Build all four foundations from Ace up to King, one suit each.
Stack cards down the tableau in alternating colours - a red six goes on a black seven.
Only a King may move into an empty column.
Turn a face-down card over by clearing the cards on top of it; that is how the game opens up.
Out of moves? Draw from the stock, and click it again when it empties to turn the waste back over.
Spider
Challenge with two decks
Build runs from King down to Ace in a single suit. Complete one and it leaves the board; clear eight and you have won.
Any card may sit on a card one rank higher, but only a same-suit run moves as a unit.
Dealing from the stock puts a card on every column at once, so no column may be empty when you deal.
Start at one suit. Two and four suits are the same game with far less forgiveness.
FreeCell
Every card in view
Every card is face up from the start, so nothing is hidden - only awkward.
Build the foundations Ace to King by suit, and the tableau down in alternating colours.
The four cells each hold one card. They are the whole game: how many cards you can move at once depends on how many are free.
Empty a column and it becomes the most valuable space on the board.
Pyramid
Clear the pyramid by pairing cards
Clear the board by pairing cards that add up to thirteen.
Jack is 11, Queen is 12, King is 13 - a King goes on its own.
Only a card with nothing resting on it can be taken.
The waste pile counts: pair a board card with the card you just turned over.
Two boards, same rules: one pyramid of seven rows, or three peaks on a shared row of ten. Choose before you deal.
Keyboard
Space draw a card in Klondike, or ask for a hint in FreeCell
Shift + Space finish the game when it can finish itself
←→ summon the board cursor and walk it across the piles; ↑↓ reach deeper into a fan, then carry the cursor between rows. Esc puts down what you are carrying, and again puts the cursor away
Enter pick up the card under the cursor, then drop it; twice on the same card sends it to the foundation. In Pyramid it presses the card instead - two presses make a pair
