Memory Match: replay one layout and account for every turn.
Retry a fixed board, compare checked ten-turn and nine-turn routes, and separate completed turns, reveals, and button presses.
A smaller turn count is easier to interpret when the card positions stay the same. Otherwise, a new shuffle changes what you encounter as well as how you play. This lesson provides one fixed Memory Match board, two complete routes through it, and a ledger that explains their ten-turn and nine-turn finishes.
Use it to check how the controls and counter behave. The printed layout gives away every pair, so this is a replay exercise, not a blind memory test or proof that a method improves your ability.
Load a board you can repeat
Choose Practice this example in the side panel, or Load turn-ledger example below the Memory Match board. Loading replaces the current board, hides all sixteen cards, clears collected pairs, and sets Turns to zero. Rows A–D run from top to bottom; columns 1–4 run from left to right.

The diagram is the answer map. The live practice begins with question marks, not these symbols showing. The two diamonds are A1 and C4; the circles are A2 and C1. Other pairs are A3/C2, A4/C3, B1/D4, B2/D1, B3/D2, and B4/D3. Each position contains one card and each symbol appears twice.
Retry this board hides the same cards and resets the attempt. It also works on an ordinary shuffled board. New puzzle generates a fresh shuffle instead. A practice entry reloads the fixed example when refreshed; this does not save your previous attempt.
Count a turn only after the second different card
Select A1, the diamond. Turns still reads 0: a first reveal is not a completed turn. Selecting A1 again does not count as a second card. Now select A2, the circle. Turns becomes 1, the symbols differ, and both remain visible.
While that mismatch is open, a third card cannot be revealed. Choose Hide pair and continue when you have read the two locations. It hides those cards without adding a turn. Keyboard focus returns to the second card. The board has not moved or reshuffled.
There are three different things to count: completed two-card turns, successful pairs, and individual reveals. The game displays Turns. A reveal count in your own ledger counts a card each time it changes from face down to face up, including a card seen on an earlier turn. It is not a count of every mouse click, key press, or card that remains visibly matched.
Replay a ten-turn route
Return to the exact start with Retry this board. Follow the two coordinates in each row, in order. After rows 1 and 2, use Hide pair and continue before starting the next row. Both are mismatches; the second deliberately repeats information you already have. Matching rows need no hide action.
| Turn | Cards | Outcome; pairs found |
|---|---|---|
| 1 | A1 + A2 | Mismatch; 0 pairs |
| 2 | A1 + A2 | Mismatch; 0 pairs |
| 3 | C1 + A2 | Circle; 1 pair |
| 4 | C4 + A1 | Diamond; 2 pairs |
| 5 | A3 + C2 | Triangle; 3 pairs |
| 6 | A4 + C3 | Square; 4 pairs |
| 7 | B1 + D4 | Star; 5 pairs |
| 8 | B2 + D1 | Plus; 6 pairs |
| 9 | B3 + D2 | Sun; 7 pairs |
| 10 | B4 + D3 | Heart; 8 pairs |
After turn 4, two pairs have been collected, but the counter reads four because two earlier turns failed to match. After turn 10, all eight pairs are face up and the game reports completion in ten turns. Retry is available even after completion, with keyboard focus moved to that button.
Account for the total before comparing it
Every completed turn in this game does exactly one of two things: collect one new pair or produce one mismatch. Matched cards cannot be selected again. Therefore, at any point, completed turns equal pairs collected plus mismatching turns.
Turns = collected pairs
+ mismatches
Finished board:
Turns = 8 + mismatches
Route A has eight matching turns and two mismatches: 8 + 2 = 10. Its twenty individual reveals include the same A1 and A2 cards being turned up more than once. Hiding the two mismatches adds two control actions, but no further turns or reveals.
Eight is the smallest possible completed turn count for this sixteen-card game: each of eight pairs requires a separate two-card turn. A route with no mismatches reaches that count if all partners are known or guessed correctly. Eight is not a target that a new player must reach, and a lucky eight-turn shuffle would not establish better memory.
Retry and remove just the repeated mismatch
Choose Retry this board. Follow row 1 of Route A, hide the mismatch, and then go directly to row 3. Continue through rows 4–10 as printed. These are the same card positions and the same eight successful pairs; you have removed only the deliberately repeated mismatch.
This is Route B. Its first turn is A1/A2; its second is C1/A2, which collects the circle pair. Its final heart match is turn 9, not turn 10. It has eight matching turns, one mismatch, and eighteen individual reveals. Saving one failed two-card turn saves two reveals.
The result is a checked comparison between two specified routes. It does not prove that you would discover those eight partners on an unfamiliar board. The full map is supplied here, and a retry does not erase what you remember. Use the example to identify unnecessary repeated work, not to label every genuine first-time mismatch as a mistake.
Three ledger checks
You have collected three pairs and made two mismatches. What should Turns show?
Five: three successful turns plus two unsuccessful turns. The six matched cards are not six turns. If you have just revealed the next first card, Turns is still five until you choose a different second card.
You finish in eleven turns. How many mismatches were there?
Three, because 11 − 8 = 3. There were twenty-two individual reveals across those eleven completed turns. This calculation assumes the standard sixteen-card board and a single uninterrupted attempt.
You press Hide pair and continue after a mismatch. Does that make the turn count one larger?
No. The second reveal already completed that turn. Hiding only makes the unmatched cards available for another turn. Retry, by contrast, starts the counter and collected pairs over at zero.
Use the reset that fits your question
For checking a route, keep the positions with Retry. For an unfamiliar layout, choose New puzzle. For revisiting this printed example later, use its practice entry. If you compare attempts, record whether the layout was already known, which pairs were remembered, and how many mismatches were repeats of known information.
Do not compare an open-map replay directly with a blind shuffled round as though they measured the same task. This lesson checks accounting and control behavior under this site's rules. It does not rank players, prescribe a universal strategy, or make a health claim. Boards and moves remain in the current tab; they are not saved or submitted.
