Mystery Riddles 

Mystery Riddles is a fun brainteasing game developed for Mac users who are into solving nonograms on their computers. The objective is to mark the board's cells following the lines and columns indications and reveal the hidden picture.

This app provides you with 200 challenging levels, allows you to create multiple player profiles, and lets you replay missions if you want to. What's more, the game comes with a captivating storyline and nicely-drawn artworks and cinematics.

Another good aspect is that it offers you hints which you can use when you're unsure of which cell should be marked to reveal a piece of the hidden picture. In addition, you're allowed to make a maximum of 5 mistakes per mission (click over an empty cell).

I also like the fact that the app automatically saves your gameplay progress. If you quit to main menu while playing a level, you can resume the gameplay from where you left off.

As a conclusion, I'd say it's definitely worth acquiring this puzzle game for your computer. The app offers many challenges, provides you with plenty of useful hints, and comes with a reasonable price.
