Tenable is a British game show presented by Warwick Davis and briefly Sally Lindsay, airing on ITV1 from 14 November 2016[1] to 30 August 2024. On each episode, five contestants attempt to win up to £125,000 by filling in lists of 10 items each.[2]

Gameplay

[edit]

The five contestants who have a prior relationship play the game as a team; one is designated as the captain. The goal in each round is to give as many answers as possible out of 10 in a factual list that fits a particular category, such as "The 10 'TAN' countries" (countries whose names in English include the letter sequence TAN) or "The first 10 UK cities after Belfast alphabetically." Money accumulates in each of the first five rounds according to the table below.

For most questions, the host provides a brief explanation of what answers can and cannot be accepted as correct. All correct answers are displayed on a triangular board as they are given. As of the 2020 Christmas Special, some rounds begin with a list of 10 clues displayed on the board; one for each of the required answers. If a contestant's answer is correct, it is shown in place of its corresponding clue. At the end of every round, the host reveals any correct answers not given by the contestant(s) playing it.

Contestants who are deaf or hearing-impaired are allowed to have an interpreter on the stage, who may interpret between spoken words and sign language. However, the interpreter may not suggest answers or take any other active role in the game.

Rounds 1 to 4

[edit]

After hearing the category for each round, the captain designates one teammate to play it. Each teammate may only play one round and may not confer with anyone else. The one teammate who is not chosen for Rounds 1 through 3 must play Round 4 by default.

The contestant must give at least five correct ("tenable") answers in order to qualify for the Final, and may stop after any answer at or beyond this point and bank any money earned. If the contestant completes the list, they automatically advance and bank the money.

Two forms of assistance are available until the fifth correct answer has been given:

  • Nominate: The contestant may choose one teammate to provide an answer, then either accept or reject it at their discretion. May be used a maximum of three times during the entire game.
  • Overrule: The captain may reject an answer they believe to be incorrect and give a different one in its place. The contestant's answer is tested first; if it is correct, they are not credited with that answer or awarded any money. May be used once per round.

The contestant is also given one life, which allows them to continue without penalty at any time after giving an incorrect answer or being overruled in favour of one given by the captain. A second such mistake ends the round immediately, eliminates the contestant from the game and forfeits any money earned during the round.

Round 5

[edit]

The captain plays this round under the same rules as the first four, with the following changes.

  • The overrule option is removed from play, but the captain is still given one life and may use any nominates remaining from Rounds 1 through 4.
  • After any correct answer that awards money, the captain may choose to reinstate one eliminated teammate in exchange for dropping back one step on the prize ladder shown above.
  • Reinstated teammates may not be nominated to provide answers and will only advance to the Final if the captain either completes the list or chooses to stop.
  • Any teammates who have not been reinstated at the end of this round are permanently eliminated from the game without any opportunity to share the prize money if won. The same is true for any teammates reinstated by a captain who goes on to fail the round.
  • Regardless of the outcome, the captain advances to the Final.

Final

[edit]

The remaining contestants/full team select one of two categories and are given a list pertaining to their choice. They must give one answer at a time, starting with the captain and then proceeding through the other teammates in the order that they played Rounds 1 to 4. Nominates, overrules and lives are no longer in play and no conferring is allowed. Any contestant who gives an incorrect answer is immediately eliminated from the game. Completing the list awards the entire jackpot, split equally among the contestants participating in the Final, while failing to do so awards nothing.

The maximum potential jackpot is £125,000, achievable by banking the full £25,000 in each of Rounds 1 to 5. If the team fails to bank any money during the game, the default jackpot is £500. As of Series 6, if the team fails to complete the list, each member receives a Tenable-themed tea towel as a consolation prize.

Tenable: All-Stars and Specials

[edit]

A celebrity version under the title Tenable: All-Stars aired sporadically in 2019.

This version is almost the same as the civilian version with one difference where the celebrities receive £1,000 for their charities if they fail to complete the final list. In the 2019 Christmas special, they receive £2,500 for their charities.

There was a Soccer Aid special in 2022 with members of the Glasgow Rangers women's football team taking part.

Tenable is a British that aired on ITV from 14 November 2016 to 30 August 2024. Hosted primarily by , with serving as a guest host for a brief period in 2021, the programme features teams of contestants answering questions based on lists of the top ten in various categories, aiming to reach a "Tenable" score in the final round. Produced by Thief Productions for , it ran for multiple series and specials, including celebrity editions.

