Your
task is placing at least 4 same crystals in row in hexagonal playfield
before time runs out. This can be done by swapping two adjacent
crystals. Row which consists of 4 crystals will disappear. New crystals
fall from the top of playfield and fill holes created before. Row which
consists of 5 or more crystals also creates energized crystal. If a row
consists of energized crystal, this crystal explodes and destroys all 6
crystals adjacent to energized crystal. If there is an energized
crystal destroyed, it also explodes and creates chain reaction of
explosions. As game advances, time runs out faster. Empty crystal
appears after certain period of gameplay to block your moves. Only way
to get rid of it is make it fall from the bottom of playfield.
Game
requires Atari XL/XE with at least 64 kB of memory; it does not need
any extended HW. Music and SFX are played simultaneously during
gameplay. It runs same on PAL and NTSC machines.
Game can be
started in title screen using START button or FIRE button on your
joystick. Game is completely controlled by joystick. Use the joystick
to control the cursor and press FIRE to select crystal. Then move
cursor to adjacent crystal and press FIRE to swap it with the selected
one. If swapped crystals did not make 4 or more crystal row, they swap
back into their original positions. Game can be ended anytime by pressing ESC key.
Scoring
is based on combos, so score is multiplied when disappearance of
crystals leads to next disappearance without intervention of player.
The bigger chain reaction you make, the bigger score you get. You can
receive MegaCombo bonus 10000 points if you destroy 9 or more same
shaped crystals in one move.
