Fill and Cross. Royal Riddles Free is a puzzle game for Mac that provides you with a wide range of nonograms (picture puzzles). The app gives you access to detailed game instructions so even if you're new to this type of riddles, you can definitely complete the challenges before you run out of time and moves.
Your goal is to mark the board's cells following the line and column instructions accordingly and uncover the hidden binary picture. The game is over if you don't pay attention to the offered level indications (filled and empty squares instructions) and reveal more than one empty square per mission.
Fill and Cross. Royal Riddles Free doesn't provide you with hints or an undo button and lets you to make only two mistakes per level. Personally, I don't find these things as being flaws. The aforementioned aspects make the game even more challenging than it already is.
Another advantage of this application is that it automatically saves your game progress so you don't have to worry about saving each time you complete a challenge.
Briefly, Fill and Cross. Royal Riddles Free is an entertaining yet brainteasing game for Mac. The app is filled with dozens of challenging levels, comes with nicely drawn animations, and plays an enjoyable background music.
