Concentration is the ultimate party game where players take turns listing anything from names of things, places and many others that fall under the category of the card picked, starting from the player that picks the card.

Game is played in the counterclockwise direction and whoever hesitates or repeats words used by any other player in that round is eliminated from the game or serves an agreed penalty (e.g., drinking a beverage or paying a fine). The next player after the eliminated player continues the game by picking the next card and starts listing things that fall under category of card picked, and the game continues in the counterclockwise direction. There are 10 blank cards in the deck. Whoever picks a blank card gets to pick a topic and all players list items that fall under that category.
