The latest free "On the House" game from EA and Origin is none other than Bejeweled 3 from PopCap.
Bejeweled 3 is a truly classic “match three” puzzle design where you’ll link gems of various colors. Find the best combos to cause huge, cascading links that’ll double, triple…even quadruple your score. Try all eight game modes as you make those gems vanish.

As with all of these On the House titles, the game won't be offered for free forever. So, if you want a free copy of Bejeweled 3 on Origin, you should act fast.
