BLACK & WHITE

Copyright (c) 1990s Dan Spil

This game is played on an empty 5x5 board. Each player has 5 stones off board.

 

DROP PHASE - On each turn, each player drops one of his stones on an empty cell. MOVE PHASE - On each turn, each player must do one of the following actions: Use a friendly stone to jump (orthogonally or diagonally) over an enemy stone landing on the immediate empty cell and flipping the color of the jumped stone (black turns white, and vice versa). Jumps are multiple (the player may choose between choices) and mandatory. Move a friendly stone to an (orthogonal or diagonal) adjacent empty cell. GOAL - Wins the player that (i) make an (orthogonal or diagonal) 5 in-a-row, or (ii) stalemate the adversary.

 

An example White's turn. If he moves c4-c3, Black must jump b2:d4 (and the c3 stone turns black). Then White replies d5:d3:b3. If Black moves e1-e2, d1-c2 wins in the next turn with a 5 in-a-row at the 'c' column.

There is a ZRF to play Black & White with Zillions.
