Help is organized in the following sections.
Whist is a 4 player partnership game played with a deck of 52 playing cards. The play is broken down into hands. Hands are played until the game is over. You form a team with the player across from you and accumulate points from each hand played. The game ends when a team reaches 5 points and the team with the highest score wins.
There are three stages to a hand: dealing, playing, and scoring.
At the start of the game the dealer is chosen randomly. From then on, the deal rotates clockwise until the game ends. The cards are dealt evenly to the four players. All cards are dealt face down except for the last card dealt to the dealer, it is dealt face up on the table for all players to see. It determines the trump suit for this hand and remains face up on the table until it is the dealer's turn to play a card on the first trick, at which point it is placed back in the dealer's hand.
The play consists of 13 tricks. Each trick consists of 4 cards, 1 card from each player. For each trick, there is a leader, a suit led, and a winner. The leader is the player who played the first card. The suit led is the suit of the card played by the leader. The winner of the trick is determined by the highest card played of the suit led, however, if a trump was played on the trick, then the winner is determined by the highest trump card played. The ranking of the cards in a given suit is: 2, 3, 4, 5, 6, 7, 8, 9, T, J, Q, K, A.
The player to the left of the dealer makes the first lead and may lead any card from his hand. Play continues clockwise to the left with each player playing a card in turn. Players must play the suit led if they have it otherwise, they may play any card from their hand.
After each player has played a card on the trick, the winning player takes the trick and places it aside until the scoring stage. This player is the leader of the next trick. The play stage continues until players have no cards left in their hands.
After the hand has been played out, the number of tricks taken by each team is counted. The team that took the most tricks receives (number of tricks taken - 6) points. The other team receives 0 points. For example, if you take 8 tricks and your opponents take 5 tricks. You will receive 2 points and your opponents will receive 0 points.
The scores for the hand are added to the total game scores. The first team to reach a total of 5 points wins.
There are many web sites discussing Whist. Here are a few that we found helpful.
NeuralPlay Whist offers many features to help you learn and improve your play. These features may be enabled, disabled, and/or adjusted in settings. The features include the following.
NeuralPlay computer players offer 6 levels of play. Play at level 1 is reasonably easy and good for beginners. Play at level 3 should be fun for most players. Play at level 6 will be the most challenging.
The AI bots employ different AI methods depending on the level. Levels 1 and 2 use simple methods to provide an introduction to beginners. We will not describe them in detail here.
Level 3 uses a rule-based AI. The AI consists of rules such as: "In 3rd seat, do not trump partner's high card" and "In 4th seat, play just high enough to take it when an opponent is winning", etc. We find the rules work quite well and can provide good play.
Levels 4+ use Monte Carlo Simulation to determine the best play. Basically, the AI will deal out the unknown cards randomly. The AI will then try each legal play and play the deal to the end to get a result. This is repeated for many deals of the unknown cards. The average result for each legal play is computed and the legal play with the best average result is chosen.
Levels 4+ differ in how many times the unknown cards are dealt out. In general, the more deals the more accurate the simulation. This results in better quality plays. The trade-off is that more deals take more time, play may be slower on level 6 than level 4 depending on the device.
Since levels 4+ do not use rules, you may observe either surprisingly good plays or odd mistakes that may seem not to follow any logical rules. Overall, our tests show that the levels are better than the rule-based level 3. We also find the randomness makes the computer feel a bit more human-like and fun.
If you prefer a more consistent, logical, and predictable partner AI and/or opponent AI, then level 3 may be best.
We are continuing to research improvements and new computer AI algorithms. We continue to update the bots as we develop improved algorithms.

These terms are used in bridge games. You are always South and your partner is always North. The terms You and South are used interchangeably.
Claim means you will take the remaining tricks. When your hand is clearly high, you may claim the remaining tricks to speed up play. If the claim is successful (the AI will check), you will receive the remaining tricks and the hand will end.
