Main Game

Two rounds were played, with each team receiving one turn per round. On a team's turn, one member stood behind a podium while the other was shown a series of five words or phrases, one at a time, and had to get their partner to guess as many of them as possible in 60 seconds.^[1] The clue-giver was not allowed to speak or use any props, including their own clothing, but had to use gestures to communicate the target words/phrases; any violation of this rule forfeited the rest of the team's time. The clue-giver could pass on a word and return to it after playing through all five if time allowed.

Each word puzzle consisted of seven blanks, two of which stood for words that were not shown to the clue-giver. Each correctly guessed word was placed into the puzzle and the guesser was given a chance to guess. A correct answer awarded money to the team.

If the guesser did not solve the puzzle, the guesser on the opposing team chose a blank to reveal and then offered a guess. The teams alternated in this manner until one guesser solved the puzzle. If neither of the guessers solved it after all seven blanks were filled, the clue-givers were then allowed one guess each. If neither of them could solve it, the solution was revealed and the money carried over to the next puzzle. If, after time ran out, the original clue-giver revealed a word that had not been guessed, the opposing team received the first chance at the puzzle.

In the first round, each puzzle was worth $100, and the celebrities gave clues while the contestants guessed. The team members traded roles for the second round, with the puzzle value increased to $250. The first team to reach $500 won the championship; due to the scoring structure, this could only be accomplished if the same team won the money for both puzzles in the second round. If neither team had reached $500 after the fourth puzzle, a $250 playoff puzzle was played with no clues acted out. The two contestants took turns revealing one blank at a time and offering a guess. Contestants again took turns revealing a chosen blank and guessing the puzzle until one guessed correctly, won the extra $250 and the game. The champion moves on to the Sweepstakes bonus round for a shot at $10,000.

Beginning with the sixth week of the series, parentheses were placed around the two words in each puzzle that were not available to be acted out. Starting on September 3, 1985, and continuing for the rest of the run, any contestant who got their celebrity partner to guess all five words during the second round won a $500 bonus, which did not affect the scores.

Bonus Round (The Sweepstakes)

In the first half of the bonus round, one team member had 60 seconds to act out up to 10 words or phrases. Originally, the celebrity gave the clues; starting on June 10, 1985, the winning contestant had a decision to make - that is whether he/she wants to give or receive the clues. As in the main game, the clue-giver could pass on a word and return to it if time allowed. They get $100 for each correct word. An illegal clue eliminated only the current word instead of ending the round.

For the second half, the clue-giver had to act out three new words or phrases in 20 seconds. Guessing all three multiplied the first-half total by 10, for a maximum bonus of $10,000; a failure awarded the first-half total to the player. Any illegal clue ended this half of the bonus round immediately.

Champions/Returning players rule

Originally, defending champions remained on the show until losing once in the main game, in the sweepstakes five times, or reaching the $25,000 winnings limit that was in effect for CBS game shows at the time, whichever came first. On September 24, 1984, the rules were changed to allow a contestant who are defending champions to stay on the show until they either have two losses in the main game or have been in the sweepstakes six times. The winnings limit was increased to $50,000 on October 22 of that year.

Tournaments

In the summer of 1985, Body Language had a two-month-long "Teen Week". The teens played the standard game; any winnings up to $2,500 were awarded in cash, while anything over that amount went into a savings bond that matured on the player's 18th birthday. During the two-month-long Teen Week, getting all five words in the second round won the team a bonus prize. The prize/ticket cue for the show was reworked and later used as the Classic Concentration theme.

Pilots

Three pilots for the series were made on October 9, 1983. The only change in the front game was the scoring, with puzzles worth $100–$200–$300–$400, and $500 was needed to win the main game. Future actress Anne-Marie Johnson, was a contestant on one of the pilots; Johnson had also appeared as a contestant on Goodson-produced Child's Play earlier in 1983.

The endgame was called "7 Chances". Two puzzles were shown with the requisite 7 blanks. The celebrity chose the blank to be revealed, and the contestant tried to guess the puzzle. If the contestant got both puzzles, they won $7,000 + $1,000 per leftover chance. If they got one puzzle, that contestant won $500.^[2]

Other differences include the set, which looked much greener, and the use of the theme song. The theme song was Working Girl March by Dave Grusin, from the 1982 film Tootsie. In addition, the theme was also later used for other unsold Goodson-produced game show pilots of Star Words in 1983 and On a Roll in 1986. Also, the win cue from the endgame "7 Chances" was also used from Mindreaders and later on, the 1980 pilot of Puzzlers and the 1983 pilot of Star Words.

One of the three pilots later aired on Buzzr as part of their "Lost and Found" week on September 11, 2015.
