To use these tiles, regular five tiles are switched with the red dora. The remaining four tiles are four flower tiles, which are not used at all. Typically, Japanese tiles are individually about the size 16 mm x 19 mm x 26 mm WLH. Like most mahjong tile sets, these tiles are capable of standing on their own. The tiles may be subgrouped in a couple different ways.
The first distinction is the separation by suits and tile types. Three groups of tiles form the numbered suits, while another group form the honor tiles , which can be further subdivided as dragons and winds. Within the numbered suits, the tiles numbered 2 through 8 are composed of the simples , while the 1's and 9's are separated as the terminals. The Chinese characters or Japanese kanji are used to indicate the numbers While some sets have the alphanumeric representations of the numbers superscript on the upper right corners, it is actually best to remember the kanji for Standard Japanese sets lack these alphanumeric superscripts.
The character for man means "ten thousand". The symbols represent the use of coins. Ordered , it is special to note the 1-sou tile which is marked with a large bird instead of 1-stick to discourage cheating by tile alteration.
They are indicated as East, South, West, and North. The wind tiles correlate to the player seating , and so therefore, it is best to remember the wind tiles in the East, South, West, and North order, as they correspond to the seating order. Likewise, this is significant to note for yakuhai. The noten riichi would naturally show noten; and it is subject to chombo.
Likewise, chombo is applied if a win is called, as the hand's winning status would be verified only to reveal an invalid hand. Players may escape this dubious position, when another player wins the hand or has committed a chombo penalty. An abortive draw may also prevent the chombo penalty, except suucha riichi. Kan during riichi is a discretionary play. Players must take not of the hand composition to determine, whether the kan is allowable or not. Disallowable calls either alters the hand's waiting pattern or alters the hand's composition, where tile groupings are changed.
Improper calls are subject to chombo. During riichi, a player may be furiten. In this case, the riichi is considered to be a furiten riichi. Likewise, after calling riichi, a player may decline the option to call on a winning tile, whether it be by self-draw or by discard. However, if a win is declined, then the riichi declared hand is subject to furiten for the remainder of the hand. Thus, all tiles discarded after the riichi declaration, as indicated by the discarded sideways tile, are considered to be guaranteed safe tiles.
While it is advised to declare a win on the first opportunity, some plays may require a player not to do so under very specific circumstances. Of course, such play requires caution. When a riichi declarer wins, he may flip the tiles underneath the dora and kan dora indicators.
These flipped ura dora indicators may increase the value of his hand. Tochuu ryuukyoku, or abortive draw, is in effect when suucha riichi occurs. In this case, three riichis have been called; and a fourth one is called in place. If the discarded tile is not claimed for a win, then the hand ends. The principle works exactly in the same way as the original riichi. However, there is an added bonus of 1-han attached, which is earned by revealing either the hand or the tile waits.
This naturally eases everyone else's ability to defend against the riichi. In general, the intent involves winning by self-draw. As a further optional rule, yakuman may be awarded if any player actually plays into the open riichi. This is more or less a harsh penalty for playing into a revealed hand. Many official organizations and tournaments do not implement open riichi. It is more or less reserved for casual or gambling game settings.
For any given hand, more than one player may call riichi. In English, this is often referred to as the "chase riichi". Oikake has one distinct advantage of an ippatsu ron chance against any previous riichi hands before taking a draw. After all, defense is no longer a factor to those hands, as they are committed to discarding non-winning tiles.
The hands are essentially engaged in a "riichi duel" provided that they have different waiting tiles.
