Then, ten tricks are played, allowing players to take trick points. Each card has a face value except in null games and is worth that number of points for the player winning the trick.

The total face value of all cards is points. The declarer's goal is to take at least 61 points in tricks in order to win that round of the game.

Otherwise, the defending team wins the round. Points from tricks are not directly added to the players' overall score, they are used only to determine the outcome of the game win or loss for declarer , although winning by certain margins may increase the score for that round.

After each round a score is awarded in accordance with the game value. If the declarer wins they are awarded a positive score, if they lose the score is doubled and subtracted from the declarer's tally i.

In tournaments a winning declarer gets an additional 50 points if they win, if the defending team wins however they receive 40 points each in addition to the declarer losing twice the game's value in points.

The deck consists of 32 cards. Some players in Eastern and Southern Germany and Austria prefer traditional German decks with suits of acorns , leaves , hearts and bells , and card values of deuce Daus , king König , Ober , Unter , 10, 9, 8, and 7 in all four suits.

By contrast, regions of the former West Germany had adopted a French-suited deck. At the beginning of each round each player is dealt ten cards, with the two remaining cards the so-called Skat being put face down in the middle of the table.

Dealing follows this pattern: deal three cards each, then deal the Skat , then four cards each, then three cards again "three— Skat —four—three". In four-player rounds, the dealer does not receive any cards and skips actual play of the round.

He or she may peek into the hand of one other player if allowed to do so but never into the Skat. Dealing rotates clockwise around the table, so that the player sitting to the left of the dealer will be dealer for the next round.

After the cards have been dealt, and before the deal is played out, a bidding or auction German : Reizen is held to decide:. The goal for each player during the bidding is to bid a game value as high as their card holding would allow, but never higher than necessary to win the auction.

How the actual game value is determined is explained in detail below and is necessary to understand in order to know how high one can safely bid.

It is possible for a player to overbid, which leads to an automatic loss of the game in question. Often this does not become obvious before the player picks up the Skat , or even not before the end of the game in question in case of a hand game, when the Skat is not picked up.

Players have therefore to exercise careful scrutiny during bidding, as not to incur an unnecessary loss. The bidding may also give away some information about what cards a player may or may not hold.

Experienced players will be able to use this to their advantage. The game value also called hand value , German : Spielwert is what the game will be worth after all tricks have been played.

It is determined not only by the 10 cards held, but also by the two-card Skat. The Skat always belongs to the declarer, and if it contains certain high cards this may change the game value.

It is therefore not possible in general to determine the exact game value before knowing the Skat. The game value is determined by the type of the game and the game level as explained below for the suit, grand and null games.

In a suit game German : Farbspiel , one of the four suits is the trump suit. Each suit has a base value German : Grundwert , as follows:.

This base value is then multiplied by the multiplier game level German : Spielstufe or Gewinngrad to determine the game value, so:.

The multiplier game level of 1 for becoming declarer is always assumed. It is then increased by one for each of the following:. In case of a Hand game declarer does not pick up the Skat , the following special cases are allowed.

Each one increases the multiplier game level by another point:. Cards in the trump suit are ordered as follows this is important to know when counting the length of the matador's jack straight :.

As mentioned above, the cards in the Skat are to be included when determining the multiplier game level also in case of the Hand game, where the Skat is unknown until after the deal has been played out.

During bidding, each player therefore has incomplete information regarding the true game value. The final game value is calculated by multiplying the base value for the suit by the multiplier game level:.

Grand game is a special case of suit game, in which only the Jacks are trumps in the same order as in the suit game:. The base value for the grand game is 24 in the official rules.

It used to be 20 until , and many hobbyists continued to use 20 well into the postwar era. All other rules for determining game value are as in a suit game, that is, the base value of 24 is multiplied by the multiplier game level.

In the null game, declarer promises not to take any tricks at all. There is no trump suit, 10s are sorted directly above 9s, and jacks are treated as normal suit cards sorted between 10 and queen.

Thus the cards are ordered: A-K-Q-J The game values of null games are fixed, as follows:. The following examples give a player's holding and the contents of the Skat which will be unknown to all players during the auction and explain how to derive the game value.

The multiplier game level will be 2 1 for matador's jack straight plus 1 for becoming declarer. Note that game value is dependent not only on the cards held including the Skat but also on which game is being declared and the outcome of the play.

Each holding can thus be evaluated differently by different players. A risk-taking player might be willing to declare Hand on a holding on which another player might not — these two players will therefore give different valuations to the same holding.

However, after all tricks have been played, it is always possible to determine the exact game value by combining the actual holding with the type of game and outcome of the play.

Only then it becomes apparent if declarer has won or lost if he overbid. Assuming a trump suit of hearts in a suit game, this holding will have a different valuation before and after the Skat has been examined.

