Klondike, the way you remember it.

Build the four foundations from ace to king. Tap a card, then tap where it goes.

Choose a draw

Tableau piles go down in alternating colours, and only a king starts an empty column. Double-tap a card to send it straight to a foundation. U undoes, A auto-finishes once everything is face up. In Vegas the bankroll carries from deal to deal, so the question stops being whether you can win this hand and becomes whether it is worth another pass through the stock.
