4 stars: This game is very addictive.... I do have a suggestion. Was the levels go up maybe you could make it alittle more challenging by making one of the tubes color coded. The blue has to go in the blue tube. Could make it more challenging to play.
3 stars: Fun game but ads every 2 or 3 games gets really annoying. Will probably uninstall it. It's a shame. Still like the game but now the ads are coming in the middle of a game and every game and a half. Uninstalling it now. Really too bad.
3 stars: The game was diverting enough to start, but lately they're getting more greedy with ads, so you end up getting multiple ads on one level. It used to just be one at the end of the level, which was fine. If it was still like that, I would've given a 4 star.
4 stars: Great time waster. I have gotten to the point they are all the same over and over. Would love for there to be bigger and bigger fields.
4 stars: I was enjoying it but as they started to add more colors, I was finding it hard to play. Not because the game itself was getting too hard, but because I am color blind, I was having trouble differentiating some of the colors.
3 stars: This would be a 5 star if it weren't for the advertisements that happen in THE MIDDLE of the level. It would be fine if they were after you completed the level, but it is so frustrating to be mid-click and you get a 30 second ad.
5 stars: Love this game. It's challenging and addicting...good for concentration! Works well.
