The two rules

In turn 1 Klondike, you flip a single card from the stock to the waste pile, and you can use the top card of the waste. In turn 3, you flip three cards at once and may only play the top one — the other two go under the next batch and wait for a full pass through the deck.

Why turn 3 is so much harder

Turn 1 gives you access to every card in the deck, one at a time. Turn 3 hides two out of every three cards you pass, so a card you needed can slide past you and only reappear after another full cycle. The deck is the same; the access is not.

Win rates depend on how many passes through the deck are allowed, but the gap in practice is large. Turn 1 is forgiving enough to teach the game; turn 3 is where experienced players go for a real challenge.

How turn 3 changes your tactics

Which should you play?

Start with turn 1. It teaches the layout, the alternating-colour stacking and the King-to-empty-column rule without punishing you for every slip. Move to turn 3 once turn 1 stops being a challenge — it is the same game with the safety net removed.
