I found this one pretty late, but if you see this post in the next few hours, you can pick up Bejeweled 2 ($11.82 PC), from PopCap Games, as a free download, tonight only, until 10:00 PM PST.
Game Description
Get set to play the PopCap game that set the standard in casual gaming! Match sparkling gems three at a time to make them burst in showers of color and points. Match four or more to create flashy power gems that boost your score and your mood with brilliant cascades and combos.
Soar to gem-matching heights in Classic mode, or speed through matches against the clock in Action. For even more dazzling fun, bump up your brainwaves with multi-faceted Puzzles, or enter the Zen state of Endless play. Every match is high-carat fun!
