Vier aug einen streich combines elements from the card game Memory and the chip game Connect Four.
The game consists of a deck of 16 cards with various simple images, 16 chips with corresponding images, a bag and a rule sheet.
The cards are placed face-down on a table in a 4x4 grid and the chips are placed in the bag. Players take turns drawing chips out of the bag and attempt to turn over the card with the same image as indicated on the chip. If the image on the card does not match the image on the chip, the card is flipped back over and the chip is returned to the bag. If the images match, the chip is placed on the card.
The winner is the person who places the chip on a card that creates a row horizontally, vertically or diagonally of 4 consecutive cards with chips on them.
