Grimes is an unusual and challenging solo card game. Easy to learn but hard to master, Grimes requires a combination of strategy, memory, concentration and a bit of luck.
The app plays both Grimes patience and classic sevens solitaire (Demon). It includes walkthroughs on how to play each game.
Hints are available if you are stumped and unlimited undos allow you to go back and try something different.
The score history lets you see the pattern of your past Grimes scores and how your latest hand compares.
