MEMORY MATCH
The Memory Match Blog
The Memory Match Blog covers two sides of the same deck: the math and habits that clear a board in the fewest possible moves, and the tiny shuffle algorithm that quietly guarantees every layout you're dealt is perfectly fair.
How Few Moves Can Win a Memory Game?
The one-unknown rule, what optimal play actually looks like, and realistic move-count targets for every grid from 2×3 to 6×6.
Read Inside the GameInside the Shuffle: Fisher–Yates and the Fair Deal
Why naive shuffles are subtly biased, how the 1938 Fisher–Yates method fixes it in a few lines of code, and what "every layout equally likely" really means.
ReadBoth posts grew out of the same Memory Match game on this site, so the numbers in them aren't theoretical — they describe exactly how the deck you play against is built and how a careful player actually beats it. The strategy post breaks down the "one unknown card" rule that turns a game of luck into a game of tracked information, with move-count targets you can check your own scores against on every grid from the smallest 2×3 board up to the full 6×6. The shuffle post goes one level deeper, into the Fisher–Yates algorithm itself: why the more obvious ways of shuffling an array quietly favor some layouts over others, and why the fix has stayed the standard method since 1938. Together the two posts cover the full lifecycle of a single game: how the deck in front of you was assembled, and how to make the best possible use of the information it gives up one flip at a time.
