The classic Klondike. Build the four piles up from Ace to King by suit. Tap a card, then tap where it goes — no dragging needed. Double-tap a card to move it automatically — to the top piles, or to a column where it fits.
Stuck? A hint plays a helpful move but adds 30 seconds to your time. Near the finish, a free Auto-finish button appears to tidy up the rest.
