Open Middle®
Directions: Using the digits 1 to 7, at most one time each, place a digit in each circle so that the sum of the numbers in 3 squares (the middle horizontal line or 2 diagonals) are same.
e.g A+B+C or D+B+E or F+B+G
Is there more than one solution?
Hint
Be strategic to think about the number in the center circle.
