A. small game (3 boards)—grand strategist, 3 boardmen, 0, 1 or 2 agents (for each side)
medium game (5 boards)—grand strategist, 5 boardmen, 1, 2, or
3 agents (for each side)
C. large game (7 boards)—grand strategist, 7 boardmen, 1,2, 3 or more
agents (for each side)
Play begins simultaneously on all boards. Squares on each board are numbered from 1 to 64. White plays first and white pieces are placed on the high numbered sides of the boards.
The team winning the most boards wins the Perplexichess game. If there is a time
limit (as, for example, in some possible classroom uses), boards on which a
conclusion has not been reached shall be awarded to the side with the most
pieces left on that board.
The rules of Flexichess govern moves on each board:
the rules of ordinary chess apply to begin each game
instead of moving, a player may change a rule of chess or introduce a new
rule applying to that board
rule changes must be recorded in writing
no change can affect the movement of more than one kind of piece
rule changes cannot distinguish between black and white pieces
changes cannot be made in the motion of the kings or in the conditions
under which checkmate or stalemate occur.
A grand strategist may remove any piece or his or her own color (except for the
king) from one board and immediately place it on the same relative location on
any other board, provided that the new location was unoccupied. The grand
strategists do NOT take turns with each other---each is free to move as often or as
infrequently as desired.
When one board reaches checkmate, draw, or stalemate, play on that board
ceases and the kings are removed. All other pieces are left in their current
locations on that board. Pieces can still be moved to and from the board as
provided in rule number 5.
The grand strategist may not relocate pieces on a given board, nor may control
the pace of play on any board, but may try to convinced a Boardman to move
in particular ways and can reassign any member of the team to new duties.
However the majority of a team can elect a new grand strategist, with the
incumbent having no vote.
