Franklin Veaux, creator of the sex game Onyx, offered Playboy Radio listeners a discount code so you can register your copy for $29.

Onyx guides two to six players through hours of sexual exploration in a Monopoly-meets-Truth-or-Dare-meets-Cranium kind of way. Look for my full report in a month or two, when the magazine publishes my article; but the gist is that the game is surprisingly fun and will provide hours of entertainment through the cold dark winter to come.

You can download Onyx and play at the make-out level for free, but to get to the spicy stuff, you’ll want to register. The code is playboy08. (All lower case, btw, as caps probably won’t work.)
