Fun but not worth it

Even with reading the reviews it still seamed like a fun thing but I dont know if its worth 2 dollars. With only two game types
:blitz which is get to 15 in under ten seconds
:zen which is get to 15 fast as possible.
Would be better if the numbers you clicked would be replaced by bigger numbers and the point was to get as high as you can in 60 seconds.
Doesnt have any challenge and doesnt feel like it is training my brain.
Still shows promise with so many different update possibilities like levels with increased difficulty and other game types.
In the end glad I had a gift card to buy it.
