The CLINT Files — Complete Collection
Twenty case files, four series and two hundred challenges. Each workbook is self-contained and designed as a file to work through: evidence or information to analyse, ten challenges scored out of 100, a final report and detailed answer keys.
Series 1 — Investigations: Cold Case, Secret Code, The Alibi, The Tail, False Witness — deduction, encryption, chronology, visual attention and critical thinking.
Series 2 — Pure Logic: Grids, Sequences, Volumes, Bets and Probabilities, Logic Traps — Sudoku and Kakuro, inductive reasoning, mental rotation, probability and cognitive biases.
Series 3 — Words & Knowledge: Expert Vocabulary, Origins, General Knowledge, Atlas, Screens and Sounds — language, etymology, knowledge, geography, cinema and music.
Series 4 — Performance: Speed, Memory Span, Switch, Mental Math, Stamina — timed exercises that can be repeated to track progress.
A tracking page appears at the end of each file so scores can be recorded and progress followed from one series to the next.
Format: 20 high-definition A4 PDF files, 429 pages in total, ready to print at home. 100% digital product — all download links are available immediately after purchase.
Twenty cases to crack,
and a mind that gets back to work.
Five investigations and fifteen cognitive missions, printed at home. Every file has its evidence, its ten scored challenges, its final report — and answer keys that explain the reasoning instead of simply handing over the solution.
Why take the whole collection
Every file stands on its own, but they don't work the same muscles. The investigations call on deduction and chronology; pure logic, on grids and sequences; words and knowledge, on semantic memory; performance, on speed and sustained attention.
Taken one at a time, each case is a good evening. Taken together, the collection becomes a programme: the logbook at the back of every file is there to collect all twenty scores and show, series by series, where you are comfortable and where you are not.
A real thread running through
The challenges are not stacked side by side: they all draw on the same evidence, and the last one closes the case.
A score at the end of every file
Within one file: ten challenges, 100 points in total. You add them up, read your rank, and carry the result over to the logbook, which holds all twenty scores of the collection.
Puzzles that actually work
Every grid has exactly one solution, reachable by pure deduction. The ciphers are computed, not copied.
The twenty files
Five narrative investigations and fifteen cognitive missions, split into four series. Every file stands alone: if only the investigations appeal to you, start with series 1. Click a file to open it in a new tab.
