Progressive Jackpot

A progressive jackpot is a jackpot highest payoff for a gaming machine usually a slot machine or video poker machine where the value of the jackpot increases a small amount for every game played. Normally multiple machines are linked together to form one large progressive jackpot that grows more quickly because multiple players are contributing to the jackpot at the same time.

The amount of the jackpot is shown on a meter as a money value. Usually the jackpot can only be won by winning the combination with the highest payoff, e.g. a royal flush at a video poker game, or five of the most valuable symbols lemons, cherries, alligators, etc on a slot machine. Once a player wins the jackpot, the jackpot resets to a preset minimum level.

The amount on the jackpot progresses increases a small amount for every play on a connected machine. The amount that the jackpot advances by is set by the casino the house. For example, on a machine whose house edge is 5%, a generous jackpot contribution might be 1% one fifth of the expected profit. The house is prepared to contribute some of the profit of a jackpot linked machine because players are attracted by the:

Relative novelty of progressive jackpots generally, only a small fraction of the house's gaming machines will be connected to a progressive jackpot

Constantly changing meter, often displayed on large LED or LCD displays

Large amount of the jackpot, which eventually motivates more players to play the game

Usually only players who wager the maximum number of credits per play qualify to win the jackpot. All wagers, whether or not they are maximum credit bets, contribute to the jackpot though. As a result, a game which requires a 10 credit wager to qualify for the progressive jackpot will tend to have the progressive jackpot rise to higher levels relative to its break-even level than a game that requires only a 5 credit wager to qualify.

In some games such as video poker, it is possible to compute an optimal playing strategy based on the frequency for each payoff versus the odds of hitting that payoff. Since the jackpot of a progressive video poker game is constantly growing, it eventually can reach a break-even point where the machine becomes a positive expectation bet for the player.

When the progressive jackpot is less than the break-even point, there is a negative expected value house edge for all players.

In the long run, with optimal strategy, a video poker player can make a profit, although the long run is generally longer than most people think. Several tens of thousands of plays.

It is worthwhile to note that a break-even point cannot be easily calculated on a slot machine game, because the payback percentage for the game is normally unknown to the player. The break-even point in video poker can be calculated because the payback percentage for the game is a function of the paybacks and odds of the poker hands, which is based on a standard 52 card deck. The return of a slot machine is based on the published paytable, but also on the normally unpublished reels. For a five reel slot machine, the player would need to know each symbol on each of the slot machine's five reels, in order to calculate the odds. For a three reel slot, the reels are normally weighted, and this would not be possible. However, in some circumstances the manufacturer may publish the payout of their machines.

Shuffling

Shuffling is a procedure used to randomize a deck of playing cards to provide an element of chance in card games. Shuffling is often followed by a cut, to help ensure that the shuffler has not manipulated the outcome. A common shuffling technique is called the riffle or dovetail shuffle, in which half of the deck is held in each hand with the thumbs inward, then cards are released by the thumbs so that they fall to the table interleaved. Many also lift the cards up after a riffle, forming what is called a bridge which puts the cards back into place. This can also be done by placing the halves flat on the table with their rear corners touching, then lifting the back edges with the thumbs while pushing the halves together. While this method is more difficult, it is often used in casinos because it minimizes the risk of exposing cards during the shuffle. There are two types of perfect riffle shuffles: if the top card moves to be 2nd from the top then it is an in shuffle, otherwise it is known as an out shuffle which preserves both the top and bottom cards.

Riffle shuffling does, however, carry a risk of damaging cards from excessive bending. Casinos often replace their playing cards to prevent cheating from players that detect deformations in the cards. However, collectible card game cards are considerably less replaceable than playing cards, and CCG cards can be damaged from riffle shuffling, even when protected with card sleeves.

Because standard shuffling techniques are seen as weak, and in order to avoid inside jobs where employees collaborate with gamblers by performing inadequate shuffles, many casinos employ automatic shuffling machines. They also save time that would otherwise be spent shuffling, allowing several more hands per hour to be played and increasing the profitability of the table. These machines are also used to lessen repetitive motion stress injuries to a dealer. Note that the shuffling machines have to be carefully designed, as they can generate biased shuffles otherwise: the most recent shuffling machines are computer-controlled, though they have not yet fully been integrated into gaming.

