Frequently Asked Questions
What is QuartetTrainer?
QuartetTrainer is a drilling tool for magicians who want to memorize the quartet distances in the Mnemonica stack by Juan Tamariz. It offers three practice modes: Flash Card Drill, Position Quiz, and Reference Table.
Do I need to know the Mnemonica stack to use this app?
Yes. QuartetTrainer is a supplemental training tool — it assumes you already know the Mnemonica stack. It does not teach the stack itself. If you're still working on Mnemonica, start with the book by Juan Tamariz first, then come back.
What are quartet distances?
In the Mnemonica stack, the four cards of each value (e.g., all four Kings) are distributed throughout the deck. For each value, there is a first suit and three consistent "jumps" — distances — to the next card of that value. Knowing these lets you locate any card in a quartet quickly during a performance.
How does the Flash Card Drill work?
You're shown a value — for example, "Find the Jacks." You select the first suit (the suit of the first Jack in the stack) and enter the three distances to the remaining Jacks. Tap Check to see your result, with a full breakdown of the correct positions and distances.
How does the Position Quiz work?
You're given a value and asked to enter all four absolute stack positions of those cards, in any order. This tests deeper recall than the distance drill — you know the material cold when the raw numbers come without calculation.
What is the Reference Table?
A complete lookup table showing the first suit and three distances for all 13 values. Use it to study, double-check your answers, or verify as you're learning the distances for the first time.
Does the app collect any personal data?
No accounts, no tracking, no ads. See the Privacy Policy for full details.
