AMAZONS

Copyright (c)1988 Walter Zamkauskas

Amazons is played on a 10x10 board, with the following setup:

  • MOVES - White moves first, and turns alternate. Each turn consists of two parts, and both parts are mandatory.
    • The player first moves one of his amazons. Amazons move as a chess queen. Amazons may not jump over or land on other pieces or arrows.
    • Next, the Amazon which just moved "fires an arrow" from its new location. Arrows can be show in any direction, the same as a chess queen, and may not jump over or land on other pieces or arrows. Once an arrow lands, it acts as an immovable barrier to all arrows and amazons.
  • GOAL - The first player that cannot finish his turn, loses.
 
An example

White moves 1. g1-b6,c7. The arrow landed on c7, so neither player can cross that intersection.

There is a ZRF to play Amazons with Zillions.

There is also a variant Killer Amazons where it's possible to capture any Amazon of either color. 

A 1990 uncredited video game is Joust, is played in a 8x8 board with two Chess knights. One player places his knight in his first row, and the second player places hers on her first row. However, the second knight cannot be directly opposite neither of the mirror column (e.g., if the first knight is of c1, the second canot be on c8 or f8). Then, on each move, a knight jumps to empty squares and leaves a wall behind. So, knights can jump over walls. A stalemated player loses the game.

Another variant from Chris Huntoon, in 2003, Cowboys also uses Knights on a 8x8 chess board (with no capture):

A similar game is Emil Danielsen's Zappazon (2026) played on a 9x9 board, where players initially place two pieces each. The pieces move by making two Knight steps in sequence, then shoots the arrow (using the traditional Queen range) to place a new wall.

In r.g.a there was a proposal for a Pencil & Paper variant:

It's the same as regular Amazons, except that the square from which your Amazon moved automatically becomes an arrow square after the Amazon moves away from it, but before it shoots its new arrow. This means that you can play it with X's and O's for the Amazons, and color in the arrow squares, or use a superimposed X and O together for all arrow squares. The game is faster, since each move uses up two empty squares instead of one, and tactics are different, since it becomes much harder to get back into a region once you move out of it. There's even a little more subtlety to figuring out how many endgame moves a given territory will produce.

Bill Taylor and João Pedro Neto proposed, in 2004, a much more dynamic variant: 134* Amazons, where within a turn, all moves must be from different pieces, and the player loses the match if he cannot make all his moves.

Here's a game by the authors:

Another variant from Taylor and Neto, and a mix with Cul-de-Sac, is 2007's Tromazons:
