Flow

This is a great little game, very simple and sometimes multiple ways to solve the puzzle and sometimes there is only one way to solve the puzzle. Try it!! The free version has plenty to offer before you have to buy an up-grade pack. It is great tool to help kids learn problem solving skills and in order to earn a perfect score all the boxes in the grid must be filled and dots connected using the least number moves.


You can free play or see how many solve in the "time trials." The 5 X 5 are the easiest progress through to 9 X 9, which are harder.
