The classic calculator game comes to the cell phone! Select numbers one at a time. In the Standard game, if the numbers selected add up to 10 they are removed. If the numbers fill the box you lose. One point is scored for each number removed. Bonuses are awarded for clearing the box. In the Advanced game, each time you remove numbers the goal needed to remove numbers changes. The Subtotal displays the total of the numbers currently selected. The longer you play, the faster new numbers appear. Additional options (Slow, Fast, Fastest) determine the initial speed at which numbers are added. Is it too hard for you?
