Yu - Gi - Oh ! Duel Arena Yu - Gi - Oh ! Duel Arena was an official online " Yu - Gi - Oh ! Trading Card Game " simulator . It had an automatic Duel system , allowing users to Duel opponents through the internet . The cards used in the simulator were periodically updated to match the latest cards appearing in the " Trading Card Game " . The Open Beta version of this game opened on May 30th , 2014 . Any user data gained during the Open Beta version would not be transferred to the commercial version of the game when it opened . The Open Beta ended on June 19th details to the full release were announced . The official version was released on June 26th , 2014 . On January 28 , 2015 , it was announced the game would go offline , which it did on March 27 , 2015 . Partners . In " Yu - Gi - Oh ! Duel Arena " , the game offers Partners as a way of accommodating new players who lack the skills and / or cards to build viable Decks , as well as offering these Partners as a form of personal customization . Partners consist of a mixture of monsters and characters , with each Partner having a unique Partner Deck . Whenever a player acquires a new Partner , they permanently gain the ability to rent its Partner Deck . Players can also set any of their Partners as their Leader , which serves as the player ' s avatar image in - game and represents the player in the Virtual Arena . Players can only set 1 Partner as their Leader at any given time . Partner Decks . By " renting " a Partner Deck for a Duel / Match , a player is allowed to use the entirety of that Deck ( Main Deck , Extra Deck , and Side Deck combined ) for that specific Duel / Match . However , because players do not actually " own " the cards that the Partner Decks contain , they can neither modify the Partner Deck ' s contents nor use any of that Deck ' s cards for other purposes ( i . e . using them in other Decks , or attempting to convert them into DP ) . Each time a player Duels with a Partner Deck , this will use up 1 Rental Point for that Deck , even if either player gets disconnected or surrenders . The number of Rental Points a Partner initially has is determined by its Rarity . Normal Partners start with 3 Rental Points , Rare Partners with 4 Rental Points , Super Rare Partners with 5 Rental Points , and Legend Rare Partners with 6 Rental Points . When a Partner ' s Rental Points are used up , the player cannot use its Partner Deck until they refill its Rental Points . When a Partner Deck ' s Rental Points run out after a player wins , loses ( including surrenders ) , or ties a Duel / Match , that player is immediately offered the option of renewing those Rental Points to their default maximum . Doing so costs 1000 DP . If a player declines , or was disconnected , they can renew them again at any later point . Rental Points can alternatively be restored by obtaining another copy of that Partner . When this is done , the Rental Points are simultaneously refreshed ( if depleted by any amount ) and have their maximum amount increased by 1 . All Partners can potentially have a maximum of 8 Rental Points this way . If a player obtains a Partner again that already has 8 unused Rental Points , they will receive a message from Dark Magician Girl stating , " I ’ m so sorry . . . It looks like this partner has maxed out it ’ s Rental Points and is fully recovered . " Partner Recruiting . All players automatically receive Yugi Muto as a partner when they enter " Duel Arena " for the first time . Additional Partners can be obtained through Partner Recruiting , special in - game events , and the first stage of Quests . There are two types of Partner Recruiting : Normal and Premium . Once per day , the first time each player uses Normal Partner Recruiting , it is accomplished for free . Additional uses of Normal Partner Recruiting during the same day costs 2000 DP each time . Premium Partner Recruiting costs 1000 Miniclip Credits each time , but guarantees the player a Partner that is classified as Rare or higher . The Partners received this way are random , and any Partner can be obtained through either method of Partner Recruiting , except for the ones that are Quest - exclusive and promotion / event - exclusive . Dueling . There are many ways to conduct a Duel in " Yu - Gi - Oh ! Duel Arena " . However in order to Duel , a player must meet three conditions : Each time a player Duels , this will consume 100 Stamina , even if either player gets disconnected or surrenders . Each player ' s Stamina refreshes by 1 unit every 3 minutes , disregarding their online status , to a maximum of 500 Stamina . If a player has 99 or less Stamina , 500 Stamina can be instantly restored by spending 1000 Miniclip Credits , or by using an Energy Drink ( awarded from various promotions / achievements in - game ) . This can temporarily increase a player ' s Stamina above the 500 unit threshold , but they will not gain additional stamina until it drops below 500 again . Players have 300 seconds to think and make their moves during each turn in a Duel , with a 10 second delay after each action . If a player runs out of time , they immediately lose the Duel / Match . If a player wins a Duel , they earn 200 DP . If they lose a Duel ( without surrendering or disconnecting ) , they earn 100 DP instead . After completing a Match , the players receive these same rewards , but accumulate them based on the victories / losses they endured for each Duel in that Match . Upon completing their first Duel / Match each day , players receive a 1000 DP bonus , in addition to any other rewards they earned from that Duel / Match . Single Play . Duels in Single Play are