CBS is expanding its unscripted programming slate with three distinct bets on familiar television pleasures: workplace revelation, family-friendly game mechanics and high-pressure competitive strategy. The network has ordered a refreshed 12th season of Undercover Boss, now set to be hosted by Drew Carey, as well as two new competition series, Stacks of Cash and 24 Hour Millionaire.
The three projects share a broad category but not a single audience promise. Undercover Boss is built around corporate leaders working anonymously inside their own businesses to see their operations and employees firsthand. Stacks of Cash combines question-answering with a physical stacking challenge. 24 Hour Millionaire, meanwhile, is designed as an endurance-heavy contest of social maneuvering and physical performance, with a guaranteed $1 million winner after one uninterrupted day of play.
That range matters. Rather than treating “unscripted” as one genre, the orders cover three different viewing modes: emotional workplace storytelling, accessible game-show tension and the more tactical, alliance-conscious competition that viewers associate with social strategy formats.
Undercover Boss returns with Drew Carey in the host role
Undercover Boss will return for its 12th season after being off the air since 2022. Its basic premise remains straightforward: senior business leaders conceal their identities, enter roles within their own organizations and gain direct exposure to how the company works at ground level.
The new version is being described as a refreshed take, and the clearest announced change is Carey’s arrival as host. CBS executive vice president of alternative series Mitch Graham said the format will continue to focus on undercover journeys and the hard-working employees at their center. The wording suggests the revival is not abandoning the core emotional engine of the series: the contrast between executive-level assumptions and the daily realities faced by workers.
Carey brings long-running CBS game-show experience to the assignment. He recently reached his 20th season hosting The Price Is Right, a role that requires clear communication, fast reactions and a welcoming on-camera style. Those skills do not automatically make Undercover Boss a game show, of course, but they could suit a format that has to move viewers through setup, concealment, discovery and resolution without losing sight of the people affected by each corporate decision.
The original series began on CBS in 2010 and won the Emmy for outstanding reality program in both 2012 and 2013. Studio Lambert is producing the returning season. Stephen Lambert, Jack Burgess, Abigail McCarthy, Niall O’Driscoll and Tim Harcourt are executive producers.
What “refreshed” can mean—and what has not been confirmed
There are no further confirmed details yet on the exact structural changes, participating organizations, episode count or premiere timing. So “refreshed” should not be read as a promised wholesale reinvention of the show. At this stage, the concrete announcement is a new host and a new season in pre-production.

Still, the host change gives the return a practical identity of its own. Revivals often have to balance recognition with a reason to revisit the format. In this case, the familiar undercover premise supplies the recognition; Carey is the most visible sign of a new presentation. Whether that also means changes to pacing, interviews or how the show frames the leaders and employees is not yet known.
Stacks of Cash turns trivia into a building problem
Stacks of Cash has already filmed its episodes and will be hosted by Mike O’Malley. Six contestants answer questions to earn unusually shaped blocks, then use those pieces to build their way toward a gold line.
The mechanism is simple enough to explain quickly, which is useful for a family game show, but it contains two pressures rather than one. Knowledge earns the materials. Placement determines whether those materials become progress. A contestant can therefore be strong at answering questions and still face a difficult spatial puzzle once the shapes begin to accumulate.
Why the block shapes matter: if every piece were identical, stacking would chiefly be a test of steadiness. The use of unique shapes introduces planning and risk assessment. Players must decide how to create a stable base, how high to build, and when an apparently useful piece may make a later placement harder. The gold line creates a visibly legible finish condition: audiences should be able to see how close a structure is to success even before the result is decided.
This kind of physical game-show design can make each round understandable at a glance. Trivia delivers the right to act, while the stack makes the outcome tangible. It is a different proposition from a strategy show where players need to track alliances and hidden information across many hours. Here, the central drama appears to be whether earned advantages can literally remain standing.
