Mindtrap

Mindtrap is 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 is a puzzle game of immense proportions: 999,999 levels (contrary to popular belief, not 1 million). The player has to rearrange mixed-up dice so they're all in tidy coloured columns, before running out of time or available moves.

Each screen (called a floor), has a set of dice of different colours (Blue, Red, Magenta, Green, Light Blue and White). The player has to shuffle the dice around the play area, using a frame which surrounds 4 of the dice at a time. Dice within this frame can 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 expires.

Later levels introduce a third dimension of the dice scattered between 2 and 5 floors. Players not only have to rearrange the dice on the floor they are on, but must move dice between the floors to finish the level. The number of moves and time allowed are increased with the subsequent number of floors.

To add to the difficulty of the game, some areas of the floor are blocked off to the frame, so different routes are needed to move the dice.

With the game being a mammoth with 999,999 levels, there is a 32 digit alphanumeric password which is given after a successful completion of a level. The password is unique to the player name, which adds that extra depth to the saved game.
