If you only had time to download and play 1 game this year, 100² Logic Games-More puzzles by Andrea Sabbatini would probably be that. There are 50 new games and each has 200 levels.
I really like the game called Planets (see first picture.) Each row and column must have a sun and a cloud to block the sun. Of the 200 levels I have solved about 75.
But: at least 10 levels of this game had several solutions. But the program only recognizes one.
This game is a nice variation on Akari from 2012.
Andrea: fantastic job!
