Apparently, this game has been on the net awhile.
50 blue orbs get launched into the air, and you trigger a single explosion by clicking anywhere on the screen.
Each orb caught in the blast explodes itself, creating a chain reaction.
The goal is to catch as many of the blue orbs in the resulting explosions before gravity pulls them back to the ground.
Each game lasts 3 rounds, with a maximum score of 150 total points.
Click the dark blue Kanji script to begin the first round.
