* '''[[Dora]]''' | * '''[[Dora]]''': After the walls are built, and hands are drawn, one tile in the dead wall is turned face up. This tile is a ''dora'' indicator; the tile that is '''next''' sequentially is a ''dora'' tile. For numeric tiles, the sequence goes in order from 1 to 9, with 9 indicating 1 as ''dora''. For dragons, the order is White --> Green --> Red --> White, and for winds, the order is East --> South --> West --> North --> East. If a winning hand contains a ''dora'' tile, it earns 1 ''han'' for each such tile as a bonus. So, for example, if the ''dora'' indicator is a 3 of bamboo, then a winning hand that contains two copies of a 4 of bamboo will earn an additional 2 ''han'' on top of what it would earn from ''yaku'' / scoring patterns. The 3 of bamboo is still a normal tile. | ||
** '''Kandora''' | ** Note that ''dora'' do not in and of themselves count as ''yaku''. In the full Japanese Mahjong ruleset, with a 1-''han'' requirement to win, a hand must have at least one ''yaku'' to qualify -- ''dora'' are not enough! (This fact is another reason why ''Riichi'' is a very valuable ''yaku'' to understand!) | ||
** '''Uradora''' | ** '''Kandora''': A common rule is that, when a ''kan'' is declared, another tile in the dead wall is turned face up to act as another ''dora'' indicator. | ||
** '''Uradora''' (Under ''dora''): If a player wins with the ''Riichi'' ''yaku'', then they have the privilege to also look at the tile underneath the ''dora'' indicator, and use that as an additional bonus ''dora'' indicator. If any ''kan'' has exposed additional ''dora'' indicators, then the winning player can look under those ''dora'' indicators as an even larger bonus chance! | |||

** '''Closed-only scoring patterns''': Fully Concealed Hand (''[[menzen tsumo]]''), [[Pinfu]], Two Identical Sequences (''[[iipeikou]]''). Most of the time, if your hand reaches ''tenpai'' without making any calls, you're probably going to want to call ''riichi''. So you might think of these patterns are bonuses to your hand's value when it is won with ''riichi''. | ** '''Closed-only scoring patterns''': Fully Concealed Hand (''[[menzen tsumo]]''), [[Pinfu]], Two Identical Sequences (''[[iipeikou]]'').

** '''Uncommon patterns''': Full Straight (''[[ikkitsuukan]]''), Three Similar Sequences (''[[sanshoku doujun]]''), Included Terminals and Honors (''[[chanta]]''), Included Terminals (''[[junchan]]''), Seven Unique Pairs (''[[chiitoitsu]]''). Identifying opportunities for these ''yaku'' is trickier than the bread-and-butter patterns that were introduced at first. However, their higher ''han'' values can make them valuable when those opportunities show up. Note that many of these patterns are worth fewer ''han'' if they are in a hand with open calls. (Such is also the case for the Half Flush and Full Flush hands.) | ** '''Uncommon patterns''': Full Straight (''[[ikkitsuukan]]''), Three Similar Sequences (''[[sanshoku doujun]]''), Included Terminals and Honors (''[[chanta]]''), Included Terminals (''[[junchan]]''), Seven Unique Pairs (''[[chiitoitsu]]'').

* '''Scoring in Riichi Mahjong''': In the actual scoring of Japanese Mahjong, points are measured in the hundreds and thousands instead of ones and tens. | * '''Scoring in Riichi Mahjong''': In the actual scoring of Japanese Mahjong, points are measured in the hundreds and thousands instead of ones and tens. So, the 10-point ''riichi'' ante mentioned above is actually a 1000-point ante in the actual scoring. Below, the difference in scoring is denoted with a (00) annotation. | ||
** '''[[Scoring table|fu points and higher scoring limits]]''': Japanese Mahjong also follows the Classical Chinese system of calculating base points for triplets, ''kan''s, value pair, and final wait, before doubling the value based on the number of ''han'' earned from ''yaku'' and ''dora''. | ** '''[[Scoring table|fu points and higher scoring limits]]''': Japanese Mahjong also follows the Classical Chinese system of calculating base points for triplets, ''kan''s, value pair, and final wait, before doubling the value based on the number of ''han'' earned from ''yaku'' and ''dora''. This can make scoring hands accurately a bit trickier, so be prepared to need plenty of time and practice to be able to score hands accurately under the full scoring system. | ||
** '''[[Honba]]''': If the dealer manages to repeat their dealership, a ''honba'' marker is tracked. Each ''honba'' adds 1(00) to the payment of each player when a hand is won on ''tsumo'', and 3(00) to the payment of the discarder when a hand is won on ''ron''. ''Honba'' can stack up for multiple wins, and are also accumulated when a hand ends in a draw. If a non-dealer wins a hand, the ''honba'' count resets to zero. | ** '''[[Honba]]''': If the dealer manages to repeat their dealership, a ''honba'' marker is tracked.

** '''Point exchanges at exhaustive draw''': As incentive for players to keep pushing their hands forward, if a hand goes to a draw, players who have not achieved ''tenpai'' will give points to those players who are in ''tenpai''. 30(00) points are collectively given up by the players who are non-''tenpai'', and evenly split to the players who are ''tenpai''. As an additional bonus, if the dealer ends a drawn round in ''tenpai'', they get to keep their dealership (and a ''honba'' is added to the count). | ** '''Point exchanges at exhaustive draw''': As incentive for players to keep pushing their hands forward, if a hand goes to a draw, players who have not achieved ''tenpai'' will give points to those players who are in ''tenpai''. 30(00) points are collectively given up by the players who are non-''tenpai'', and evenly split to the players who are ''tenpai''.

** '''Akadora''': Often, one 5 in each numeric suit is substituted for one that is colored completely red, instead of their usual colors. When one is present in a winning hand, each one is worth 1 additional ''han'' to the final tally. Like other ''dora'' tiles, their presence does not count as ''yaku'' on their own. | ** '''Akadora''' (Red ''dora''): Often, one 5 in each numeric suit is substituted for one that is colored completely red, instead of their usual colors.

Like other ''dora'' tiles, their presence does not count as ''yaku'' on their own. | ||
** '''Multiple ron''': In the simplified scoring section, it was mentioned that if multiple players call ''ron'', only the closest player gets to claim the win. An alternative rule allows for ''all'' players who declare ''ron'' to claim winnings off of the discarder -- and each winner gets their full amount! | ** '''Multiple ron''': In the simplified scoring section, it was mentioned that if multiple players call ''ron'', only the closest player gets to claim the win.
