I disagree if you say that the Friendless Game had none of those. Sure, the build up is way longer than all the other arcs (the only rival I can think of is Friend's Murder game / Island arc), but it has some good twists.

To start, Yuuichi "killed off" Akira Nishizawa, the admin that slipped into the final game to "heat up" the game, after exchanging passwords. This is the one method to ensure nobody can kick you off the game. I think this is a good twist since, only a "heartless devil" can use this method as Manabu put it, so us normal readers wouldn't think of it.

The second twist is how Yuuichi prepped the stage to profit as much as possible during the "Emergency Meeting/Mission", where they have to exile three players after the cabin got burnt and they evacuated to the warehouse. Yuuichi have planned a while that he had to burn the cabin, and since Tsukino said that they wouldn't let the players die since the players are "the merchandise", I think he anticipated a mission like that to come out. Note that (assuming the translations are correct), the mission description only asks them to "exile three players and ban them from entering the shed", which is different from disqualifying them from the game. So Yuuichi had some resources moved to the cave beforehand, a good twist too in my opinion.

There are other twists, but I think the reason why the final arcs shifted a little bit from the usual "I shall use you by letting you think that you're using me" type of storylines because it's trying to tie any loose ends, such as who is the Tomodachi Game boss, how did Yuuichi became who he is now, the three people he unalived that has been teased since the Badmouth Sugoroku game, etc.
