Each player in Sideboards creates an eight-card sideboard, then sees how they fare against everyone else.
In more detail, the deck contains sideboard cards that each feature five differently-colored drawers on top of one another, with drawer handles of three types. On a turn, everyone plays simultaneously, choosing and playing a card from their hand, passing their remaining cards clockwise, then drawing a new card. After everyone has played eight cards, you tally your score.
What are you scoring? Three task cards are in play each game from a deck of thirty. One task challenges you to arrange drawer colors in a particular pattern. Another forces you to consider the arrangement and type of handles. The third lets you score for creating rows of color or handles.
Sideboards includes a solo mode in which you compete against yourself for a high score.
