Deal or No Deal (Australian game show)

Occasionally at the end of the program a Super Case is brought out. This feature was introduced in 2004. Contestants have the opportunity to either keep the deal they made or forfeit it and take whatever value is hidden in the Super Case. The Super Case contains one of the following values: 50c, $50, $500, $5,000, $10,000, $20,000, $30,000 & $50,000. (In 2005 the amounts were, 50c, $100, $500, $1,000, $10,000, $20,000, CAR & $50,000. For Double Deal Friday the amounts were, 50c, $100, $1,000, $2,000, $5,000, $10,000, $20,000 & $30,000). Super Cases appear in most episodes when contestants take a deal of approximately $10,000 when there are at least five cases left on the board, and rarely appear in any other circumstances. This means that the Super Case offers a 50/50 chance at bettering or equalling the $10,000 deal. If contestants take a $10,000 deal with fewer than four cases left on the board, Super Cases are rare because there is not generally any time left in the show to run it. During the 2006 season, the way of telling the contestant that a Super Case will be brought out changed, where instead of the Super Case panel flashing, a Super Case alert flashes beside the 'Cases remaining' panel, and remains there until it is actually brought out. In 2010 the Super Case has been used more frequently.

This feature was introduced in 2004. A Chance is an opportunity for the contestant to exchange the deal they took during the game for whatever is in their briefcase. It happens rarely, and only when the two remaining unknown case values are an extremely small amount and an amount of at least $5,000. For example, the contestant takes a deal of $6,500, but is offered a Chance with the remaining unopened briefcases being $750 and $10,000. If the contestant takes the Chance, they win either $750 or $10,000, depending on which value is in their selected briefcase. If they don't take the Chance, they keep their $6,500 deal.

Double or Nothing was added in 2006. If a contestant is lucky enough to play it, two suitcases (labeled I and II) are offered to the contestant; one has the word "Double" inside, the other has "Nothing". If the contestant chooses to play they must pick one of the cases. If Double is in the chosen case, the contestant doubles their winnings. If Nothing is in the chosen case, they lose all their winnings.

The format for Double or Nothing has been altered several times. When it was first introduced, there was only one case brought out (which was the same case as the Super Case). It had only either "Double" or "Nothing" inside, and the contestant could choose how much to gamble. If "Double" was inside, the contestant wins how much they gambled as a bonus. If "Nothing" was revealed, they would lose how much they gambled from their Deal. The "two cases" format was introduced on 23 June 2006. During the 2007 season, Double or Nothing returned, though the contestant could no longer choose how much to gamble, instead having to risk their entire Deal if they wanted to play Double or Nothing. If the contestant opens the case with "Nothing", they do not win any money.

Risk it All was introduced in 2010. This feature allows the contestant who took a deal for under $10,000 and has only two amounts smaller than their deal in play, to win a cash prize of $15,000. If the contestant takes the Risk it All, they can guess which amount is in their case. If they guess correctly, they win the $15,000. If they guess incorrectly, they lose all their winnings.

Switch Case was introduced in 2010. At any point during the game, the banker may offer this switch. If the contestant takes it, they can swap their chosen case for any unopened case on the podium. It usually occurs during the middle of the game.

Dash for Cash was introduced in 2013. Near the end of game if the contestant has a maximum prize of $5,000 or less the banker may offer a prize around half of the current maximum prize on the board rather than a normal offer. There are usually two more prizes higher than this offer. The contestant may take the money and will forfeit the remainder of the game.

Second Chance was introduced in 2013. At the end of the game on rare occasions the banker may offer a second chance. A dealette gives a button to the contestant, who can press it to swap their done deal and for one of the amounts offered to him during the game, selected at random.

This feature was introduced in 2004. At random intervals during the game, the bank will offer a "Mega-Guess", which increases the "correct guess" bonus for the next case to either $2,000, $5,000, or $10,000. The Mega-Guess is usually used at the end of the game to fill in remaining time. This generally happens when the podium player is a friend or relative of the main contestant. The end of game Mega-Guess has adopted a small gag where either the podium player, main contestant, or O'Keefe himself must beg the banker to give the player a Mega-Guess.

The Mega-Guess feature has been altered several times during its history. When first introduced, during the $12 Million Month special, it had a fixed amount win of $10,000. When it returned in the 2005 season, the amount won was reduced to $5,000. In the 2006 season, it was altered to its current format, where either $2,000 (Blue), $5,000 (Maroon), or $10,000 (Green) could be won. The $5,000 Mega-Guess has the most common appearance, sometimes showing up several times during a game, followed by the $10,000 Mega-Guess which would appear once early during the game, and sometimes at the end. The $2,000 Mega-Guess usually appears for podium players celebrating birthdays or people from states other than Victoria after a contestant selects them.

In July 2008, a $25,000 Mega-Guess was offered for the 25,000th case opened in the show's history, but it was not won.

This feature was introduced in 2004, but was removed in 2006. One of the briefcases (except for the CAR, $100,000 or $200,000 cases) contained gold-coloured dollar signs around the cash value inside the case. The person who was holding this case (be it a podium player or the contestant) received the Daily Prize of $500. The Daily Prize was removed in 2006, although prizes were still awarded several times during that year: in a special Saint Patrick's Day-themed episode; on Mother's Day; and during the last week of the 2006 season.

Double Deal Friday ran in 2005 but was dropped after 2008. Home viewers were invited to ring a phone number charged at $0.55 and register their details. Every Friday, a home viewer was randomly selected to win the same prize as the studio contestant. Host O'Keefe had mentioned that Double Deal Fridays received over 100,000 calls each week. Dancing with the Deals (the celebrity version of DoND retiring contestants on that season's edition of Dancing With The Stars) followed a similar format to Double Deal Friday, except that the celebrity didn't win the prize.