Overview

Concept and Format

Tenable was a British daytime quiz show on featuring teams of five contestants, typically close-knit groups such as members or friends, who collaborated to answer questions drawn from pre-researched top-10 lists across varied categories including history, pop culture, and sports. One contestant was designated as the team captain, responsible for selecting categories and assigning players to individual challenges, while also possessing the ability to overrule answers in certain situations to guide the team's progress. The show was axed after seven series, with the cancellation announced in September 2024 and no revival planned as of November 2025. The central premise revolved around constructing the "Tenable Tower," a 10-letter word built progressively by successfully completing these top-10 lists, with each list corresponding to a specific letter and requiring players to name relevant items—such as the first ten films for a pop culture category—to advance the tower. The objective was to accumulate cash through accurate responses while ensuring team survival, as individual players risked elimination if they failed to contribute at least five correct answers in their solo attempts, thereby preventing them from participating in the final jackpot round. Prize mechanics centered on banking money per completed list, where five correct answers yielded £1,000, scaling up incrementally to £25,000 for all ten items, allowing the team pot to grow with each successful contribution to the tower. The maximum potential jackpot of £125,000 was achievable if the full amounts were banked across the game's stages, with winnings ultimately split among the remaining team members who reached and performed in the endgame. Episodes ran for approximately 45 minutes and were scheduled in ITV1's weekday daytime slot.

Hosts

Warwick Davis served as the primary host of Tenable from its premiere on 14 November 2016 until the final episode on 30 August 2024, presenting over 300 regular episodes and all specials aside from periods of substitution. An English actor renowned for his roles as Professor Flitwick and Griphook in the Harry Potter film series and as Wicket the Ewok in Star Wars: Return of the Jedi, Davis brought his established screen presence to the quiz show, hosting solo without co-hosts or assistants. His hosting style featured a humorous and engaging delivery, often incorporating jokes and light-hearted interactions to encourage team collaboration among contestants. In April and May 2021, actress substituted for Davis across 25 episodes of series five, stepping in due to his scheduling conflicts with other filming commitments. Known for portraying in the ITV from 2001 to 2006, Lindsay adopted a warm and relatable approach, describing her style as relaxed while focusing on building rapport with contestants and cheering them on. There was no permanent host transition following Lindsay's stint, as Davis returned to full duties for subsequent episodes and series. Davis's celebrity status from major film franchises enhanced the show's visibility and appeal during its eight-year run.

Production

Development and Production Company

Tenable debuted on 14 November 2016 on ITV1 as a daytime quiz show. The program was developed by Initial, a production company that forms part of Banijay UK, focusing on a team-based format where contestants answer questions drawn from top 10 lists to build a virtual tower and accumulate cash prizes. ITV commissioned the show for multiple series, leading to the production of seven regular series totaling 306 episodes, in addition to variants like All-Stars editions. The core production team at Initial was led by executive producer Richard Greenwood, with no individual creators credited beyond the company's involvement. Designed as an efficient daytime production, Tenable featured escalating prize pots that could reach £125,000 for a perfect final round, appealing to a broad audience through its play-along style. The series concluded after its seventh run in 2024, when ITV opted not to renew it.

Filming and Set Design

The first series of Tenable was filmed at the in , , in 2016. Subsequent series from 2017 to 2024 were recorded at in Iver Heath, , selected for its expansive facilities suitable for television production. The set features a central "Tenable Tower," a prominent structure with 10 illuminated slots designed to represent the top 10 positions in each category list, lighting up progressively as contestants correctly name entries. Teams stand at dedicated podiums equipped for multiple players, while surrounding digital screens display category prompts, answer lists, and visual aids to enhance the on-air presentation. Episodes are typically shot in blocks of around 3 per day in front of a live to capture energetic responses, with handling the addition of , sound effects, and thematic music to finalize each 60-minute program. Technical aspects include custom software developed for real-time verification of contestant answers against pre-researched top 10 lists, ensuring accuracy during . Dynamic focuses on the tower to highlight progress and tension as slots fill. Over the run, the core set design remained consistent, with minor updates to lighting and digital elements for refreshed visuals in later series, maintaining the show's signature look without major overhauls.

