Add 'em - Timed

This addictive little game asks a seemingly simple question: how fast can you add?

The objective of the game is to add numbers to equal the number shown on the top right of the screen. You select numbers by tapping on them until total equals the number in question. You need to be fast, and reach the total before time runs out (shown by slider on top). You get more points by selecting more numbers, and you start earning more points as you move up the levels.

The timer is what complicates matters. As soon as you've reached one number, another appears ... and another … and another. You're not going to quit now, are you?
