Rubehouse takes the classic chain reaction puzzle game to a new level on the iPad with great eye candy and soothing music.

As with most chain reaction games, your job is to destroy as many particles as you can by initiating a single detonation. Any particle that it hits will explode, causing a chain reaction of explosions that take out any nearby particles. You need to destroy a certain number of particles for each level.

As levels progress, there are more and more particles, and you must destroy an ever-increasing percentage of them just to achieve a bronze star and unlock the next level.

Higher percentages will unlock silver and gold achievements.

Only 1% of users have unlocked the gold achievement on the last level - will you be one of them?
