GALACTRIX.
Rules of the game:
You are competing against an CPU opponent with a thin sci-fi setting. You have laser energy, shield energy, and health: you use laser attacks to reduce your enemies shields and health before they do the same to you. Create rows of 3 or more identical stones to cause various effects. Like all other puzzle games, the row will disappear and be replaced with new random stones -- with luck, the replacements will generate combos for greater effects.
Red Stones = increase laser energy.
Blue Stones = increase shield energy.
Yellow Stones = used for Shield Matrix ability.
Green Stones = used for Shield Matrix and Space Bomb abilities.
Purple Stones = useless in demo.
Silver Stones = useless in demo.
"Bomb" Stones = attack opponent's shields/health without using laser.
At the left side of the board there are three abilities to use: Laser Beam (spend red to attack), Shield Matrix (spend yellow/green to attack), and Space Bomb (spend red/green to set of a random gem on the board). Spend your turn either moving stones or using abilities, but be careful when moving stones because if you don't set three in a row then you've wasted your turn.
