Tenable

After hearing the category for a round, the captain designates one teammate to play it. Each teammate may only play one round.

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

For most questions, the host provides a brief explanation of what can and cannot be accepted as a tenable answer. 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.

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

• Nominate: Three times during the game, a contestant may choose one teammate to provide an answer and the player may accept or reject it at their discretion. However, they are for the entire team and once all three have been used then no one else can nominate.
• Overrule: Once per round, 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.

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 they accumulated in that round.

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

• The overrule option is permanently deactivated from play.
• After any correct answer that awards money, the captain may choose to reinstate one eliminated teammate in exchange for dropping back one level on the money ladder.
• Reinstated teammates only advance to the Final if the captain completes the list or chooses to stop.
• Regardless of the outcome, the captain advances to the Final.
• At the end of this round, any teammates who have not been reinstated are permanently eliminated from the game.

The maximum potential prize is £125,000, achieved by banking the full £25,000 in each of Rounds 1 to 5.

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 any others in the order that they played the first four rounds. Nominates and overrules are no longer in play. Any contestant who gives an incorrect answer is immediately eliminated from the game. If the team completes the list, they win all the money they banked in the first five rounds. If they fail, as of Series 6, they each leave with a Tenable Tea Towel as a consolation prize. If a team fails to bank any money in the first five rounds, the team gets a default prize of £500.

In the All-Stars version, 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.
