The MANSIONPoker.net Poker Dome Challenge was a 43-week series of speed poker tournaments offering a grand prize of US$1,000,000. The tournament aired in the United States on Fox Sports Network from May 2006 to March 2007. The tournament featured a number of technological gimmicks in an effort to increase viewer interest and excitement. Commentating duties were shared by rotating hosts including Barry Tompkins, Jon Kelley, Michael Konik, Michael Gracz, Joel Meyers and Chris Rose with Leeann Tweeden serving as co-host/exit interviewer. Matt Savage was the tournament director.

The series consisted of single table tournaments of six players each. Five of the six competitors qualified through daily freeroll tournaments held at mansionpoker.net. Another competitor came from the National Pub Poker League, an amateur poker league that partnered with MansionPoker.net and qualified its nightly bar tournament winners into a private weekly freeroll. Winners of the online qualifiers were flown all expenses paid to Las Vegas, Nevada and received $500 in casino chips and other amenities.

Professional poker players Tony G, Dennis Waterman and Perry Friedman and reality television personality-turned poker pro Rob Mariano have appeared in the Dome. Nevada casino author Al W Moe appeared in the Dome and his wife, Shannon R Moe, was an alternate selection a month later.
