=第一階級=
【基礎】有本地麻雀基礎

【目標】達到能參與遊戲的程度
==食替==
日麻通常不允許【食替】，【不允許食替】就是不能用吃碰換張

* 用[[File:2p.png|27x39px|alt=2p]][[File:3p.png|27x39px|alt=3p]]去吃時，不能立刻打[[File:1p.png|27x39px|alt=1p]][[File:4p.png|27x39px|alt=4p]]，要過一輪才能打

* 用[[File:1p.png|27x39px|alt=1p]][[File:3p.png|27x39px|alt=3p]]去吃時，不能立刻打[[File:2p.png|27x39px|alt=2p]]，要過一輪才能打

* 用[[File:2p.png|27x39px|alt=2p]][[File:2p.png|27x39px|alt=2p]]去碰時，不能立刻打[[File:2p.png|27x39px|alt=2p]]，要過一輪才能打

==振聽==
以下3種情況進入振聽，振聽=只能自摸
===捨牌振聽===
聽的牌被自己打過（永久）

【例】[[File:2p.png|27x39px|alt=2p]][[File:2p.png|27x39px|alt=2p]][[File:2p.png|27x39px|alt=2p]][[File:3p.png|27x39px|alt=3p]][[File:4p.png|27x39px|alt=4p]][[File:5p.png|27x39px|alt=5p]][[File:5m.png|27x39px|alt=5m]][[File:6m.png|27x39px|alt=6m]][[File:7m.png|27x39px|alt=7m]][[File:3s.png|27x39px|alt=3s]][[File:3s.png|27x39px|alt=3s]][[File:3s.png|27x39px|alt=3s]][[File:4s.png|27x39px|alt=4s]]聽[[File:2s.png|27x39px|alt=2s]][[File:4s.png|27x39px|alt=4s]][[File:5s.png|27x39px|alt=5s]]（[[File:2s.png|27x39px|alt=2s]][[File:4s.png|27x39px|alt=4s]][[File:5s.png|27x39px|alt=5s]]任意一張打過就【振聽】）

===立直振聽===
[[立直]]後:聽的牌被打出，但不[[和牌]]則[[振聽]]（永久）

===同巡振聽===
聽的牌被打出，但不[[和牌]]，則[[振聽]]（之後打出1張牌就解除振聽）

（例[[File:3m.png|27x39px|alt=3m]][[File:4m.png|27x39px|alt=4m]][[File:5m.png|27x39px|alt=5m]][[File:6m.png|27x39px|alt=6m]][[File:7m.png|27x39px|alt=7m]][[File:8m.png|27x39px|alt=8m]][[File:7p.png|27x39px|alt=7p]][[File:7p.png|27x39px|alt=7p]][[File:2s.png|27x39px|alt=2s]][[File:3s.png|27x39px|alt=3s]]　[[File:4p.png|27x39px|alt=4p]][[File:4p.png|27x39px|alt=4p]][[File:h4p.png|36x30px|alt=橫4p]]聽[[File:1s.png|27x39px|alt=1s]][[File:4s.png|27x39px|alt=4s]]，和[[File:4s.png|27x39px|alt=4s]]有【斷么】役，和[[File:1s.png|27x39px|alt=1s]]是0翻。
有人打了[[File:1s.png|27x39px|alt=1s]]，0翻不許和，會強行進入同巡振聽，同巡內，別人打的[[File:4s.png|27x39px|alt=4s]]沒法和）

==役==
【役】日本麻雀必須滿足【一定的條件】才能和牌，這些條件就是【役】
[[懸賞牌]]不是役

日麻役雖然多，但是絕大部分可以暫不記

# 門前清只要立直就能和，需要【門前清（沒有吃、碰、明杠）】的可以暫不記
# 太難的役（比如役滿）

==點數的初步知識==

* 親家（最先出牌的人）和牌時，收益是其他人（子家）的1.5倍 
* A給B放炮（放銃）時，A一個人支付全部點數
* 子家自摸時，親支付點數的一半，其他子家支付四分之一 
* 親家自摸時，每個子家支付三分之一 
* 每個【本場】需要多出300點（2本場時，和2000點，會變成2600）

