Ben 10: Alien Force

Our planet is once again under attack by an alien force, and Ben and his team are stepping in to defend Earth. Help Ben save the planet from a new wave of alien invasion by clearing as many tiles as possible in this free Flash puzzle game. Slide and arrange tiles vertically or horizontally to match three or more identical monsters, and when a match is made, the monsters will disappear and be added to the Super Stack (in the bottom right corner). Additional bonus points are awarded for Super Combo stacks.
