Now with color support! You move the dots around by tapping on the dot and then the empty square. If you line up 5 of the same kind, either vertically, horizontally, or diagonally, the dots disappear. The score doubles for every excessive dot in the line, that means double for 6 dots and quadruple for 7 dots. This is meant to be a pastime more than a challenging game, although you can try to make it more difficult by scoring 9 dots at a time, frequently. Please purchase if you still like it after 7 days of use.