Deal or No Deal – Double Shot was a series of specials where the podium contains two briefcases with $200,000 inside them instead of one giving the contestant a 1 in 13 chance of selecting the top prize. The additional $200,000 is in replacement of the 50c amount. These set of episodes have said to answer to the premiere of Million Dollar Wheel of Fortune on the Nine Network, which aired at the same time as Deal or No Deal (except in Queensland when Wheel will air at 5pm due to Extra airing at 5:30pm). A similar special aired in 2004 for the show's 200th episode, with two $200,000 cases; however, the second $200,000 case replaced the $1,500 amount rather than the 50c. Also, for the podium players, should a contestant guess that there's $200,000 in their case, they must specify whether it's the actual $200,000, or the "Double Shot" $200,000 to prevent them from having a 2 in any chance of winning $500. In the 10 episodes aired, the total amount of money won by the contestants was $235,100; neither of the $200,000 cases was selected. The large fake cheques with removable numbers handed out at the end of each game also had a special new look for this series. In an odd coincidence, on the first two games aired after the special ended, one contestant won $100,000, and the next picked selected the $200,000 case but dealt during the game.

Ten more Double Shot games were aired in the 2009 series during late April and early May. These set of episodes have said to answer to the premiere of Hot Seat on the Nine Network, which aired at the same time as Deal or No Deal. The total amount of money won to the contestants was $201,865. The $200,000 Double Shot was finally selected by a contestant on 29 April 2009 who took a deal for $30,000. Cheques used after the games were the standard blue instead of the special gold colour that was used in the 2008. The biggest winner was $40,000 on April 20 who won that amount despite losing both $200,000 cases earlier in the game.

Five more Double Shot specials aired during 19–23 July 2010 as part of a 'Christmas in July' week. The total amount of money won during the week was $115,010, which includes a $10,000 Megaguess.

Five more Double Shot specials aired during 22–26 November 2010 as part of a Hawaiian theme week. The total amount of money won during the week was $136,150.50. Amazingly, one contestant got the $50,000, $75,000 and $100,000 as the last three cases left. He played on and lost the $75,000, and was offered $75,000. The contestant played to his case on won the $100,000. The Supercase was also bought out twice during the week, and both contestants took it when it was offered. One contestant managed to win $20,000, but another lost all his money and won 50c.

Five more Double Shot specials aired during 18-22 July 2011 as part of another 'Christmas in July' week. The total amount of money during the week is $153,500.

On the 12 September 2011, a single Double Shot special aired celebrating the premier of Johnny English Reborn. The contestant dealed for $80,000, but his case contained the Double Shot $200,000.

Deal or No Deal – Fantastic Four was a series of specials that first aired during 21 – 26 September 2009 and then randomly throughout the year, where the podium contained two briefcases with $50,000, $75,000 and $100,000 and a briefcase containing $250,000 giving the contestant a nearly 25% chance of selecting one of them. The additional $50,000 replaces the 50c amount, $75,000 replaces the $750 amount, $100,000 replaces the $1,000 amount and the $250,000 replacing the $200,000 amount.

In the first 5 episodes aired, the total amount of money given away was around $124,000. Surprisingly, the "Fantastic" $75,000 case was selected twice in the week. The highest amount of money won was $41,000, despite losing the "Fantastic" $50,000 and $75,000, plus the regular $100,000 in the first round and the "Fantastic" $100,000 plus the regular $75,000 in the second. Amazingly one contestant had the $150, "Fantastic" $75,000 and both $100,000s in play and was offered $46,000. She then lost the $100,000s in the next two rounds and was offered $36,000. She dealed and was one of the two to have the "Fantastic" $75,000 in her case. One contestant also dealed for $14,000 and risked it and won $20,000 in the Supercase.

On 31 January to 7 February 2011, a series of Las Vegas Fantastic Four specials aired. Because of Seven News' extended coverage of Cyclone Yasi, the 2 February episode did not air, so the specials had to end on Monday 7 February instead of Friday 4 February. The total amount of money won during the week was $173,000. The highest amount of money won was $80,000 when first, a contestant had the $50, "Fantastic" $100,000 and $200,000 left and was offered $75,000. The contestant played on and lost the "Fantastic" $100,000 and was offered $80,000. He dealed and his case contained $50. Another contestant also had the $50,000 in their case, but chose to deal earlier.

On 11- 15 April 2011, a series of Fiji Fantastic Four specials aired. The total amount of money won during the week was $167,700. Amazingly, one contestant had the "Fantastic" $100,000 and $75,000 amounts, and the regular $50,000 and $1 in play. The contestant continued playing and lost both "Fantastic" amounts in the next two rounds consecutively. He was offered $21,000 and said no deal, and won $50,000.

On 21-25 November 2011, a series of Hawaiian Fantastic Four specials aired. The total amount of money won so far is $15,000.

After the first series of Fantastic Four specials in 2009, individual specials now randomly air throughout the year. The total amount of money won over the 37 specials that have aired so far is $914,401. The highest amount of money won by one person is $100,000, which is the first time that a "Fantastic" amount was selected. The "Fantastic" $75,000 and "Fantastic $50,000" have also been selected once. For the first special of 2010, the $250,000 top prize was changed back to $200,000. From the second special of that year onwards, the regular $200,000 case design was used instead of the gold background used for the "Fantastic" amounts.
