The process of drawing and discarding, as well as making claims to discard is the process of hand development. As a player, after the initial deal of hands, players have a ''start hand''. So, the aim of a player is to develop this hand into a ''complete hand''. A complete mahjong hand is composed of '''4 melds and a pair'''. The hand may be '''open''' or '''closed''' and have '''at [[Yaku|minimum 1-yaku]]'''. This is a total of 13 tiles plus 1 (the winning tile), like so: | The process of drawing and discarding, as well as making claims to discard is the process of hand development.

There are two notable '''exceptions''' to the 4 melds and a pair pattern. Players can try to form [[Chiitoitsu|seven pairs]] or the rare [[Kokushi musou|thirteen orphans]] hand. Both of these hands are closed by default. | There are two notable '''exceptions''' to the 4 melds and a pair pattern.

Furthermore, when a player calls or declares a ''kan'', an additional ''dora indicator'' tile is flipped. This is called the ''kan dora''. Some rules may allow the ''kan dora'' to be flipped immediately after the ''kan'' call. Other rules have stricter procedures on when the ''kan dora'' tile is flipped. Some make the distinction between the open ''kan'' and the closed ''kan''. Finally, a tile is shifted from the end of the regular wall to the ''dead wall'', in order to maintain 14-tiles in the ''dead wall''. | Furthermore, when a player calls or declares a ''kan'', an additional ''dora indicator'' tile is flipped.

===Claiming discards=== | |||
{{main|Naki}} | |||
As part of the game, players have the ability to claim other player's discards. | |||
Finally, a hand is distinguishable between an '''open hand''' and '''closed hand'''. A closed hand is a player's hand, that had yet to make any claim on a discard. A hand in this state is fully concealed from the other players. In the event a player makes a claim on a discard, then the player's hand changes from a closed hand to an open hand. | |||
Usually, a player's hand value decreases in the event of an open hand, but this may not always be the case, especially for some ''yakuman'' hands. Japanese mahjong strategy centers on knowing when to appropriately make the above calls. Knowledge of the ''yaku'' plays a large part in this decision making process. | |||
