This game is amazing! The concepts behind it are ingenious, and it is totally designed to help you think quickly, sharply, critically, and strategically. You get faster and faster, and trying to beat the records is very exhilarating! I love it, and am disappointed as to how few people know about it. I am going to do my best to increase it's publicity, and really get it out there.

I enjoyed the game. Wish I could give 4.5 rating. The concept is like picross puzzle but modified version, which was fine for me. The difficulties can be harder than what is given in the app. You can go through the app pretty quick. But it was fun while I was playing and was a nice time filler.

It's a great app if you have perfect vision and small fingers. The dotted lines are way to feint so it's hard to tell what you are supposed to be joining up and the colour selection doesn't like people with big fingers. If this is resolved next update I will happily change my review to a 5 Ed

Eta: Played the entire game twice now. Enjoyed each time. ///Great game! If you like sudoku, you MUST try this cool game! Finished it so uninstalling. Please release more games like this!

Love this game. Up until I ran out of levels to play 😟. The invite friends on FB levels won't work. It says it doesn't support FB. So please bring us some new levels!!

Nice game. I noticed one little bug: I completed Valentine's Day with all stars and cups but I don't get the cup for the entire pack. On a phone the controls can be a bit annoying when lines and nodes are almost too close to draw the right line.

Fun game. Only reason I didn't give it a 5 is that there aren't enough advanced puzzles and they could be higher in difficulty. After purchasing pack 1, there were a couple of harder puzzles, but not many. The harder puzzles need brighter lines showing the connection. I dropped my game play rating from 4 to 3 for this issue.

I absolutely love this game. Its simple in concept but gets you thinking. The best part is that there are so many different levels to keep you playing for a long time.

I love it so much, I paid for ads to be removed! Easy to see, easy to play, gets progressively harder. Fun!

great overall game but the mascot (if if you can call it that) is not to my particular liking and inability to pinch-zoom or change color while selecting edge makes it 4 star instead of 5.

It's a decent puzzle. The only problem is that each level seems to be the same type of thing, over and over.

Awesome game. Interesting and fun. Makes you think just a little. However your English Grammer needs work. And the world records seem a little impossible Needs more levels. While there are lots of levels they are all too easy. Finished all free levels in 2 days. Now half way through pack 1 . Can't find any other game even close to this. So please release lots more levels often. NEED REFUND. thought I was buying a new pack. Paid $2.22 for what I thought we 44 new levels and 10 hints. Come to find out I had already bought the same 44 levels. Pretty tricky there. So please refund my money. Thank you.

Fascinating game, tests logical thinking sometimes more than I want. Impossible to see the interior lines in some sets on Droid Turbo II

If there's a good side to one's phone turning into a brick, it's rediscovering gems like this when deciding what to load on the new phone.

Pretty f'ng fun. A couple puzzles are a little too intricate so it's hard to see where your line Starts & Stops. Nothing so bad you can't work through it though.

Very fun and hard to put down, but some gameplay issues. Some levels the hardest part is figuring out which numbers belong with each corner. Also some tiny & closely spaced lines are hard to do correctly, even zoomed in; and colored lines are wider than uncolored lines, and sometimes obscure the numbers, again even zoomed in.

Really good time waster for breaks or bus trips.... It's like a colors version of sudoku, same kind of puzzle solving.

Two stars less because colors are indistinguishable, and there is no color-blind mode. Read about accessibility.

It's a unique logic game. I enjoy it for the most part. However, the colors and size of the board make it difficult to see. Try making the board bigger and switch out the pastel colors with something brighter. Some people might also enjoy a white background, so make that an option. Also, the music is so bad, I had to switch it off.

Very nice puzzles although sometimes annoyingly small on the screen making it hard to be precise. Especially in the smaller packs.

This is a great puzzle game but it gets only one star for locking certain levels behind Facebook. Granted, it's only twelve levels and I'm probably being petty but I'd rather pay for level packs than be forced to share through Facebook in order to unlock them.
