Solitaire
Klondike, draw one or three. Drag, click or play it from the keyboard.
Cleared.
No legal moves remain — undo a few, or deal a new game.
Drag a card, or click it and then click where it should go. Double-click finds the card a home on its own — its foundation if it can, otherwise a build it fits, and an empty column for a King. Keyboard: tab to a card, press Enter to pick it up, tab to a pile, press Enter to drop. Escape cancels. Your game is saved in this browser, so you can close the tab and come back to it.
