Ratings and reviews

Fantastic selections of puzzles, though my one and only concern, which is really only a nitpick, relates to the Filling puzzle. I'm not too big a fan of the fact that fields of 2 or 1 can exist but not entirely be that apparent, ie, a 4 could finish out a corner or it could go out into who knows where in the open field, or it could just be a 1 that decided to want to exist in the corner. If maybe there were a way that 1 fields didn't exist and 2s had at least 1 number. Still a great game though.

I feel ashamed that I've never left a five-star review until today. It's simply one of the best puzzle collections you will ever find, with unlimited replayability and absolutely no annoying ads, nags or distractions of any kind. It's puzzle perfection, and I have to thank you, Chris Boyle, for maintaining it for so long, because you've kept me entertained for years. Edit: Moved files to the SD card and I get an error which says a required file is missing. Reproducible on Samsung A02s.

Solid respectable app, no distractions, no bs. Lots of good puzzles. The controls and descriptions could use some work though. The nonogram puzzle for example is a pain to play using touch controls. I'd advise the programmer to check out picross galaxy (Android) and pictopix (steam) for ideas. Sometimes the descriptions say something is white when it's actually black and it's really confusing. My favorite puzzle in this app is mosaic. Its like a hybrid of nonograms and minesweeper. Good stuff.
