Klondike solitaire

Play draw-one Klondike by dragging cards between the tableau and foundations.

Click the stock to turn one card. When it is empty, click it again to recycle the waste pile. Drag a face-up card or a descending run to a tableau column. Build tableau columns in alternating colours, from King down to Ace. Drag one card to its suit foundation to build from Ace up to King. Only a King can fill an empty tableau column. Hover over a partly covered face-up card and it pokes up from its stack so you can read more of it.

Click a top card to move it to a foundation when the move is legal. The card glides to its foundation over a quarter of a second. Press N for a new game, or Space to draw from the stock. The game allows unlimited stock passes. It does not yet have undo or scoring.

When you win, the cards bounce off the foundations one by one, Kings first, and leave trails across the table like Windows Solitaire. Click to skip to the end, then use the New game button in the "You won!" panel to deal again.

To replay an initial deal in another host, call uniform_set_seed(u32) before the first render(0). The same nonzero seed produces the same shuffled deck.