With Hearts as trump, the game value will always be at least that much. Now, assuming declarer wins by taking 95 points in tricks, after having declared Hand and Schneider , the actual game value will be as follows:.

The player could have bid up to that value during the auction. Now for the special cases: if you think you can do more than just win, you can add points for the special cases.

The highest possible multiplier game level is that is with or without four jacks and all seven cards of trump suit including those in the Skat , if any 11, plus the maximum of 7 for becoming declarer, Hand , Schneider , declaring Schneider , Schwarz , declaring Schwarz and Ouvert.

The order of bidding is determined by the seating order. Starting from the left of the dealer players are numbered clockwise: the first seat German : Vorhand , the second seat German : Mittelhand and the third seat German : Hinterhand.

In a three-player game, the dealer will be the third seat. In a four-player game the third seat will be to the right of the dealer.

Bidding starts by the player in second seat making a call to the player in first seat on which the latter can hold or pass.

If the first seat player holds, the second seat player can make a higher call or pass himself. This continues until either of the two players passes.

The player in third seat is then allowed to continue making calls to the player who has not yet passed. Bidding ends as soon as at least two players have passed.

It is also possible for all three players to pass. The player who continues in this mnemonic is either the dealer in a three-player game or the player in third seat.

The mnemonic is commonly used among casual players. Example: Anna, Bernard and Clara are playing, and seated in that order around the table.

Anna deals the cards. Clara makes the first call to Bernard, who passes right away. Anna then makes two more calls to Clara, who accepts both bids.

Anna then passes as well. The bidding ends, with Clara being the declarer for this round. Except for "pass", only the possible game values are legal calls.

Therefore, the lowest possible call is 18, which is the lowest possible game value in Skat. Players are free to skip intermediate values, although it is common to always pick the lowest available call while bidding.

The sequence of possible double digit game values, beginning with 18 is 18—20—22—23—24—27—30—33—35—36—40—44—45—46—48—50—54—55—59— triple digit bids are possible albeit rare in a competitive auction.

Also, numbers are frequently abbreviated by only calling the lower digit of a value not divisible by 10 e. As the German words for "null" and "zero" are identical, this yields the rather unintuitive sequence 18—20—2—0—4—7—30 and so on.

If all players pass, the hand is not played and the next dealer shuffles and deals. A dealer never deals twice in a row. It is common in informal play to play a variant of Skat called Ramsch junk, rummage instead of skipping the hand and dealing for the next one.

This is not part of the sanctioned rules, however. In a pass-out game, the player in first seat will be the last one to pass.

If that player intends to become declarer, however, he has to make a call of at least 18 picking up the Skat in that situation implies the call.

Players Anna, Bernard and Clara are seated in that order, clockwise; Anna is the dealer. The auction proceeds as follows:. The winner of the auction becomes declarer.

He will play against the other two players. Before the hand is played, declarer either. After putting two cards back into the Skat , declarer then either declares a suit game by announcing a trump suit, declares a grand game or a null game.

If Hand has been declared, the player may make additional announcements such as Schneider , Schwarz and Ouvert.

A common variant in non-sanctioned play allows the defenders to announce " Kontra " just before the first trick is played, if they have made or held at least one call.

In this case, the stakes will be doubled for the hand. In a less common further variation this process can be repeated twice more by announcing " Supra " and " Resupra " or more colloquially, " Bock " [ roe buck] and " Hirsch " [red deer] , or the like, which are colloquial augments of " Reh " roe deer.

The player in the first seat sitting to the left of the dealer leads to the first trick. The other two follow in clockwise direction.

Every player plays one card to the trick, which is in the middle of the table. The winner of a trick stacks the cards face down in front of him and leads to the next trick, which is again played clockwise.

Completed tricks are kept face down in front of the players who won them, until all the cards have been played. Examining completed tricks except for the last one is not allowed.

The tricks of the two players who are playing together are put together, either during or after play. If a player cannot follow suit, he may play any card including a trump card.

Trumps, including all four jacks, count as a single suit. If a trump is led, every player must also play trump, if he has any. If there are trump cards in the trick, the highest trump in it wins the trick.

If there are no trumps in it, the highest card of the suit led wins the trick. The non-trump suit cards rank in order AK-Q In the grand game, only the four jacks are trumps in the suit order given above for a regular suit game.

All other ranks are the same as in the regular suit game 10 is ranked just below the ace. There are thus five "suits" in the grand game if a jack is led to a trick, the other two players must play jacks too, if they have them.

The goal of a null game is for declarer not to take any tricks. If declarer takes a trick in a null game, he immediately loses and the game is scored right away.

Declarer may, unilaterally, concede a loss while he is holding at least nine cards i. Afterwards approval of at least one defender is required.

Only then it becomes apparent if declarer has won or lost if he overbid. Assuming a trump suit of hearts in a suit game, this holding will have a different valuation before and after the Skat has been examined.

