It is common that the child will make significant progress by developing memory strategies. Memory and childrenĬhildren should periodically return to this memory until they are easily capable of solving at least the most basic levels. When you find a pair they are removed from the board and when you find all the pairs in this memory, you have completed the level. Try to remember these images as it becomes easier to find pairs the longer you play.

If you can't find a pair, the flipped cards will be flipped back with the face down. Then try to find another card that has the same image as the first.

On the game board, there are always two identical images. The higher the number, the more cards are in the memo game. This leaves two spaces for the two C cards, and so only one way to place them, giving $5 imes 3 imes 1 = 15$ possibilities.Test your memory with this memory game. Then the first B must go in the first available slot, leaving three options for the second B. The first card must be A again, and there are five remaining choices for the second A. With $n = 3$, there are 15 possible sequences.

The chance that of getting a match on your first turn is $rac$. In which case, on your second turn you pick a new card, which must be either A or B, allowing you to get a match, so the game take three turns. Alternatively you pick A then B on your first turn. Either you get a match on your first turn, in which case you also get a match on your second turn and the game is over in two turns. With $n = 2$, there are two options for what can happen. You will win in one turn no matter regardless of your strategy.

Starting back at $n = 1$, the game is, again, trivial. Do this for both cards you pick on your turn. Now you have to have a strategy, but the perfect strategy is quite straightforward: if you can make a pair, then make a pair, otherwise turn over a card you haven't previously seen. Going, from one extreme to the other, what if you have perfect memory (or if you just don't turn the cards back over).
