32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Missing piece fill
- In pattern completion, the fill of the missing square must match the fill of the region it touches: solid, striped, or outlined.
- Boundary continuity
- A missing piece at the edge of a design must continue the boundary line without a bend, gap, or change in curvature.
- Side count test
- Count the sides of the piece bordering the hole; an answer whose sides do not match the opening cannot fit.
- Mirror symmetry rule
- If the whole design is symmetric about an axis, the missing piece is the mirror image of the piece across that axis.
- Stripe angle match
- Diagonal stripes in the surrounding region fix the angle and spacing that the missing piece's stripes must follow.
- No internal overlap
- A candidate piece is wrong if it draws a line through the interior of the existing design, even when its outer edge fits.
- Grid motif translation
- When a motif repeats on a grid, the missing cell holds the same motif moved, not turned, unless the grid shows rotation.
- Shape versus fill tiebreak
- When two answers share a shape, choose by fill; when they share a fill, choose by shape.
- Analogy reading order
- Analogy items read A is to B as C is to blank; the rule that turns A into B is applied unchanged to C.
- Add or remove part
- A frequent analogy rule adds an inner shape in the second figure or removes one, and the same addition applies to the third figure.
- Fill change rule
- If A is solid and B is outlined, then C's fill must change in the same direction to produce the answer.
- Size change direction
- If A grows into B, the answer must grow from C by the same amount; a shrinking answer breaks the rule.
- Inside-outside shift
- A position rule moving a shape from inside to outside in the first pair moves the third figure's shape outside as well.
- Two-feature pairs
- When A and B differ by two features, the correct answer differs from C by exactly those two features and no others.
- Wrong-attribute trap
- An answer that changes shape when the pair only changed fill is wrong, because the rule was applied to the wrong attribute.
- Quarter-turn check
- Rotation is uncommon at this level; when it appears it is a quarter turn, so confirm the orientation of pointed shapes.
- Constant step rule
- In a serial sequence, the visible frames advance by a fixed step, and the blank continues that same step.
- Count series
- A count series changes the number of a repeated element by a fixed amount, such as one, two, three, four.
- Alternating series
- Alternating series apply one rule on odd positions and a different rule on even positions; identify the blank's parity first.
- Rotation series
- A rotation series turns the shape by the same angle each frame; track one landmark corner to find the blank's orientation.
- Position series
- A position series moves a shape one cell per frame along a row, column, or diagonal, and the blank continues that displacement.
- Fill cycle
- A fill cycle repeats a fixed order such as solid, striped, outlined; the blank takes the next fill in that cycle.
- Dual-rule sequences
- Some sequences run two rules at once, such as growing shape plus cycling fill; the answer must satisfy both.
- Apparent reversal
- A sequence that seems to reverse direction usually follows a reflection rule, so check whether the shape is mirrored rather than moved.
- Left-right flip
- A left-right flip mirrors a figure across a vertical axis: left and right swap while top and bottom stay in place.
- Clockwise quarter turn
- A quarter turn clockwise moves a feature at the top of a figure to its right side.
- Counterclockwise quarter turn
- A quarter turn counterclockwise moves a feature at the top of a figure to its left side.
- Fold and punch
- Folding paper and punching a hole yields holes mirrored across the fold line, doubling the count unless the hole lies on the fold.
- Shape overlay union
- Combining two shapes overlays their outlines, and the answer shows the union with no part of either shape removed.
- Transparent overlap
- When a transparent shape covers another, overlapping regions may change fill, so trace each region separately.
- 180 degrees versus flip
- A half turn equals a flip only for symmetric shapes; for asymmetric shapes the two produce different pictures.
- Reverse the operation
- Check an answer by mentally unfolding or un-rotating it; the result must return the original figure.