Gameplay

Rounds 1 to 4

The first four rounds of Tenable consist of individual challenges where non- team members attempt to name items from top-10 lists in assigned categories, building the team's cash pot while qualifying players for later stages. A team of five—comprising one and four teammates—competes, with the captain selecting which teammate plays each round based on the announced category, ensuring each teammate participates exactly once across these rounds. Categories typically involve survey-based top-10 lists tied to a theme, such as the top 10 countries beginning with a specific letter or the top 10 films in a series. In each round, the selected player provides answers sequentially, aiming for at least five correct responses to qualify personally and contribute to the team's progress. Correct answers are validated against the pre-determined list, and the player may choose to stop after five or more to secure the winnings or continue for higher amounts, though two incorrect answers (including failed overrules) end the round without banking if fewer than five were achieved. The team has access to limited aids: up to three "nominate" lifelines per game, allowing the player to solicit a suggestion from a teammate (which they can accept or reject), and one "overrule" per round, where the captain proposes a replacement for a given answer that is then verified separately. Eliminated players (those with fewer than five correct) sit out subsequent participation but the banked money from successful rounds carries over to the team's total with no risk of loss. The Tenable Tower is a display board that reveals correct answers from the top-10 list as they are provided. Winnings scale with the number of correct answers achieved in a round, as shown below:
Number of Correct AnswersAmount Added to Pot
5£1,000
6£2,500
7£5,000
8£10,000
9£15,000
10£25,000
These values remain consistent across rounds 1 to 4, emphasizing cumulative pot-building over round-specific escalation. Qualifying players (five or more correct) advance to the final, tracking team strength toward . Strategically, the captain focuses on matching teammates' expertise to categories—such as assigning a history enthusiast to historical events—to maximize qualifiers and pot size, ideally securing three or four successful rounds for a robust foundation before the captain's solo effort. This assignment process rotates responsibility among teammates without a fixed order, prioritizing team strengths to avoid early eliminations and ensure broad participation. Each round typically spans 8 to 10 minutes, allowing for tense decision-making on when to stop or push for more.

Round 5

In Round 5, the team captain plays solo, attempting to name items from a top 10 list in the announced category to bank additional prize money and potentially reinstate teammates. Unlike Rounds 1 to 4, the overrule option is unavailable, forcing the captain to rely solely on their own knowledge without substituting teammate answers, though remaining nominate lifelines may be used with non-eliminated teammates. The captain provides answers one at a time and can stop after any correct response or continue until giving an incorrect one, with each correct answer revealed on the Tenable Tower display. If the captain names fewer than five correct answers before stopping or erring, no money is banked from this round, though the captain always advances to the final. Achieving five or more correct answers locks in according to the : £1,000 for five, £2,500 for six, £5,000 for seven, £10,000 for eight, £15,000 for nine, and £25,000 for ten, added to the total accumulated from prior rounds. The round concludes upon an incorrect answer, voluntary stop, or completion of the list. A distinctive mechanic in Round 5 allows the to reinstate eliminated teammates from previous rounds, potentially enlarging the for the final. After any correct answer that reaches or advances a money level (starting from the fifth correct), the captain can opt to bring back one eliminated player by forfeiting the incremental value for that step, effectively regressing the money ladder by one position—for instance, sacrificing the upgrade from £1,000 to £2,500 to reinstate after six correct answers. This process can be repeated after each subsequent money-awarding answer, enabling up to four reinstatements (one per eliminated teammate), but each comes at the cost of reduced winnings from the round. Reinstated players advance to the final alongside the captain only if the captain completes the list or stops successfully, but contribute no additional cash from Round 5. Non-reinstated players are permanently eliminated. Strategically, Round 5 demands the weigh aggressive play for maximum earnings against selective reinstatements to bolster strength, as more players in the final provide diverse input for collaborative answering. The banked total from this round, net of any sacrifices, combines with prior accumulations to set the stake for the ensuing final.

Final Tenable

The Final Tenable serves as the climactic endgame of the quiz show, where the surviving of 2 to 5 players—potentially including those reinstated during Round 5—works together to name all 10 items from a new top-10 list to win the jackpot. If no money has been banked prior to the final, £500 is added to the pot and the captain plays alone. The jackpot, comprising the cumulative cash banked across prior rounds, stands as the prize to be split equally among the remaining players upon successful completion of the list. Gameplay proceeds with the team selecting one of two offered categories, after which host reveals a top-10 list for the chosen subject. Players participate one at a time, with the order determined by the team captain; each has 60 seconds per turn to deliver correct answers, which progressively reveal items on the Tenable Tower. A wrong answer immediately eliminates that player, heightening the pressure as the team strives to reach all 10 without depleting its roster. Players take turns without conferring. Davis actively manages the proceedings by unveiling the category, confirming answers against the list, and amplifying dramatic tension through commentary and reveals. Successful progression reveals all 10 items, securing the entire jackpot for equal division. Should all players be eliminated prior to full completion, the team wins nothing (a consolation tea towel from series 6 onward). This mechanics-driven format underscores high-risk teamwork, where partial success yields no monetary reward.

