Placement of Dominos in 42 TournamentsHere are extracts from different tournament rules that address placement of dominos after the shake (as of 22 Mar 2018):
A. The former N42PA rule II-4 (2015) specified only one placement of drawn dominos: "Dominoes shall be lined up in two rows with three in the front (near the player), and four in the back (near the table's center)."
Note: The American Institute of Chemical Enginers (AIChE), Gulf Coast Section, specified in their 2004 tournament rule #6 that "Dominoes must be set on table with backrow of 4 dominoes & front row of 3 dominoes and may not be rearranged during play. If everyone agrees, dominoes may be held in hand instead."
B. The current N42PA rule 8 specifies options for placement of dominos: "Dominos must be placed in a 4-3 or 3-4 format once you draw from the shake. Once the bidding starts, you cannot rearrange your dominos for the rest of the hand. This includes pushing your dominos together as the hand plays out."
C. The current Austin 42 Club rules state placement options, also: "Dominos must be placed in a 4-3 or 3-4 format once you draw from the shake. Once the bidding starts, you cannot rearrange your dominos for the rest of the hand. This includes pushing your dominos together as the hand plays out."
D. The current Hallettsville State Championship tourney rule 6 specifies options, also: "Dominos must be placed up facing each player in a 4-3 or 3-4 arrangement."
E. The current Austin 42 organization rules state placement options with game-enduring restrictions: "Positioning of Bones: Bones may not be held (except for initial viewing) and shall be lined up in front of the player in two horizontal rows stacked 4-3 or 3-4, maintained consistently from hand to hand and game to game. Bones may not be moved nor pushed together once play begins."
Extract(s) A had no optional domino placements. Extract E option is limited to only the first hand of play. The other three extracts allow different options to be used in each hand of play in every game.
