Three numbers game

Start with 49 counters, or m&m's ...[br][br]Find three numbers that whose squares are joined by side or by corner that make the target number shown in blue (using any arithmetic operations).[br][br]The first to find the blue number takes the m&m. [br][br]Click the blue target number to change it.[br][br]When you see your first number again, you should have no m&m's left. [br][br]New board also shuffles the target cards.
