Zuma Boom 2 by IriySoft

Zuma Boom 2 is a marble-shooting puzzle game where you stop a moving chain before it disappears into the finish hole. Aim colored balls at the line and form groups of at least three matching colors to remove them. Look for shots that set off chain reactions, clearing more of the chain and adding bonus points to your score. This sequel adds 15 levels, armored balls, bridges, and a rainbow-ball bonus. Armored balls need two matches to clear, while bridges allow the chain to cross over itself. These additions make choosing a target as important as matching the next color: each shot needs to help keep the advancing line under control.
