| Each of the twelve Cards shown fully encloses a Number of rhombi, from one to four. A Set consists of three separate cards (no corners in common) for which the numbers are sequential; i.e. either 1, 2, 3 or 2, 3, 4. |
Click on the Boxes below three cards to choose your set.
The object of the game is to identify six such sets of three cards. (You may also find two sets whose numbers are equal, but they don't count.)
