Mindtrap was a computer game for the ZX Spectrum computer. Made by Predrag Beciric and released in 1989 by Mastertronic Ltd, it was released on other platforms such as the Commodore 64 and the Amstrad CPC. Released for the 48k ZX Spectrum and better, at a cost of £1.99, Mindtrap was an extremely large puzzle game, with some 999,999 levels. The object of the game was to rearrange grids of coloured dice so that they all aligned, before running out of time or available moves.
Each screen (called a floor), had a set of dice of different colours (blue, red, magenta, green, cyan and white). The player had to shuffle the dice around the play area, using a frame surrounding 4 of the dice at a time. Dice within this frame could be rotated 90° around a central axis, with the ultimate aim of lining up the dice in the correct colour before the time and move limit expired.
Later levels introduced a third dimension of the dice scattered between 2 and 5 floors. Players then had to rearrange the dice both on the floor they were on and between the floors to finish the level. The number of moves and time allowed increased with the subsequent number of floors.
To add to the difficulty of the game, some areas of the floor were blocked off to the frame, so different routes were needed to move the dice.
The game created a 32 digit alphanumeric password after a successful completion of a level, which was unique also to the player name, to allow later resumption.
