Fairness and probability
The deck is shuffled at the start. Because cards are drawn without replacement, the probability of the next card being higher or lower changes as the game progresses. The hint shows these probabilities based on the visible card and the remaining cards in the deck.
Frequently asked questions
What happens if the next card has the same value?
Ties are counted as correct guesses, which keeps the game moving and rewards close calls.
Can I see which cards remain?
The remaining deck count is shown and the probability hint is calculated from the cards still in the deck.
