Flow Free Online

At first glance, this free online game doesn't seem that difficult: all you have to do is connect dots of different colors with your partners. But the hard part starts a bit later, in the next few levels, where there is too much free space with too few points. Even if you connect all the dots with lines but the playground is not 100% full, the game will not consider a level to be over. So if, after all, you think it's a complicated game, it is. The game records the number of moves you make; obviously, the less you do, the better it is for the score. If you don't like your current efforts, there's always a way to reset the level or undo your moves to make them more correct.
