Yugi wonders what kind of traps Kaiba has in store for them inside . Yugi feels something vibrating in his pocket . He pulls out his grandfather ' s cards and is astonished to find he can feel a heartbeat through the cards . His friends gather around and ask if something is wrong . The cards are telling him that his grandfather is in critical condition , he tells his friends . His friends look at him in shock and ask what he means , apart from Johji , who lies carefree in Anzu ' s arms , picking his nose . Yugi recalls his grandfather saying that his soul was in these cards and vows to defeat Kaiba with the Heart of the Cards . Jonouchi reminds the group that they cannot afford to wait around and insists that they get going . If what Yugi said about his grandfather is true , they must clear this stage quickly , Honda announces and kicks open the door to the mansion . The group find themselves in a musty unlit old fashioned room . Anzu suggests that they stay still until their eyes adjust . The doors suddenly slam shut behind them . Anzu quickly checks them and finds that they are locked in . Jonouchi tries rattling at the doors after her and asks if anyone has a wire , so he can pick the lock . Anzu looks at him abashedly , commenting that he has some strange talents . Johji yells at Jonouchi in degradation , asking why he ' s trying to open the door they came in . He calls him a dummy and says that they must find the exit . Honda agrees and the group split up to find a way out . While everyone searches around , Yugi finds a sheet of paper attached to a suit of armor . " Blood " , seemingly misspelled as " Bllood " is written on the paper . The second l is also an arrow pointing downwards . Yugi wonders what it means , and interprets it as a bad omen . Jonouchi reports that there is no way out . Honda goes upstairs to check for an exit , but finds that the ceiling blocks him going any further at the top of the stairs . A projection of Kaiba appears and welcomes the group to the Murderer ' s Mansion . Jonouchi is surprised to see Kaiba floating midair , but Yugi informs him that it is just a hologram . Kaiba observes that they are searching for an exit and warns them that something bad will happen if they do not escape soon . Kaiba prepares to explain why the place is called the Murderer ' s Mansion , asking the group if they remember what happened last summer at the camp near Domino Lake ; terrible murders which had all of Domino City cowering in fear . Ten boy scouts , who had been staying at the camp were murdered in one night . Kaiba describes the brutal nature of the deaths , saying that not even a master of puzzles would have been able to assemble the body parts back into human form , as mince meat had been made of the boys . The suspect of the crime came to be known as " The Chopman " and he is still at large , Kaiba informs them . The group look up in fear at Kaiba , who smirks that they have already guessed it ; the Chopman is hidden in the mansion . Cruelty is considered an asset at KaibaCorp , so they scouted the Chopman to manage this attraction , in the theme park of death , he laughs and asks if they will be able to escape the mansion without running into the Chopman . To make it fair , Kaiba says that he will give them a hint to help find their way out . He directs them to the wall behind them , which contains four holes , labeled 00 , 01 , 10 and 11 . There are switches on the other side of the wall . If they press the right one , the location of the exit will be revealed . Yugi is certain that this is a trap , but with no other option , he , Jonouchi , Honda and Anzu put their hands inside the holes . Locks are suddenly cuffed onto their hands , preventing them from pulling their hands back out . The group then notice a giant guillotine overhead . Kaiba laughs and announces the start of the game . He explains that one of the switches is real , the others will cause the blade to drop and slice off their hands . He gives them five minutes to find the right switch , before the blade drops itself . They can only press one switch , he tells them . As the hologram fizzles , Kaiba says that he has left them a hint hidden in the room . He wishes them luck and the hologam vanishes . The friends are left struggling to figure out which is the correct button . Yugi wonders what the numbers could mean . They are all ones and zeroes , Anzu notes , like , whose name escapes her . Jonouchi starts to lose his cool . Honda recalls that Kaiba had told them that there was a hint hidden in the room . Yugi remembers the slip of paper and takes it out , thinking it could be the hint . He shows it to the others . Honda curses . He hates games involving numbers and letters . Anzu assures Yugi he can solve , since he managed to solve the Millennium Puzzle . Johji looks at them unperturbed , picking his nose . Yugi focuses on the double L in the word , thinking the answer must be to do with the misspelling . Honda alerts him that they have only two minutes left . Yugi concentrates and Johji yawns . With only one minute left , Jonouchi hurries Yugi up . Yugi starts to doubt himself and asks why Kaiba did this . He then remembers that his grandfather is waiting for him . Honda yells that there is no more time . Yugi vows to save everyone . Time runs out and the blade starts to move . The answer suddenly hits Yugi and he tells Anzu to press her button . Anzu complies and the blade stops , much to everyone ' s relief . The cuffs are unlocked , releasing everyone ' s hands . Yugi breathes a huge sigh of relief and Anzu asks how he got the answer . At first he kept thinking about the meaning of the word " blood " , Yugi explains , but the shape of the letters was what was important . The word was made up of ones and zeroes ; " bllood " could be looked at as " 10 11 00 01 " . The second L was also an arrow pointing down , so the exit must be in the basement . The right answer was the eleven , which had the arrow in it and corresponded to Anzu ' s switch . The floorboards behind Johji , fold away on hinges , revealing a hidden trapdoor . The others celebrate that they now have a way out , while Johji calls to the ordeal boring . Unbeknownst to Johji , the trapdoor opens behind him . Inside is a figure with glowing eyes and crooked teeth . Appearances . Debuts are in bold . Anime adaption . Episode 23 of the Toei anime , , is based on a portion of the manga ' s Death - T arc , including this chapter . A number of differences were made , including :
