While we wait to see whether Donald Trump builds his wall, his former employer has set a construction date for its version. Make that a premiere date — January 3 at 8 PM, to be exact, for NBC’s The Wall, a new game show hosted by @midnight‘s Chris Hardwick, who also executive produces along with LeBron James.

The 10-episode series will feature two-person teams related by family, friendship or life experience. They’ll compete for cash that can be won or lost in an instant, depending upon whether a ball bounces their way, or a trivia question is answered correctly. The rules are simple: Get a question correct and a green ball will fall down the four-story wall and add the value of the slot to the players’ winning total. Miss a question and an ominous red ball will fall and deduct the value from the team. Teammates have to work together to build a huge cash prize. As the game progresses, the stakes get even higher when one player is sent into an isolation room behind the wall. It is here where the pair’s faith in each other will be tested as the teammates play the remainder of the game without any communication. More than $12 million is on the line every night, the network says.

The series will get a pair of preview airings: 10 PM December 19 after the America’s Got Talent holiday special and again at 10 PM January 2, following — nudge, nudge — the premiere of The New Celebrity Apprentice.

The Wall is a collaboration between SpringHill Entertainment and Glassman Media with James, Hardwick, Maverick Carter and Andrew Glassman serving as EPs. The series was developed by Glassman Media in conjunction with CORE Media.
