I love, love, love this game! I finally have gold trophies on all 250 levels, although it took me a few months of playing sporadically to get there. Will there ever be more levels? All I can do now is replay levels and try the daily challenges.
A trick to keep in mind is that mathematically, sometimes the puzzles are impossible to win. When this happens, back out of the puzzle, and press play again. Voila, the puzzle resets!
This game is fast, challenging, and mathematical, but not in a classroom way. There are angles in some of the geometric shapes that help you figure out where to place your points; in other puzzles, its not obvious at all. The best piece of advice I got while playing this game was from my son: he said that "they (the opposing dots) are going to get some portion of the puzzle; you just have to try to get more of it." It seems simplistic, but I had a mindset (at first) that I didnt want to give away any more than I had to. Accepting that they will get some of the space made it easier, somehow. Hope that makes sense.
Great game and I highly recommend it!
