A free program for Android, by AK Crossword Puzzle.

In Link-a-Pix, you are given a number and a picture, and you have to connect them by drawing a line between them. You can only connect two numbers at a time, so you have to think a little bit to solve the puzzle. You have to be careful not to cross the lines, because that would cause you to lose points. If you get too many points, you will lose the game.

There is also a special mode for children, where they can play with their parents or other kids. The kids can get a lot of fun out of it, because it is very easy to play and the rules are very simple.
