Double Nines Player 1 keeps the calculator. Player 1 enters a 2-digit number less than 99. Player 2 tells Player 1 to add a number. Player 1 then tells Player 2 the number of nine's in the sum and one other number. Repeat this until 99 is shown on the calculator. The objective is to get 99 on the display with as few turns as possible. If the sum goes over 99, subtract the number just added – no new information is given.
