Shack PSA: Peggle Nights Free on PC and Mac

BOOM widget 77198 Looking to spread the word about its free PopCap Passport rewards program, the company behind such adorable and addictive hits as Plants vs. Zombies and Bookworm is offering a free PC / Mac copy of its peg-popping, ball-bouncing sequel Peggle Nights.

The only caveat? You have to sign up, meaning "you are required to receive the PopCap Newsletter." Oh, and technically, that free copy of Peggle Nights is meant to be sent to a friend, but we won't tell if you gift it to yourself.

Oh, and don't forget about the three free add-ons that bring more even levels to Peggle Nights, all of which are over on FileShack. Thanks to Rock, Paper, Shotgun.
