Three Ways to Drill

Flash Card Drill

You're given a value — say, the Kings. Recall the first suit in the Mnemonica stack and the three distances between the cards. Enter your answer and get instant, detailed feedback.

Position Quiz

Given a value, enter all four absolute stack positions in any order. A step up from distance drilling — you know the stack cold when the raw numbers come fast.

Reference Table

The complete quartet distance table for all 13 values — first suit and the three jumps between them. Study it, verify your answers, or use it as a quick lookup while you're learning.

About Quartet Distances

In the Mnemonica stack by Juan Tamariz, the four cards of each value are scattered throughout the deck — but not randomly. For each value, there's a first suit and three consistent "jumps" to the next. These are the quartet distances.

Knowing them lets you locate any card in a quartet quickly: find the first, and you can calculate the rest. It's a powerful tool for memorized-deck work, and the kind of knowledge that separates fast, fluid performers from those still counting.

QuartetTrainer assumes you already know the Mnemonica stack. It's a drilling tool — not a substitute for learning the stack itself. If you're still working on Mnemonica, start with Mnemonica by Juan Tamariz, then come back.