O’Malley is known to television audiences as an actor from Yes, Dear, and he has more recently served as a showrunner on series including Heels and Survivor’s Remorse. His involvement gives the new format a host with experience on both sides of television production, though the announced premise remains centered on the contestants’ question-and-construction challenge rather than any additional format twist.
The series is based on a format developed by Eureka Studios Group Pty Ltd and Seven Network Limited. Chris Culvenor, Paul Franklin, Rikkie Proost, Sonya Wilkes, David Tibballs, Ves D’Elia and Ed Egan are executive producers.
24 Hour Millionaire aims for nonstop social strategy
The most overtly competition-focused of the three orders is 24 Hour Millionaire. It assembles experienced game players for 24 consecutive hours of social strategy and physical contests, with one contestant guaranteed to win $1 million when the clock runs out.
The pitch places as much importance on fatigue and time pressure as it does on individual challenges. Players will have no breaks or rest, and must keep making social, strategic and physical decisions throughout the day. The format is in pre-production after spending the past year in development at CBS.
Social strategy is the essential term here. It means winning cannot rest solely on strength, speed or general knowledge. Competitors also need to evaluate whom to trust, recognize emerging threats, communicate persuasively and adjust when the group dynamic changes. In a contest advertised as continuous, those tasks can become more difficult as tiredness reduces patience and clear thinking.
That design makes the 24-hour limit more than a branding hook. A normal competition can distribute pressure across days or episodes. This premise concentrates it. Every alliance, physical task and decision takes place under the knowledge that recovery time is unavailable and that the grand prize will be settled by the end of the same day.
It also differentiates the show from a traditional quiz competition. Facts may be useful in particular challenges, but the announced rules emphasize adapting under pressure. Fast judgment, threat assessment and performance become connected skills rather than separate rounds. Players who excel in a single lane may still need partners; players who build trust may need to prove they can endure the physical side.
Fly on the Wall Entertainment, whose producers are behind Big Brother, is producing 24 Hour Millionaire. Allison Grodner and Rich Meehan are executive producers. Their involvement is a meaningful fit for a show foregrounding social relationships, shifting power and game awareness, though CBS has not detailed its specific elimination system, challenge roster or casting lineup.
A deliberately broad unscripted slate
Graham described the trio as part of an effort to build a deeper year-round unscripted lineup. The orders make that strategy easy to see in practical terms. Undercover Boss arrives with an established premise and a new host. Stacks of Cash offers a compact setup suited to viewers who want questions, spectacle and an immediately visible objective. 24 Hour Millionaire reaches toward the increasingly demanding end of reality competition, where social decisions and physical performance are inseparable.
The contrast is particularly sharp between the latter two. In Stacks of Cash, the game’s central obstacle is external and physical: a stack must reach a line. In 24 Hour Millionaire, the obstacles include the other players’ motives, the physical competitions and the cumulative effect of a clock that does not pause. One format turns earned answers into building materials; the other turns every relationship into a potential tactical choice.
For audiences who enjoy game mechanics, that distinction is useful. A game mechanic is the repeatable action or rule that generates decisions and tension. The stacking mechanic encourages balance, placement and visible risk. The 24-hour mechanic encourages prioritization, resilience and strategic reads on people. Both provide a clear play pattern, but they ask viewers to invest in very different kinds of suspense.
The social component of 24 Hour Millionaire may also appeal to viewers who enjoy watching group dynamics develop around structured activities—a different kind of activity-based interaction from the group setup discussed in our look at Tinder’s group hangouts. Here, however, the stakes are expressly competitive and the final prize is $1 million, so cooperation and rivalry are likely to exist side by side.
No premiere dates have been announced for any of the three series. For now, the production statuses draw a clear line: Stacks of Cash has finished filming, while both Undercover Boss and 24 Hour Millionaire remain in pre-production. What is confirmed is a varied three-pronged expansion: an Emmy-winning reality format returning with Carey, a quiz-and-construction game show led by O’Malley, and a one-day competitive pressure cooker built around strategy, stamina and a million-dollar finish.
