Yakuza Kiwami 2

I have a few tips for Mahjong, which is the thing that will likely give people the most difficulty on the completion list. If you have previously completed Yakuza 0 or Kiwami, then you probably already know how to play Mahjong. If not, here is a basic guide to Japanese Mahjong: https://yakuza.fandom.com/wiki/Mahjong. There is also a more advanced guide here: http://uspml.com/documents/japanese_mahjong_guide_v103.pdf (credit to Barticle for both guides). The Mahjong related completion list requirements are as follows:

Win all Mahjong tables and tournaments
Go out with Ron or Tsumo 30 times
Earn 100,000 points in Mahjong.


Assuming you are familiar with the basic gameplay of Japanese/Riichi Mahjong, here is the strategy I used to get the 30 Ron or Tsumo requirement. In your starting tiles, keep any melds or pairs that are already in your hand. Your goal is to make 4 melds and one pair. A meld consists of 3 tiles from a suit in sequence (example: 456 bamboo) or 3 of the exact same tile. A pair is simply 2 of the same tile. Two of the easiest hands to go for as a beginner are Pinfu (No Points Hand) or All Simples. Pinfu is a hand that consists of only suit tiles (not honour tiles). An example Pinfu hand would be 234 of bamboo, 678 of dots, 123 of characters, 456 of terminals and 55 of dots. All Simples is a hand that contains only suit tiles of number 2-8. I often discard suit tiles that are numbered 1 or 9 just so I can go for All Simples. I also usually discard all honour tiles (the 4 dragon tiles and 3 wind tiles) early in the round, unless I have a triplet or pair of them in my starting hand. They are less versatile and harder to form hands with than the suit tiles. There are other more complicated elements of Mahjong such as prevailing wind, round wind, dora and ura-dora, but you don't need to worry about these too much if you are just doing the completion requirements.

As a round progresses, you will have the option to press X to call Riichi. You should press X on every turn so you don't miss any opportunity to call it. As far as I'm aware, you have to press X for the prompt to appear. Riichi is a situation where you are one tile away from forming a complete hand. For the most part, you should be looking to call Riichi whenever the opportunity presents itself. There are niche situations where not calling Riichi is correct, but this is a high-level strategy that isn't important for new players. After calling Riichi, you can win by Ron (steal another player's discarded tile) or Tsumo (win with a tile you draw yourself). You can also win with Ron or Tsumo without calling Riichi, but the majority of your wins will most likely be from calling Riichi then doing Ron or Tsumo. For me it took around 5 hours to get the 30 Tsumo/Ron requirement finished. There is a substantial element of luck in Mahjong relating to which tiles are in your starting hand. It can be hard to win if you start with a bunch of tiles that are discombobulated.

Getting a win on each table is self-explanatory. There is an Easy and Medium table in Sotenbori, and a Medium and Hard table in Kamorucho. You need to win a match on each table. For the tournaments, I highly recommend using Peerless Tiles for both of them. Peerless Tiles are the cheat item for Mahjong. There are 3 available per playthrough. One is obtained from completing Substory 31, the other two are hidden items. There is one hidden on the third floor of Lullaby Mahjong in Kamorucho, the other one is in Yotsudera Kaikan in southwest Sotenbori. There is one tournament in Kamurocho and one in Sotenbori. You must first complete games at the normal tables before you can enter the tournaments. The 100,000 points requirement should unlock naturally just through going for the other requirements, but if it doesn't, just keep playing at the Easy table until you reach 100,000 points.

Most of the other minigames are fairly straightforward. There are a few that gave me some trouble until I discovered a good strategy for them. For Milky Nose (aka the pissing minigame), drink 1 Iyemon Tokucha Green Tea and 2 Vitamin C drinks. This will give you a 1600ml bladder capacity. To win the minigame, you must use LT and RT to match the AI player's power. Then when the gauge on the right is full you hold RT to knock them out with your piss stream.

There is a request from Haruka where you need to win 3 matches in a row in Virtual On. The first two AI opponents are easy, but the third gave me a lot of trouble. I used the 3rd character from the left. I don't know actual name of it. It has an LT attack that fires a homing projectile and an RT that fires a beam gun. I mostly used LT from a distance while dodging with X and Y as much as possible. It took me quite a few tries. If anyone knows a better strategy, let me know.
