Play begins by passing out 5 cards to each of the
players and placing the remainder of the cards face
down in a pile in the middle.
Next, players must remove any matches that they
already have in their hand.
The first person then asks any of the players if they
have a certain card. Players can ask for a specific
product or ask for the two factors card. If the first
person makes a match they continue their turn. If the
person does not have the card requested then the
player must draw a card from the middle. If a match is
then created the player may lay it down, but their turn is
over.
Play continues until all of the possible matches have
been created.
The player with the most matches is the winner