conducted between a player and an AI opponent . Only " Single Round " Duels can be done in Single Play . Quest Mode . In this mode , the player can play against pre - determined AI opponents . Each individual Duel in this mode is called a " Quest . " As the player progresses through Stages , the opponents readily become more difficult . In order to progress to the next Stage of Quests , a player must complete all 5 Normal Quests on their highest unlocked Stage ( in any order ) by winning those Duels , which will unlock the Boss Quest for that Stage . Until this occurs , the Boss will remain silhouetted . Once the player completes the Boss Quest by winning their Duel , the next Stage is unlocked . Upon clearing a Boss Quest for the first time , the player will receive an Energy Drink , and either 1000 DP or a total of 500 DP x the Stage level of the Boss Quest ( whichever is higher ) . When a new Stage of Quests is released in - game , these rewards are temporarily doubled for that Stage until the next in - game maintenance ( usually 7 days later ) . Any Quest in any Stage can be played again to potentially earn the Single Play DP reward . " For the list of Quests , see List of Yu - Gi - Oh ! Duel Arena Quests . " Virtual Arena . In the Virtual Arena , the player can Duel other players ' Leaders ( specifically chosen Partners ) that are controlled by an AI . This can be done with any Deck that complies with the current Forbidden & Limited Card List for " Yu - Gi - Oh ! Duel Arena " . Unless the player chooses a specific Leader Deck for their own Leader , that Leader will use its own Partner Deck in Duels when it defends itself against other challenging players in the Virtual Arena . Even if the defending player is online when their Leader is defending itself , their Leader will be controlled by an AI . If a Leader is paired with a Deck that does not comply with the current in - game Forbidden & Limited Card List , it will not appear as an opponent in the Virtual Arena . The normal Single Play DP rewards apply for challenging a Leader in the Virtual Arena , but the player whom the defending Leader represents will only earn 50 DP from that Duel , regardless of victory or loss . This occurs even if the defending player is offline . At one point , a variant of Virtual Arena mode was introduced in the form of Duel Monsters Arena , which coexisted with the regular Virtual Arena from October 22 , 2014 through November 5 , 2014 . Arena . Dueling in the Arena allows the player to Duel other random live players through single Duels and Matches . If one of the players disconnects ( regardless of intention ) or surrenders , the remaining player is given 30 seconds to decide whether or not they want to continue the Duel / Match . If the player accepts , the Duel will carry on from the same moment their opponent left the Duel , except with an AI representing the opponent with the Deck they were using . The standard DP rewards will apply as well . However , if the player declines , their Stamina will be refunded and the Duel / Match will not be recorded in their Duel History . If a player disconnects , they will not earn any DP , and will also receive a warning regardless of their intentions . If a player does this twice within sixty minutes , they will be barred from being logged into " Yu - Gi - Oh ! Duel Arena " until four hours have passed since their most recent disconnection . If a player surrenders their Duel , they will not earn any DP , but they will not receive a warning either . Players also earn an additional accumulative reward for each Duel they complete in the Arena each day , starting with 50 DP . For each additional Duel completed during the same day , their bonus reward increases by 50 , to a maximum of 500 DP ( which they can continue to earn from subsequent Arena Duels for the rest of that day ) . However , this bonus reward resets at the beginning of each day ( 0 : 00 GMT ) . Duel with Friend . Players can also Duel people in their Friend List , by sending them a Duel / Match request if they are online and not Dueling . To send the request , the player must navigate their way to a specific friend ' s profile page and clicking the " Invite for Duel with Friend " button , where they will be prompted to choose to engage in either a Single Duel or a Match , as well as providing a brief message . Once the request is sent , the initiating player is taken to a loading screen while they wait for their opponent to join . In the meantime , the opponent is immediately informed about the request through their " Duel with Friend Notification Bar " flashing yellow and a repetitive alert sound ( which can have its volume adjusted ) . To accept the Duel , the opponent can click on the bar , where they will be subsequently redirected to their " My Friends " page . The opponent must then find their friend , which will redirect them to their friend ' s profile page . At this point , the opponent can change their mind and decline the request on their friend ' s profile page , or choose to accept the request . Both players are then led to the standard Deck selection screen . If their opponent has not yet joined , the initiating player can end the request at any time by clicking " Cancel " on the loading screen . Alternatively , their opponent can also decline the Duel request by attempting to engage in a different Duel , where they will be prompted that doing so will reject their friend ' s Duel request . Players can avoid potential friend Duel requests in the first place by setting their Login info to " Private . " Standard penalties for disconnecting are applied after both players have joined . Neither player earns any reward from friend Duels , and must also have at least 100 Stamina to spend in initiating or accepting a friend Duel . If there is a promotion in - game that waives Stamina usage for friend Duels , players must still have at least 100 Stamina minimum to engage in such a Duel . ( Duel Initiation ) . Once both players have been paired with each other , a Deck selection screen appears , where players can choose to use a Partner Deck ( if it has any remaining Rental Points ) , one of their potential 20 custom Decks , or a quick - select of their designated " Favorite Decks " ( which can include a total of 3 Partner and / or custom Decks ) . Both players have 60 seconds to decide . After a player has selected their Deck , they are taken to a " Rock - Paper - Scissors " screen , which both players will use to decide who goes first . In a Match , after one of the Duels has been concluded with no definitive winner for the Match yet , both players will be taken to a Siding Screen . During the subsequent 180 seconds , either player can take the time to swap cards from their Main Deck and / or Extra Deck with their Side Deck . Once they are done , they can click on " Swap Done " to be taken to the next loading screen , where the loser of the previous Duel chooses whether or not to go first . Regardless , once 180 seconds have passed , both players are forcibly taken to that screen ; if one or both players did not click " Swap Done " , that player ( s ) will use the same Main Deck and Extra Deck they used in the previous Duel , regardless of any changes they managed to make during siding . In - Game Currency . Duel Points ( DP ) are the most common form of currency in - game . They can be obtained by completing Duels without surrendering or disconnecting ( except friend Duels ) , by defeating a Boss Quest for the first time , sending / receiving Greetings , or by converting one ' s own cards into DP . The conversion rate is 1 card for 50 DP , regardless of the card ' s rarity . DP can be used to buy or use the following : A player can only have a maximum of 99 , 999 DP at any given time . Miniclip Credits ( MC ) serve as a secondary form of currency in - game . They are points that cost real money , which can be shared over multiple Miniclip games , and can be used to buy certain in - game content . The cost of Miniclip Credits varies depending on the quantity they are bought in , becoming less expensive per Credit as more are bought in one single purchase . Miniclip Credits can be used to buy or use the following : In the beta , Coins served as the interim substitute for Miniclip Credits , with equal value . However , these were free and allocated in amounts of 10 , 000 Coins upon completion of a player ' s first completed Duel per day ( without surrendering or disconnecting ) . This amount was later increased to 50 , 000 Coins after the announcement declaring that the beta was closing . These Coins could not be used in other Miniclip games . Friends . By being " friends " with another player in - game , this allows the player to exchange " mail " and " greetings " with them , as well as initiate or receive " Duel with Friend " requests . To become " friends " with another player in - game , one of two methods involves the player accessing the potential friend ' s profile page and selecting the " Friend Request " button , where they must wait for the recipient to read their request mail and select the " Add as Friend " option , which will automatically send back an acceptance mail to the original sender . To cancel the request , the player can visit the recipient ' s profile page to withdraw it . The recipient can alternatively select the " Don ' t Add as Friend " option in the mail they receive . To avoid receiving friend requests , the player can set their profile information to " Private " , which hides the " Add as Friend " button on their profile . The second method requires both players to input each other ' s Duelist Code via the " Verify Duelist Code " feature . Alternative means outside the game are required in order to exchange Duelist Codes , as each player ' s Duelist Code on their profile page cannot be seen by other players . Players will not be notified if another player inputs their Duelist Code via the " Verify Duelist Code " feature . If a player changes their name during this process of making friends , this will change their Duelist Code , requiring a restart of the process in order to become friends . To cancel the process , the player who inputted the Duelist Code can go to their " My Friends " list and navigate to the inputted Duelist Code to withdraw it . Players can only have a maximum total of 100 friends and / or pending Friend Requests that were sent , at any given time . Once a player accepts their 100th friend , all pending Friend Requests that they have received will become invalid , and will not become valid again even if the player has less than 100 friends at some later point . If a player wishes to add additional friends , they must navigate to at least one of their current friends ' profile pages and select the " Unfriend " button , which will allow both players to send / receive friend requests again . However , the " unfriended " friend will not be notified of this process . Having friends is encouraged in - game , as " friends " can send each other greetings ( with a 30 - character limit ) , which earns the sender and recipient 10 DP ( each ) by doing so . If a player sends greetings to all their friends , and all of those friends send greetings to them in return , a maximum of 200 DP can be earned daily by this method .
