and they lose control (or lose the game if they wagered the entire bankroll). In the 2021 version, the fourth round is the only round played with a seven-word chain, with wagers between $100 and $500, except a team can now wager up to $1,000 once there is only one word left to be revealed in the chain. A team can win the game if either they are ahead after the fourth round, or if at any time the other team's bankroll is reduced to zero. In the event of a tie at the end of the fourth round, the Tiebreaker is played. Speed chain Except when Catherwood hosted, after each of the first three rounds, whichever team correctly identified the final word to complete the chain was allowed to complete a four-word Speed Chain with the first letter of the middle two words given. An example could be: HALFB___ (BAKED)A___ (ALASKA)PIPELINE The team has seven seconds to confer and come up with the two words. If correct, they won the same value as a single correct word in the previous round ($100–$300). If neither team completed the chain, neither team got to play the speed chain. The 2015 version eliminated the speed chains, except for the Tiebreaker. The speed chains after the first three rounds returned for the 2021 version. Going into the first commercial break in the 2021 version, a three-word chain with the middle word missing was shown for home viewers (as in the USA/Global version, when they were presented at the end of each episode), with the answer revealed coming out of the commercial break. Tiebreaker In the 2006 and 2015 versions, if the fourth round ended in a tie, the teams were given alternating Speed Chains in a "sudden death" format. If one team did not solve their Speed Chain, the other team need only solve their next Speed Chain to win the game. Both teams kept their money, and the losing team received unacknowledged parting gifts as well. In the 2021 version, the Tiebreaker uses only one Speed Chain. The team that went first in the fourth round has the option to play the Speed Chain or pass it to the other team. The tiebreaking Speed Chain is played in the same manner as after each of the first three rounds of regulation play (including the seven-second conference). If the team playing the Speed
