In this game show hosted by Neil Patrick Harris, players answer trivia to win spectacular hidden prizes — but can they keep them from the competition?

Eight dynamic duos shoot their shot at tricky trivia questions in the hopes of getting to the grid and closer to an electrifying prize.

Play the game or keep it cute? The contestants show their strategic stripes and gamble big on a box in pursuit of the jackpot.

Stolen looks and power plays cause some contestants to change their tune when a shocking wildcard brings the competition to a boil.

It's beginning to look a lot like elimination as a prize fight ignites the race to the Super Box. Who will sail smoothly — and who will go ho-ho-home?

The remaining teams watch out for wildcards and try to steer clear of drama as the game kicks into high gear and strategy becomes a slippery slope.

It's anyone's game — but only one duo can leave with the Super Box. After jaw-dropping twists and turns, it's finally time to find out: What's in the box?
