(Updated 11/12/19) New facelift looks fresh, but I'm not paying a dollar a day for new puzzles, sorry. (Original review) While not the most challenging of puzzle games out there, this is an interesting take on the picross-style puzzle, and it's very satisfying to work out the correct order in which to mark red and white segments in order to solve each puzzle. Done by the same developer as another of my favorites, Battleship Solitaire. Highly recommended!

Was one of my favorite games, until they went to subscription pricing & for way too much a month for the amount of puzzles you get in that time frame. I've been playing on Play Pass & it still says it's part of play pass with "No ads or in-app purchases with your Play Pass subscription", however, it's not allowing play & everything is locked unless you subscribe. I'm gonna hate to lose it, but not subscribing. There's not enough 13x & 14x puzzles anymore anyway.

Thanks for your review. The game is still available in the play pass (I'm not sure to understand if that's your problem). Without play pass, you still have free levels everyday as well. Also, the new version has more free levels than the one of a few years back. I'm really sorry to see you go.

This is an amazing game. As close to pure logic as it gets. The thermometer concept really helps explain the mechanics very well, making them rather intuitive. My only complaint is that thirty boards for the dailies is a bit much.ten would be much more doable, but that in absolutely no way detracts from the over all experience. It's one of the best puzzle games I've ever played.