 

Bastra

 

Bastra, the Greek deformation of the Arabic word Basra, which is also a similar game played in Egypt, Lebanon and other Middle-Eastern countries, is a popular fishing card game similar to Cassino very popular in Cyprus.

The game was probably introduced to the Cypriots through the Turks during the Ottoman occupation. There are also variations of the game played in Greece, such as Diloti and Kseri. The game has been exported by both the Cypriot and Turkish diasporas and is played in Cypriot communities in Australia, Canada, England and the United States, usually passed on by the first generation of immigrants to their children and grandchildren. Despite this, the game is virtually unknown in these countries outside of the Cypriot and Greek communities. In Turkey the game is still very popular.

The game is played with a 52 card deck and can involve two, three or four players, although the game is most interesting in the two or four player versions. In the four player version, the players can play for themselves or in two player teams. The first team or player to score 100 points is the winner.
The play

The dealer starts by dealing 1 card to each player, starting with the player on the dealer's left, until each player has 4 cards. The dealer then places 4 cards in the middle of the table, called the board. If 1 or more of the 4 cards is a jack, the dealer returns the jacks to the bottom of the deck and replaces it or them with the next cards from the top of the deck. The play begins with the player to the dealer’s left until all cards are played out. The players either collect fish cards from the board or add a card to the board if they cannot fish any cards. After the cards are exhausted, the dealer then deals each player 4 more cards from the remaining deck. The dealer, however, does not deal 4 cards onto the board as done for the opening hand. The hands are played out until there are no remaining cards to be dealt.

In the two player version, each round has six hands, in the three player version, each round has four hands, and in the four player version, each round consists of three hands.
Scoring

The scoring is as follows:

    The aces, which have a numeral value of 1, are worth 1 point each.
    The jacks are worth 1 point each.
    The two of clubs is worth 2 points.
    The ten of diamonds is worth 3 points.
    The player or team that collects the most cards in a given hand receives 3 points. In the event of a tie, each player or team receives 3 points.
    The player or team that collects all the cards in play without benefit of a jack receives 10 points, or a bastra.

Collecting cards

The object of the game is to collect total cards and cards that are worth various points. Cards are collected as follows:

    Pairing: Any card may be used to take another card or cards of the same denomination, i.e. a 7 takes a 7, a king takes a king, a 6 takes two 6s, etc.
    Combining: Multiple cards may be collected through adding the numeral value of the cards together. For example, the board shows 2, an ace, 5 and 4. A player with a 3 could take 2 and the ace 2+1=3, or a player holding a 9 could take 5 and 4 5+4=9, or a player holding a 7 could take 2, the ace and 4 2+1+4=7.
        A player may also collect combinations of the same sum. For example, if the board shows 5, 4, 2 and 7, a 9 would take all 4 cards, i.e. 5+4 and 2+7=9.
    Pairing and combining: Taking cards through pairing and combining can occur on the same play. For example, if the board showed 3 6 5 4 and 9, a 9 would take all the cards, i.e. 3+6 and 5+4=9, plus the 9 would be paired with the 9.

On the last hand, there are often uncollected cards left on the board. These cards are awarded to the last player or team to collect a card.
Jack

The jack is the most powerful card because it can collect all the cards on the board. However, if a jack is played onto an empty board, it is lost and remains in play until one of the players can collect it, usually with another jack.

 

The bastra is the most important scoring play of the game since it is worth 10 points. A bastra occurs when a player succeeds in clearing the board without benefit of a jack. For example, if the board shows just a 7 and a player collects it with another 7, that player or team receives 10 points. In another scenario, if the board shows 3 and 2 and a player collects them with a 5, that player or team also receives 10 points. In the rare event that a jack takes a solitary jack, a 50 point bastra is awarded.

 

The players place the collected cards close to their position at the table. To record bastras, the player places the bastra card face up, sticking out of the player's pile of collected cards. The dealer should be careful to place his or her collected cards away from the deck, so as to avoid confusion. Players are not allowed to look at their collected cards until the end of the hand. At the end of the hand, the players count their total cards and points.

 

The game ends when one player or team reaches 100 points. In the rare event of a tie 2 players or teams finish even beyond the 100 point mark there are various tie-breaking options, determined by the players by mutual consent. The game can be declared a draw, or an extra hand or hands can be played until the tie is broken. Or the players can extend the game to a fixed number of points 20, 30 or 50.
