows (+90°, then +180°). Right: whole-grid 2-fold symmetry — cells pair across the centre, not cell to cell.

Spot the signal

• The shape is the same in every cell (rotation confirmed).
• But measuring cell 0 → cell 1 → cell 2 doesn't give one clean step. The rule is hiding somewhere other than the per-cell step.

Name the rule

"The rotation rule is operating on something other than the per-cell step."

You have to find which thing.

Execute

1. 1Try R-1 first. Measure cell 0 → cell 1, then cell 1 → cell 2.
2. 2Row-alternating — if the step is equal within a row but row 1 reads in the opposite direction, project the missing cell using its own row's direction.
3. 3Variable step — if the step grows inside a row, work out how much it grows, then project the next step.
4. 4Whole-grid symmetry — if per-cell steps never confirm but cells pair up across the centre, stop reading in sequence. Find the missing cell's partner across the grid centre — cells (r, c) and (2−r, 2−c) — and rotate it.

Eliminate the traps

• Auto-pilot R-1 — "I assumed a fixed step." The most common trap on all three variants. Read the next row before projecting.
• Wrong direction on row-alternating — use the missing cell's own row's direction, not the grid's overall direction.
• Wrong pivot on whole-grid — the centre is the middle cell, not a corner.

Takeaway — When R-1 fails, the rule has moved up a level: to a meta-step, a per-row direction, or a whole-grid structure. Name which, then project.

*How do you know not to use this tactic? — If R-1 measured cleanly and held across the row break, the rule is a fixed step and you're done. Don't reach for R-3 because the item looks* hard.

Try it. 20 seconds. Apply R-1.

Answer & walkthrough

• Spot. The same F-shape sits in every cell. Only its angle changes — colour, size, and position all stay the same. One moving part: orientation.
• Name. The F rotates 90° clockwise each cell, in reading order — and the turn carries across the row breaks; it doesn't reset.
• Execute. Measure cell 1 → cell 2: a quarter-turn clockwise. Cell 2 → cell 3 confirms it. Because the turn carries across the rows, keep stepping — the missing cell is one more 90° clockwise turn on from cell 8.
• Eliminate. Each wrong option encodes a named mistake:

• Takeaway. Confirm the step with three cells, then carry it across the row breaks. The answer is just one more clockwise turn.

Apply R-1 — but watch the wrap. What happens to the angle after 270°? 30 seconds.

Answer & walkthrough

• Spot. The same F-shape sits in every cell; only its angle changes. Colour, size, and position all stay put. That's pure rotation.
• Name. The F turns 90° clockwise each cell, in reading order: 0° → 90° → 180° → 270°, then wraps back to 0°.
• Execute. Confirm the 90° step from the first two cells, then follow it across the grid. Cell 8 shows the F at 270°. One more clockwise quarter-turn brings it back to 0° — the upright F. So cell 9 is the plain, upright shape.
• Eliminate. Each wrong option encodes a named mistake:

• Takeaway. After 270° the cycle wraps to 0°. The trap is forgetting the wrap and turning one step too far.

Apply R-1 first. It explains the turn — but not everything. When one rule isn't enough, look for a second. 40 seconds.

Answer & walkthrough

• Spot. Same shape every cell, and it clearly turns — but the size also changes. Two rules are running at once.
• Name. Rule one: the figure turns 90° clockwise each step. Rule two: the size follows a Latin square — each row and each column shows all three sizes (small, medium, large) once.
• Execute. Project the rotation to the missing cell with R-1. Then read the size: its row and its column each already show two sizes, so the missing cell takes the third. The answer must match both the angle and the size.
• Eliminate. Each wrong option gets one rule right and the other wrong:

• Takeaway. When R-1 explains the turn but the cells still differ, a second rule is stacked on top. Solve the turn, then the size, and match both.
