Rhombus begins with a large empty table space surrounded by 2 to 4 players, and each player holds a hand of three Rhombus cards printed with geometric shapes in several colors. Players use these cards to form diamond shapes (rhombuses) in different sizes and color combinations to score points. It's possible to form multiple rhombuses with a single card placement. The colorful array of cards grows to cover the table until the last card is placed and final score tallied. Fast fun for for ages 10+. Made in the USA.
