Started to like it, but then there were onscreen ads on top of the in between ones. I don't like onscreen ads while playing. Also the autocross for the numbers doesn't work well. Sometimes the amount of blocks are filled, but the number doesn't get autocrossed unless you put a cross between the blocks. Sometimes there can be an other possibilty, but it also happens when there's no other possibility than that the right amount of blocks have been filled to cross out that number.

They took away my favorite part, Large puzzles divided into 4 in an update and then had the nerve to say "we updated the app, we took away 4 part puzzles, we apologize for the inconvenience" like, I paid for this app, I've solved 3-400 puzzles solved and overnight about half of those were removed? why?

We sincerely apologize. To avoid duplication, the four-part puzzles are now only available in Series 1. In Series 2, they have been completely replaced with new puzzles. You can still enjoy the four-part puzzles in Series 1. We deeply regret the inconvenience and kindly ask for your understanding. If you’d like a refund, please send us receipt num.

This is my favorite app for picross. Very relaxing. Controls are very easy to use, no need to try tapping on the tiny squares. New puzzles are added pretty frequently between this and Picross Galaxy 1. I like the black and white picross, because they actually look like pictures, unlike the full color puzzles on other apps that don't look like anything until color is added.
