I have several family members (myself included) who are self-diagnosed solitaire addicts. Now we leave our well-worn decks at home, and enjoy a quick game, no matter where we roam.
From FreeCell (the Windows classic) to Klondike, Golf, Spider and 98 more (that's 102 in all), Tesseract Mobile's Solitaire MegaPack is truly the cream of the crop of mobile solitaire applications for your Android phone.
Playing each version of Solitaire is a snap. Once the cards are laid, just click one to select it, then tap where you want it to go. Drag and drop is also enabled.
To move part of a card stack, double-tap on the top of the stack, then tap where you wish to drop it. Double tapping anywhere on the screen will put the stack back where you grabbed it from.
Don't miss the options menu if you want to use larger cards. If you're getting up there in age, or simply want to make it easier to see each card, I highly recommend turning this on as your very first step upon launching the game. Choosing from the available backgrounds will also bump up the overall legibility of the cards.
The latest update brings a handy game toolbar (undo, redo any play), new sorting options that make it easier to view all game types, smoother overall gameplay and tons of user interface tweaks.
All of these items were direct requests from paying customers, and you have to give any app developer (thanks, Tesseract Mobile!) full marks for listening, tweaking, and releasing a steady stream of updates to already-popular offerings.