With Hearts as trump, the game value will always be at least that much. Now, assuming declarer wins by taking 95 points in tricks, after having declared Hand and Schneider , the actual game value will be as follows:.

The player could have bid up to that value during the auction. Now for the special cases: if you think you can do more than just win, you can add points for the special cases.

The highest possible multiplier game level is that is with or without four jacks and all seven cards of trump suit including those in the Skat , if any 11, plus the maximum of 7 for becoming declarer, Hand , Schneider , declaring Schneider , Schwarz , declaring Schwarz and Ouvert.

Declarer may, unilaterally, concede a loss while he is holding at least nine cards i. Afterwards approval of at least one defender is required.

Defenders may concede at any time, but may be requested by declarer to complete the play e. Claiming of remaining tricks is possible as well, but for a defender only if she would be able to take the remaining tricks herself.

After the last trick has been played, the game is scored. Winning conditions for null game are different from suit and grand games.

To win a suit or grand game, declarer needs at least 61 card points in his tricks. If declarer announced Schneider , he needs at least 90 card points in order to win.

The two cards in the Skat count towards declarer's tricks. If declarer announced Schwarz , he must take all ten tricks in order to win.

The best option is the last one. As an example, Java applies the last option for local variables. Hence, the following code results in a compile-time error at the second line:.

The basic rule is simple: null should only be allowed when it makes sense for an object reference to have 'no value associated with it'. For example, suppose type person with fields name and dateOfFirstMarriage :.

Every person has a name. Field name is non-nullable. It is illegal to assign null to it. On the other hand, field dateOfFirstMarriage doesn't represent a required value.

Not everyone is married. Hence it makes sense for dateOfFirstMarriage to have 'no value associated with it'.

Therefore dateOfFirstMarriage is a nullable field. If a person's dateOfFirstMarriage field points to null then it simply means that this person has never been married.

There is no way to reliably state that null can never be assigned to a given object reference. In some languages it is possible to use annotations, such as the non-standard annotations Nullable and NonNullable in Java.

Here is an example:. However, such annotations are not used by the compiler to ensure null-safety. Still, they are useful for the human reader, and they can be used by IDEs and tools such as static code analyzers.

Consider a function that reads configuration data from a file. Many languages C , Java, etc. Instead, the function's signature should be changed in order to make it clear that the function might fail:.

Allow null only if it makes sense for an object reference to have 'no value associated with it'. At run-time, the above code results in the infamous null pointer error , because we try to execute a method of a reference that points to null.

It is the most frequent bug in many software applications, and has been the cause for countless troubles in the history of software development.

Tony Hoare, the inventor of null , calls it the 'billion-dollar mistake'. But Tony Hoare Turing Award winner in and inventor of the Quicksort algorithm , also gives a hint to a solution in his speech :.

Contrary to some common belief, the culprit is not null per se. The problem is the lack of support for null handling in many programming languages.

For example, at the time of writing May , none of the top ten languages in the Tiobe index natively differentiates between nullable and non-nullable types.

Therefore, some new languages provide compile-time null-safety and specific syntax for conveniently handling null in source code.

In these languages, the above code would result in a compile-time error. Software quality and reliability increases considerably, because the null pointer error delightfully disappears.

Hence, null pointer errors cannot occur. If this article was helpful, tweet it. Learn to code for free. Get started. Stay safe, friends. Learn to code from home.

Use our free 2, hour curriculum. Introduction null is a fundamental concept in many programming languages. Run-time Implementation Before discussing the meaning of null , we need to understand how null is implemented in memory at run-time.

To keep things simple, we will make the following assumptions: The above instruction is executed on a bits CPU with a bits address space.

Strings are encoded as UTF The following picture shows an excerpt of the memory after executing the above instruction: Figure 1: Variable name points to "Bob" The memory addresses in the above picture are chosen arbitrarily and are irrelevant for our discussion.

So far so good. And this is the new state in memory: Figure 2: Variable name points to null We can see that nothing has changed for the string "Bob" which is still stored in memory.

Remember: If a reference points to null , it simply means that there is no value associated with it.

Performance As we learned in the previous section, operations involving null are extremely fast and easy to perform at run-time.

There are only two kinds of operations: Initialize or set a reference to null e. Check if a reference points to null e. Remember: Operations on null are exceedingly fast and cheap.

Reference vs Value Types So far we assumed working with reference types. Remember: The concept of null exists only for reference types. Meaning Suppose we have a type person with a field emailAddress.

Not necessarily. Or… Alice has an email address, but: it has not yet been entered in the database it is secret unrevealed for security reasons there is a bug in a routine that creates a person object without setting field emailAddress and so on.

Remember: If a reference points to null then it always means that there is no value associated with it. Why is it null?

Sometimes it is important to know why a reference points to null. This is bad data design for multiple reasons. So the function needs to return more information than just a list.
