Additap – Summing Tap Game ($0.99) by myice92 is a math game requiring addition to be done quickly in your head within a time limit. The math problems range from being very easy to extremely challenging.
In the center of the screen is a square with a large number showing a rapid countdown of your remaining time. There are also some smaller numbers bouncing around. It’s the smaller numbers that your eyes will be chasing after.
You have got to add together those smaller numbers as fast as you can. At the bottom is a rectangle with three stationary numbers. Once you‘ve added together the moving numbers, select the correct answer from the bottom row.
There are six modes of play that vary the speed of the numbers, how many numbers you get, and how much time you have to do your addition. The various modes allow the game to be played by people of varying skill levels.
Additap is not the most fun app you’ll ever play since it does get a bit repetitive. It would be nice to have some other math operations to choose from. However, for puzzle enthusiasts with some time to kill, it will do nicely.
