## What is QuartetTrainer?

QuartetTrainer drills you on the starting suit and distance numbers for every four-of-a-kind in Juan Tamariz's Mnemonica stack — the quartet distances concept discussed in Pit Hartling's In Order to Amaze book.

Once you have these distances memorized, you can cut to any four Aces, Kings, or any other value instantly during a performance. QuartetTrainer builds that recall through three focused training modes.

FLASH CARD DRILL
All 13 values are presented in a shuffled session. Select the first suit, enter the three distances, and tap Check. You get instant feedback showing exactly which answers were right or wrong, plus a full position breakdown for every card in the quartet.

POSITION QUIZ
Enter all four stack positions for each value in any order. This mode builds a different kind of recall — working directly with positions rather than distances, so you know the stack cold from every angle.

TIMED CHALLENGE
Race through all 13 values as fast as you can. The timer starts the moment you tap Start and runs until you correctly answer every value. Wrong answers must be corrected before you can advance — the timer keeps running. Your best time is saved and displayed every time you open the challenge.

REFERENCE TABLE
A clean, always-available table of all 13 quartet distances for quick study between sessions.

Built for magicians who work with the Mnemonica stack and want to perform the quartet control with speed and confidence.
