Super Corners is an addicting game of strategy, adding numbers so that the total is a multiple of 5 while matching colors. Variations are also available for multiplies of 4 and multiples of 3. Fifty cards are in each game and final scores are stored. When two cards form a “corner", each touching numbers must match colors and add up to the multiple and the scores are multiplied by two. When three cards create a “bay" and a card is placed, the total of the three pairs is multiplied by three. Four cards create a “window" and the total of the four pairs is multiplied by four.
