PUSH

Copyright (c) 1995 Steve Bateman

The game is played on a initial empty 8x8 board.

MOVE - Each player inserts a stone onto the board from an edge.  The push may be horizontal, vertical or diagonal, but must be away from the pushing edge (e.g., from the top, the push can only be toward the right, the bottom or the left. Passing is not allowed  If a stone, when pushed meets another stone, this too is pushed on the same direction, and so on... EDGE - A stone pushed off the edge during a push is returned to the player (there are no captures). GOAL - Wins the player which has (at any moment) 5 stones in a row (orthogonal or diagonal).

Bateman says in his rule's description that the game can also be played by 3 and 4 players, and the goals are slightly changed. 

4 example... If White inserts a stone at a3 (pushing right-up), he will occupy cell [1] and Black does not have a suitable answer. If Black plays h4 (pushing left), then White wins at e8. Otherwise, if Black plays anything else, White wins with h4 (pushing left).

This game is very similar to Quixo, where the way both games handle empty cells is different, and Quixo does not permit diagonal shifts. Another game, called Think (described by Gary Duke and Dylan O'Donnell) uses Quixo method (using gray stones instead of row/column shifts) and is played on a 6x6 board, where the only possible pushes are by bottom and right edges. Yet another related game, is Tara.
