Card game guide
Browser Card Games for Different Kinds of Planning
A useful card-game catalog should explain more than the deck count. The main differences are what information is visible, how much temporary space the rules allow, and whether progress means building foundations, removing pairs, or completing sequences.
One deck or two
Single-deck games such as Klondike and FreeCell usually target four foundations. Spider and Forty Thieves use two decks, expanding both the tableau and the number of completed suit runs. More cards do not automatically mean more randomness; open layouts can still be deeply strategic.
Hidden versus open information
FreeCell-style games reveal every card, making them planning puzzles. Klondike and Yukon reveal cards gradually, so good play preserves options while gathering information. Numbered and daily deals reproduce the layout but do not reveal a solution.
Keyboard and touch
Card targets need accessible names, generous hit areas, and a visible focus state. The games here support button-based cards and toolbar actions so the same legal-move engine serves pointer, touch, and keyboard input.

Questions about this collection
Do these games use real-money mechanics?
No. They are free single-player browser games without credits, wagers, or paid outcomes.
What is a foundation?
A foundation is a destination pile usually built by suit in rank order; completing all foundations is the goal of many solitaire variants.
Can a card move back from a foundation?
That depends on the game. Some engines allow a legal return to the tableau, while others make foundation placement one-way.
