Knight Solitaire. Royal Cup is a card game for Mac that keeps you glued to the screen with its numerous challenges, stunning artwork, and plenty of power-ups. This application is suitable for users of all ages with or without experience in playing Solitaire games.
The game comes with a very comprehensive help guide where you can learn how to complete missions and use power-ups. After you check the manual, you can start playing the missions, configure game options according to your needs (change deck appearance, change sound settings, etc.), and buy power-ups from the shop window (you use coins collected during the missions).
As you complete a level, the next mission is unlocked and so on. I like that you can create multiple player profiles and the app automatically saves the game progress for each user.
Another good aspect about this game is that it doesn't ask you to pay extra money (real money) for additional power-ups like other apps of its kind do. Knight Solitaire. Royal Cup lets you use the coins you collected playing its levels for acquiring power-ups.
To sum things up, I can't find any reason why you shouldn't at least try this Solitaire game. The app is filled with a wide range of missions, offers you plenty of hints and power-ups, and comes at a small price.
