Mystery Solitaire integrates classic cases of murder and mayhem into a mix-and-match multi-deck twist on the classic game of Klondike/Patience. Take on the role of a sleuth and choose which case you will solve. Shuffle your deck of 52 cards together and you are ready to play! Use the abilities on Sleuth cards to help with the investigation while negotiating the obstacles presented on Crime cards. Win by playing all cards from your deck and tableau. A single deck provides hours of single player enjoyment. However, multiple decks allow players to mix-and-match characters as well as unlocking the ability to play a two-player variant. Will you alone find the clues?
