TOUR DE RUCHE

Copyright (c) 2004 Christian Roullier

This game is played with the following setup (the cells with black squares are not used):

Each player has one tower and four pawns.

  • VISIBILITY - A piece is visible if no other piece is over it. Otherwise, it is invisible.

  • TURN - On each turn, each player must move a friendly visible piece (or pass if it has no valid move):

    • A piece (tower or pawn) adjacent to 1 piece (of either color) moves to an adjacent cell.

    • A piece (tower or pawn) adjacent to 2 pieces (of either color) moves exactly 2 cells in a straight line.

    • A piece (tower or pawn) adjacent to 3 pieces (of either color) moves exactly 3 cells in a straight line.

      • The traveled cells must be empty except the destination cell which may be occupied. In that case, the moving piece moves over the piece(s) already there (which become invisible).

      • A stack is not moved as a unique piece, only the visible stone of that stack can move.

      • Isolated pieces or adjacent to more than 3 pieces cannot move.

  • The red cells cannot be crossed or moved to.

  • GOAL - Wins the player that moves his tower to the enemy tower initial cell.
 
A starting example

Black moves a3 to b4 (it had one adjacent piece) making a stack of size 2.

White moved away its f5 to f6, preparing e4:e6 (if then, d6-e6, White replies f6:e6)
A winning move

Black's move. He moves his tower from b3 to d3 (moving over a white pawn). On the next turn, he may move into the winning cell (since the tower is only adjacent to one piece, he can move to an adjacent cell).
