A company of witches gathered in the house of one of them decided to pass the time playing a card game Hyper Scary Halloween Party. You take part in this entertainment. Before you will see the cards lying on the playing field. In one move, you can flip and consider two of them. Try to remember the images that are printed on them. As soon as you find pictures of two identical objects or creatures, click on these cards and flip them at the same time. Thus, you remove the card data from the field and get points for it.
