You seem to really be into it.

If I had to explain it, I guess I feel like I'm on top of the world.

Is, is that right? By the way, why are you carrying that nail bat?

Ah~ this?

I had to give some punishment to a wicked boob girl.

I, I see.

Make sure you don't become evil too, Saki-chan.

Ye, yeah...

This time is individual yaku explanations, part 1. Saki-chan, take it away!

Eh? Ah, sure

Umm, first let's introduce "riichi". Riichi doesn't have to do with special combinations; if you're menzen and tenpai, you can declare riichi, and it's a yaku worth 1 han. You just need to be menzen and tenpai, and it can combine with any yaku. You cannot declare riichi at any point after fuuro or if, despite being menzen and tenpai, there aren't enough tiles left for you to draw next turn. Also, if you declare riichi on the first turn, it becomes "double riichi". For both riichi and double riichi, you turn the tile you discard on the turn you declared it sideways and put a 1000 point stick in the middle.

Basically, riichi is a yaku you can buy for 1000 points!

Tenpai by discarding 9-pin or 6-pin