Variants and Specials

Tenable: All-Stars

Tenable: All-Stars was a four-episode celebrity spin-off of the quiz show Tenable, which aired sporadically on ITV throughout 2019. The series featured teams composed of well-known personalities from various fields, including former Olympians, reality television contestants, pantomime performers, and politicians, competing collaboratively to fill top-10 lists in pursuit of substantial prizes. The format retained the core gameplay of the regular series, where teams attempted to complete a "Tenable Tower" of 10 lists to reach a potential jackpot of £125,000, but with key adaptations for the celebrity edition. All winnings were donated to charities selected by the participants, and failing teams received a consolation prize of £1,000 per member for their causes in most episodes. Question categories were often customized to align with the teams' shared expertise or backgrounds, such as sports-related lists for Olympians or political themes for former MPs, enhancing the entertainment value through the celebrities' personal anecdotes. Hosted by Warwick Davis, the episodes were filmed at Pinewood Studios in Buckinghamshire. The first episode, titled "The Medal Heads" and aired on 5 May 2019, featured Olympians Kriss Akabusi, Tessa Sanderson, Iwan Thomas, Jade Johnson, and Sharron Davies, who won £38,500 for their charities. "The Junglist Massive," broadcast on 12 May 2019, brought together I'm a Celebrity... Get Me Out of Here! alumni Tony Blackburn, Christopher Biggins, Joe Pasquale, Martin Roberts, and Kim Woodburn, securing £4,000. The pantomime-themed "It's Behind You," a Christmas special aired on 26 December 2019, starred Debbie McGee, Paul Chuckle, Louie Spence, Rustie Lee, and ventriloquist Paul Zerdin with his puppets, raising £2,500. Finally, "The Party Animals" on 29 December 2019 showcased politicians Edwina Currie, George Galloway, John Sergeant, Ann Widdecombe, and Lembit Öpik, who claimed £10,500 for charity-supported causes. As a promotional initiative by ITV, Tenable: All-Stars leveraged celebrity appeal to boost viewership during off-peak slots, incorporating elevated production elements like thematic team intros and light-hearted banter to differentiate it from standard episodes. The series was generally received as an enjoyable diversion that highlighted charitable giving, though its limited run underscored its role as an occasional variant rather than a mainstay format.

Other Special Episodes

In addition to the celebrity-focused All-Stars format, Tenable has produced several themed special episodes featuring civilian contestants, often tied to charitable causes or seasonal events. These one-off installments maintain the core gameplay structure of answering Top 10 list questions to build the Tenable Tower, with potential prizes up to £125,000, but incorporate minor adaptations such as holiday-themed categories or event-specific question sets to align with the episode's focus. The special aired on 25 December 2020, featuring a team of five panto performers known as The Panto Loons, who competed in a festive edition with holiday-related Top 10 lists, such as and seasonal trivia. Hosted by , the episode emphasized family-friendly entertainment and culminated in the standard final Tenable round, though no specific prize amount won was publicly detailed beyond the format's maximum potential. This installment highlighted the show's adaptability for broadcasting, drawing on themes to engage audiences during the period. Soccer Aid specials represent another key category of non-recurring themed episodes, produced in support of through the for UNICEF initiative. The first such episode, broadcast on 1 September 2021 and hosted by , featured the London City Lionesses, a women's , answering football-themed Top 10 questions while competing for funds to benefit the charity. A follow-up special aired on 8 June 2022, with five teammates from Rangers Women's FC, dubbed , tackling similar sports-oriented lists in a bid to raise £125,000 for , underscoring the show's occasional ties to major charitable football events. A third Soccer Aid special aired on 7 June 2023, featuring a team of colleagues named "Quick Off the Primark," who competed with sports-themed questions to support . These episodes included subtle rule tweaks, like prioritizing soccer-related categories in early rounds, but preserved the intact core mechanics of the regular series. At least four such specials have been confirmed beyond the All-Stars variants, with no ongoing series for these formats; they occasionally feature personalities as contestants, but detailed celebrity participation is covered separately in the All-Stars section.

The show's emphasis on collaborative team play and building tension through top-10 lists was highlighted as a key strength, often described as "highly addictive" and "irresistible" for its play-along appeal.

International observers noted its "bafflingly challenging" elements as a draw for quiz enthusiasts.

Its consistent performance helped sustain viewer interest in collaborative quiz formats, particularly among daytime audiences seeking light entertainment.

Cancellation and Future Prospects

In September 2024, ITV announced that Tenable would be axed from ITV1 following the conclusion of its seventh series, with the final original episode on that channel airing on 30 August 2024.
