iNum Lite app for iPhone and iPad

iNum is a mental calculation game (like the sudoku game) which stimulates the left hemisphere of your brain dedicated to numerical computation. In a fun way, you will develop your sense of the relationship between numbers and learn how to calculate faster!

Instructions:
iNum is played with a grid of 16 numbers, which are generated randomly. You have 60 seconds to find combinations of numbers from the grid that add up to the total specified below the grid. You need to find four combinations to advance to the next level. Select a number by pushing it and you can deselect the same number by pressing it again.