5翻以下才會用到【符】，下表顯示了分數與翻數的大致的規律（實際比表上少一點）

==懸賞牌==
（又稱寶牌，DORA）
每有1張懸賞牌就多1翻，[[懸賞牌]]可以疊加計算（也就是1張牌可能變成2翻）

牌山默認會翻開一張[[表懸賞表示牌]]，這張牌的下一張便是[[懸賞牌]]

紅色的[[File:0m.png|27x39px|alt=0m]][[File:0p.png|27x39px|alt=0p]][[File:0s.png|27x39px|alt=0s]]也是懸賞牌（赤懸賞牌）

* 即使有懸賞牌，沒有役，無法和牌。
* 有杠發生時，【懸賞表示牌】右側的牌翻開，作用和懸賞表示牌相同
* 立直和牌後，所有【懸賞表示牌】下方的牌翻開，作用相同
* 懸賞牌規律如下，日本麻雀字牌的順序是【東南西北白發中】

全莊比較長，一般打半莊戰（東1局~南4局）

===連莊===
莊家和牌、流局時聽牌會繼續坐莊家。否則下莊（輪莊）

===輪莊===
莊家連莊失敗時，上局的南家變成莊家，這稱為輪莊

===本場===
只要[[流局]]，或是[[親家]]和牌，本場都會加1，例如【東3局，2本場】

在和牌的時候，每個本場額外獲得300點

==流局==
'''流局'''（又称'''荒牌'''），术语的一种，是除了和牌以外牌局的结束。

流局分 荒牌平局 和 途中流局
===荒牌平局===
当牌山剩下14张，而沒人和牌稱為流局（荒牌平局）
是否連莊：看親家是否聽牌

===途中流局===
分以下幾種，一般會連莊：

====九種九牌====
第一次出牌時，手牌的幺九牌9種以上
* 此前没有人吃、碰、明杠、暗杠、拔北
* 可選擇不流局

====四風連打====
四家最初打的是同一張風牌(即：{1234z})
* 中途没有人吃、碰、明杠、暗杠、拔北

====四杠散了====
四家共計杠四次
* 同1人開4杠不流局

====三家和了====
有人同時放銃給其他三家
* 和牌方有親家則連莊

====四家立直====
四家立直
* 第四家立直时不能[[放铳]]

===不聽罰符===
荒牌流局時，沒有流局滿貫的情況下，沒聽牌的人要支付【不聽罰符】

===筋===
見:[[筋]]

===壁===
壁作用：【例】當[[File:3p.png|27x39px|alt=3p]]在你可以看到的任何地方（[[手牌]]，[[懸賞表示牌]]，[[牌河]]，[[副露]]）合計出現4張的時候，與[[File:3p.png|27x39px|alt=3p]]有關的[[File:2p.png|27x39px|alt=2p]][[File:3p.png|27x39px|alt=3p]]和[[File:3p.png|27x39px|alt=3p]][[File:4p.png|27x39px|alt=4p]]不可能存在。則[[File:3p.png|27x39px|alt=3p]]外側的[[File:1p.png|27x39px|alt=1p]][[File:2p.png|27x39px|alt=2p]]安全度等同於字牌（只[[放銃]][[雙碰]]和[[單騎]]）

即：
* [[File:2p.png|27x39px|alt=2p]]成壁，[[File:1p.png|27x39px|alt=1p]]安全
* [[File:3p.png|27x39px|alt=3p]]成壁，[[File:1p.png|27x39px|alt=1p]][[File:2p.png|27x39px|alt=2p]]安全
* [[File:7p.png|27x39px|alt=7p]]成壁，[[File:8p.png|27x39px|alt=8p]][[File:9p.png|27x39px|alt=9p]]安全
* [[File:8p.png|27x39px|alt=8p]]成壁，[[File:9p.png|27x39px|alt=9p]]安全

====雙壁====
當然也有雙壁的情況：

* [[File:1p.png|27x39px|alt=1p]][[File:4p.png|27x39px|alt=4p]]成壁，[[File:2p.png|27x39px|alt=2p]][[File:3p.png|27x39px|alt=3p]]安全
* [[File:3p.png|27x39px|alt=3p]][[File:6p.png|27x39px|alt=6p]]成壁，[[File:4p.png|27x39px|alt=4p]][[File:5p.png|27x39px|alt=5p]]安全

====薄壁====
成爲壁的不是4張，而是3張
薄壁安全很低
