Gem’X
Like so many other puzzle games of the time, this game involves tiles of
different colours, which must be manipulated to clear a succession of
increasingly-difficult levels.
The basic idea is that you are presented with 2 sets of tiles, and must make
the left one identical to the ‘control’ set on the right. The colours are
defined in a sequence – red, green, blue, purple, yellow – and when you click
on a tile, that tile’s colour moves forward by two in that sequence (for
example a blue one becomes yellow), whereas the tiles next to it move by one
colour (for example, blue becomes purple).
Any that move past the end fo the sequence disappear, causing surrounding
blocks to drop. You get a limited number of moves, and limited time as well.
Fortuantely there are passwords, delivered by cutely-drawn naked Japanese
girls (although the private parts are covered up).
