How the Easy, Standard, and Pro Difficulty Levels Work in Hearts Card Classic

Updated

The three difficulty levels in Hearts Card Classic differ only in how the computer players choose their cards — not in what they are dealt or what they can see. At every level, cards are dealt completely at random to you and to the computer players, and the computer gets no special advantage: it does not know your hand or any other player's hand. Easy players pass and play randomly, Standard players follow a fixed set of rules, and Pro players simulate possible unseen-card distributions and pick the play with the lowest average simulated score.

What stays the same at every difficulty

Before comparing strategies, it helps to know what the difficulty setting does not change:

  • Dealing is random. The site states that cards are dealt completely at random for all difficulty levels.
  • No hidden information. Computer players do not know what cards are in your hand or in any other player's hand.
  • No built-in advantage. The computers are not given better cards or extra information — only different decision-making.

So if you lose on Pro, it is because of play decisions, not because the deck was stacked against you.

Easy: random choices

The Easy computer makes no attempt to evaluate its hand:

Phase Easy strategy
Passing Chooses a random set of cards
Playing Chooses a random valid card

This is useful when you want a low-pressure game or are still learning the flow of Hearts, since the computer will not punish mistakes consistently.

Standard: fixed rules

Standard players use a rule-based approach for both passing and playing.

Passing: chooses the three highest-valued cards, where value is determined by card number (Ace, King, Queen, etc.) and suit (Spades, Hearts, Diamonds, Clubs).

Playing:

  • When playing first: chooses the lowest card in hand.
  • When playing 2nd or 3rd: plays the highest card that will not take the trick; otherwise, plays the lowest card of the suit.
  • When playing last, if there are points in the trick: plays the highest card that will not take the trick, or if it must take the trick, plays the highest card of the suit while avoiding the Queen of Spades.
  • When playing last and there are no points in the trick: plays the highest card in hand.
  • When void in the lead suit: plays its highest-valued cards in the order QS, AS, AH, AD, AC, KS, KH, KD, KC, QH, QD, QC, etc.

This produces a predictable opponent — one that avoids taking point tricks when it can, but does not plan ahead beyond the current trick.

Pro: simulation-based play

The Pro computer uses the same passing rule as Standard (the three highest-valued cards by number and suit), but its playing strategy is different in kind:

  1. For each valid play, it simulates random distributions of the unseen cards, taking into account which players are known to be void in particular suits.
  2. In each simulated game, every player finishes the round using the Standard playing algorithm.
  3. It records the final score of each simulated round and computes the average round score for each candidate play.
  4. It plays the card that results in the lowest average simulated round score.

In other words, Pro does not follow a fixed rule — it estimates the consequences of each option and picks the one that looks best on average. That makes it noticeably harder to beat, because it accounts for the cards it cannot see rather than just reacting to the current trick.

Which difficulty should you pick?

  • Easy — if you are new to Hearts, want a casual game, or want to practice passing and following suit without strategic pressure.
  • Standard — if you know the rules and want an opponent that plays sensibly but predictably, so you can learn to read and exploit patterns.
  • Pro — if you want the strongest available opponent and are comfortable with a computer that plans around unknown cards.

A practical note from the site's own explanation: if you find the computer is beating you, understanding how it chooses its next move is likely to help — which is exactly the difference described above.
