Various design choices had been made to make sure that some murders would actually happen at the end of the larp. There was a whole group of poor characters determined to kill some rich people. They had already murdered somebody in the backstory, and they were determined to kill more people during the larp. [[Massi Hannula]] had come up with the idea of an in-game radio channel called ''Murharadio'' (Eng. ''Murder Radio''), that was run during the larp by a group of poor characters. On the radio shows, they had angry discussions on inequality, interviewed murderers, and speculated on who should be murdered next. They also held a poetry competition, where listeners were asked to send them "murder poems" through social media.
''Tuhannen viillon kuolema'' used the social media platform ''Kin'' for in-game social media. Players were very active on it during the larp. The rich and the poor were involved in flame wars about social inequality, and some characters and NPCs used the social media platform tp to incite violence. Meanwhile, the middle class characters were posting pictures of their after work drinks and composing carefully worded descriptions of their pastimes to make their lives look more glamorous and to hide the fact that they were unsatisfied with work and on the verge of burnout.
The rules of the larp stated that only rich characters could get murdered, and only poor characters could murder others. Rich characters were wearing small badges so that others would recognise them. Murders were not allowed before the last hours of the larp. They were acted out by theatrically stabbing the other person without a knife prop. The larp also used a "richsplaining" mechanic to portray class privilege: when a rich character held the palm of their hand up in a rejecting gesture while speaking, the poor characters could not speak, unless they physically touched the rich character. According to [[Kaisa Kangas]] who invented the mechanic, the idea was that in order to have their voice heard, a poor character would have to cross the boundary of touching the other person (which is a clear transgression in Finland where the larp was run), which could lead to escalation<ref>Kangas, K.: "Class Privilege and Conflict Escalation".
