Fill Dots

Fill Dots is a simple puzzle that requires you to fill a grid of dots with blue color. There is a grid (5x5) of dots, of which some are filled(blue) and some empty(white). When you tap any of the dots, that corresponding dot, along with the four surrounding dots toggle their state, ie filled dots become empty and empty dots get filled. So you have to plan and tap the dots such that they all become blue. There are five levels(main) and each has five sub levels, labelled 0.1, 0.2, 0.3... etc. They are arranged in the order of complexity. The first four levels (0-3) follow similar rules, but the five sub-levels in level 4 are special, as some dots automatically toggle in between the game, making it really tough. Your score will depend on the number of extra taps you use(based on certain parameters) to solve a particular game, along with the time taken. The score is out of 1000.
