Clicking Description:

Clicking is a fun arcade-style puzzle game where you earn points by clicking the clusters of like-colored blocks (in groups of three or more) to collapse the columns. It features: high-quality graphics, good sound effects & music, high scores, 4 levels of difficulty, 10 levels of play, etc.

You don't need to be Einstein to play this game, but it is fun and reasonably addictive as long as you don't already have Repetitive Strain Injury (RSI) in your wrist. Verdict? Clicking is a great little time-waster.
