Learn the 3-Step Method
1Compare same-first-letter figures.
AX and AY are both triangles → the first letter codes SHAPE (A = triangle).
2Compare same-second-letter figures.
AX and BX are both white → the second letter codes SHADING (X = white).
3Code the mystery figure.
A black square: square → B, black → Y → code BY.
Worked Example
Given the codes above, what is the code for this figure?
Watch Out! Common Mistakes
Derive, don’t guess! In another question A might mean shading. Only the example figures define the letters — read them every time.
Both dials! Confirm the second letter with its own comparison pair — half-cracked codes produce confident wrong answers.
Harder papers add one! Three-letter codes add a dial (often size or rotation). Same method: compare figures sharing each position.
⬇ Cheat Sheet
- Compare figures sharing the first letter → its dial.
- Compare figures sharing the second letter → its dial.
- Derive every letter from the examples given.
- Apply the cracked code to the new figure.

Quick summary
- Each letter position controls one property dial.
- Figures sharing a letter share that letter's property — compare to derive it.
- Never assume meanings; the examples define the code fresh each question.
- Apply the cracked code dial by dial to the new figure.
Frequently asked questions
How do shape code questions work?
Example figures come with letter codes; each letter position encodes one property (shape, shading, size). Comparing figures that share a letter reveals its meaning.
What's the safest cracking method?
Pair up figures sharing the first letter and note what else they share — that's the first dial. Repeat for each letter position independently.
Do codes ever have three letters?
Yes, on harder papers — a third dial like size or rotation joins. The comparison method scales: crack each position with its own pair.
