Японские кроссворды is a free puzzle game for Android developed by KyberPrizrak. This game has 300 mini-crosswords from the Nonograms.ru website, and if you like them, you can solve additional crosswords for a small fee. The game guarantees that all the crosswords are error-free and have only one solution, which can be achieved without guessing.

This game offers a lot of features, including very flexible crossword design and management settings. The game also has "smart" hints that only open cells according to the rules of solving Japanese crosswords. Additionally, the game has the ability to synchronize saved and solved crosswords with the Nonograms.ru website in both directions. The crossword can be scaled without "blurred lines" and has an assistant function for automatically crossing out numbers (which can be disabled) and filling in the crosses of already solved rows and columns (which can also be disabled). Finally, the game has a sliding panel of numbers (used when the field with numbers is partially off-screen).
