In Puzzloop Free, colored balls advance on a spiral rail; the game ends once the balls reach you. Firing back your own balls lets you match colors -- matching three or more colored balls eliminates them until you clear the screen. Familiar gameplay is spiced up with power-ups that stop time or destroy all the balls of a particular color. You’ll need all the help you can get because enemies that wouldn’t be out of place in a platformer, are constantly trying to thwart your progress by blocking your shots. Although each level is just the same rail, Puzzloop Free offers fast and furious challenge while it lasts, and you can make balls move faster for a harder game.
