Claiming rules Allow over-claiming
Over-claiming refers to an act of claiming a discarded tile for a Pung (or
Kong, if jokers are enabled) after one of the other players has claimed
the same tile for a Chow. This can be done unintentionally, but normally
over-claiming is a strategic device: the discard is claimed only to prohibit the
player who claimed the tile for a Chow to improve his hand.
Some rules consider over-claiming unfair and forbid it altogether while other
rules allow it without restrictions or by applying a time limit for to allow a safe
By default Four Winds ignores the concept of over-claiming: in
non-multiplayer games other players' declarations are shown only after the
specified discard delay has passed, so it is not
technically possible to over-claim; in multi-player games other players'
declarations may be shown immediately (provided that the the Hide
competition option is not active), but over-claiming is not
possible, since the declarations are evaluated only after the specified discard
delay has passed. In both game modes, the discarded tile is simply given to
the player whose claim is the highest.
However, if you enable over-claiming, Four Winds handles claims as follows:
a) Non-multiplayer games
- If the human player claims a tile for a Chow after the specified
time for safety threshold (e.g., 3000 msec.) has passed, and no other
declarations have yet been made, computer players are not allowed to
over-claim the human player (unless they use the discarded tile to go out).
If they want to use the discard for a Pung (or Kong), they make the
declaration immediately as a tile is discarded ("early"
declarations are not considered over-claims). If the threshold is the same
as the discard delay, computer players can always over-claim the human
player's (and each other's) declarations.
- As for computer players' Chow declarations, only the limitmaker and
beginner make early Chow declarations (ones that can be
over-claimed). The expert player makes early Chow declarations only
occasionally; the defensive player always makes "safe" (late)
Chow declarations. The human player can over-claim a computer player's Chow
declaration if it is made before the specified time limit (safety
threshold) has passed. If the threshold value is the same as the discard
delay, Chow declarations can always be over-claimed by the human, unless he
has clicked the game board (this is the default configuration for
acceleration, but can be changed) to indicate that he does not want the
discarded tile. So, if you have a possibility to declare a Pung or Kong and
wish to postpone the declaration to see whether a computer player claims the
discard for a Chow, you should not accelerate the game.
- If the human player wants to make a "safe" Pung declaration, he
must claim the tile within the time limit specified by safety threshold.
This is not considered an over-claim and always supercedes computer players'
Chow declarations, no matter when they have been declared (early or late).
b) Multiplayer games
- Computer players behave exactly the same as above.
- Human players' Chow, Pung and Kong declarations are always shown
immediately, disregarding the current setting of the Hide
- If a human player accelerates the game to indicate that he does not want
the discarded tile, he cannot later change his mind and over-claim the tile.
- If the value of safety threshold is the same as the discard delay, human
players can over-claim any Chow declaration, no matter when it is done
(before or after the time specified by safety threshold has passed).
- If the value of safety threshold is shorter than the discard delay, a Chow
declaration can be over-claimed only if it is made before the time
limit has passed. Notice though that if a human player declares Pung (or
Kong) before the specified time limit has passed, the declaration always
supercedes the Chow declaration, even if the Chow is declared after the time
limit (since the Pung declaration is "early", this situation does
not involve an act of over-claiming).
- Note that the time limit specified by the safety threshold is measured
only for local declarations: you cannot see whether other human players'
declarations are early or late since it is likely that the information about
the declaration arrives only after the time limit is passed on your computer. So, if you have
a chance to over-claim, you should always try to claim the tile, even if
other human players' Chow declarations seem to be "late". The same
applies to other human players' Pung and Kong declarations: they may be
"early", even if they are shown after the time limit has passed on
your computer. So don't be surprised if an apparently late
"Pung" declaration supercedes your "safe" Chow
To specify the over-claiming rules:
- Choose Preferences on the File menu.
- From the Rule Presets list, choose a customized rule preset.
- Choose Claiming under the Rules section of the
- To enable over-claiming, check the Allow over-claiming box.
- As the setting is enabled, Four Winds automatically uses the discard delay
as the value for Safety threshold.
- The default value means that over-claiming is always allowed, no
matter whether a Chow is declared early (before the specified time has
passed), or late (after the specified time has passed). Similarly, Pung
(and Kong) declarations are always considered as non-over-claiming
declarations and will supercede any Chow declarations.
- If you specify a shorter value, declaring a late Chow is
considered a safe Chow and cannot be over-claimed. In this case Pung
declarations must be made within the specified time limit to be
considered as non-over-claiming (otherwise they will supercede only
early Chow declarations).
