How to Play
To begin, click on a red piece to select it and after that on an empty place to move. You can move up to two places in any direction -
With one place (a drop move), your piece will be copied. With two places (a jump move) your piece itself is moved. If you click 'Moves' your choices are highlighted yellow (drop) and green (jump). Click on 'Moves' again to turn the help off.
After your move all neighbouring pieces of your opponent will turn colour and be yours. Your opponent (the computer) plays blue.
When the last possible move has been made, the player with the most pieces on the board is the winner.
Try not to leave any holes in your positions, since they can be easily occupied, capturing many pieces.
Jump moves are especially vulnerable to leaving dangerous holes.
Early in the game, make drop moves and try to move towards the centre.
This game is a development of Reversi (Othello) and was designed to be effective on a computer.
The gameplay is said to have been invented by Dave Crummack and Craig Galley in the UK in 1988. They both now work in Austin, USA.
It was originally called Infection and programmed for the Amiga, Spectrum and Amstrad.
It was renamed as Ataxx which first appeared in 1990 as a timed arcade video game by The Leland Corporation.
The Infection/Ataxx board is a 7 x 7 square but play is the same.
The more interesting hexagonal board was produced as a flash version for pc, called Hexxagons, and was programmed by Abraham Edlin and
Jason Blochowiak of Argo Software in 1992/3 and recently resurrected by Paul Neave (widely available free).
