You are a military man who was sent on an assignment to investigate in a dark forest due to the frequent disappearance of people. After spending a little time, you realize that ancient prisoners are being revived in this forest, and the longer you are in it, the more and more of them.
In front of you are cards with different "delicious" images. The images are hidden from you. You need to find all pairs of identical images. You can open two cards at the same time. Remember the pictures, look for their pairs, and try to use as few attempts as possible.
Sometimes it's better not to wait until the sun goes down. Having decided to spend the night in an abandoned village, you could not even imagine that the rumors about the living dead would turn out to be true. You will not see the dawn, but will you be able to sell your life more dearly?
