INSIDE THE COLLECTION
The useful part is the why.
Eight ready-to-print PDFs
English, Spanish, Brazilian Portuguese and French, each in A4 and US Letter. Each full file is 24 pages; all contain the same 24 exercises.
More than an answer key
Each solution explains the rule or deduction. Questions, hints and answers occupy separate pages so you can decide when to peek.
Two hints, one at a time
Try a small nudge before reading the solution. There is no timer, account, or score you have to unlock.
An activity for your group
Includes a 20-minute activity guide for 2–4 adults. The purchaser may print copies for personal use and their own internal classes or group sessions.
BEFORE YOU CHOOSE
A few practical details.
How will I get the files?
One-time purchase on itch.io. Download the PDFs after payment; final taxes and available payment methods appear at checkout.
Do I need special software?
A PDF reader is enough. Choose A4 or US Letter to match your paper and print at 100% / actual size. The question pages use white backgrounds and work in grayscale; you can skip the illustrated cover.
Is this an IQ test?
It is reasoning practice for adults, for education and entertainment. It has no population norms and provides no standardized IQ, diagnosis or certification. Difficulty labels are editorial estimates.
Can I resell or upload the files?
No. The license permits personal use and printing for your own internal class or group sessions. It excludes resale, public uploads, redistribution of the full collection, and clinical or hiring assessments.
Was generative AI used?
Yes, for writing assistance and cover artwork. Puzzle diagrams are precise rule-based vectors. Answers were checked with calculations and finite-model verification. Four real samples let you judge the collection before buying.
