Game for Sinclair Spectrum computers, created for Virgin Mastertronic (Angleterre) in 1989 by Mark Incley and Dave Crummack, inspired by the l'Amiga Infection (see also the page Origins). Simultaneously the similar Amstrad Infection was done by the same authors.
To be played by 2, 3 or 4 players, each one being a human or a computer. This one has 6 levels. It is possible to play with time limits. Blocks may be edited, without being symmetrical.
All the rules, many options
The moving of pieces are classical, as the colours and positions of players when they are two : the human in red in the top-left and bottom-right corners, the computers in blue in the others corners, human plays first.
(here in Windows émulation) (a red piece is going to change the colour of the three neighbouring blue ones)
The pièces have a very good animation, while the sound is gloomy, but in bad quality.
To download this game, go on the Mark Incley site. You may play directly in the site with a java emulator. Be care with the keyboard, it is not easy... You also may use another emulator at cette page. For Windows, I advise the ZX-32 emulator of Vaggelis Kapartzianis.
