The hip-hop hitmakers went head to head over American football game Madden '09 in September, after Bow Wow took exception to The Game's boasts that he was the best celebrity Madden player.
He challenged the Dreams hitmaker to a winner-takes-$100,000 marathon - but the 22-year-old lost the match 23-55.
However, The Game claims Bow Wow has yet to hand over the full amount - and he's issued a new double-or-nothing challenge on another sports game - the Black College Football Experience (BCFE) on the Xbox 360.
He says, "I played football before; Bow Wow was my first victim, he lost $100,000 in front of a million people. He still ain't (sic) paid me all my money yet, but that's my man, I'ma (sic) get it from him. Or maybe we can bet double or nothing on this BCFE... but he ain't (sic) ready, he's too young."
