Turn pigs against each other in this chain reaction game! Click anywhere on the screen as you attempt to cause chain reactions that will result in the most pig deaths. The meter on the bottom of the screen gives you an idea of how many deaths are needed to complete the level and earn stars. In addition to killing pigs, you can earn stars by causing pigs to touch the ones in the stage. Stars will make upgrades available for purchase, while money is needed to purchase the upgrades.
