The Knapsack Puzzle Game

A game of filling a one-dimensional box full of blocks (representing any stuff like packs of yummy food).

The operations are really easy and intuitive using iPhone touch screen. Just drag and drop the blocks in to and out of the box below.  The strategy, however, may not be simple. Especially in Hard mode, you need some observation, planning and trying. So you get visual training as well :)
