History Series / Concentration

** From 1969-73, the mid-show camera pan of the audience had Milton Kaye playing the standard "Puppet on a String". When Bob Clayton described the Chevrolet Nova awarded to the player calling two Wild Cards on the same turn, "See the U.S.A. in Your Chevrolet" was played.

* TournamentPlay: The original series used an elimination tournament at the end of each season where the best players were invited back; a best-of-seven series determined each match’s winner. ''Classic'' invited back the 10 players who won a car in the fastest time over a week. Each pair of players got two games, with the winner getting a shot at the car board. Whoever got all seven matches in the fastest time (the clock counted up from zero for the first attempt of the tournament, and down from the current best thereafter) won another car.

* ProgressiveJackpot: The "Cashpot" on ''Classic''; match the numbers with it, get whatever it had that day (starting at $500 and going up $100 each day), and solve the puzzle to keep it. This was added to the mix in November 1989. The BonusRound was a [[SubvertedTrope subversion]], because while the prize didn’t increase with each failure, the time limit did (35 seconds, plus 5 more with each failure).[[note]]During certain special weeks, where contestants were one-and-done, the player going for the car got a flat 50 seconds. Also, towards the end of the run, the rule changed from the time going up regardless of how many contestants had attempted the car round to each player having their own personal time limit; with a five-win maximum, it topped out at 55 seconds.[[/note]]

** In the strictest sense, there were three. First, the Narz version had Double Play: a rebus-solving game, solve two rebuses in ten seconds, win $100 for the first one, a new car for the second one. Beginning in 1977, a "pre-game" would be played to determine what that player would win if they solved both rebuses; the car and three different prize packages would be on a nine-space board, and matching one of them would make that the prize for solving both puzzles (and if they found the wild card, they could play for whatever had been revealed before-- which could mean the car and the other packages). The 1985 pilot had contestants matching prizes (matching all of them would earn an additional $5,000), and matching cars (using the same layout as the 85 bonus game) on the Trebek version.

*** Matching the Wild Cards netted a further bonus. On the original series, this was originally $500 but increased to '''a new car'''. The Narz version went back to $500, dropping it to $250 during the 1975-76 season. On ''Classic'', matching two credited a player $500 (matching all three awarded $1,000), but they all required solving the rebus to win them.

** "Forfeit 1 Gift": During the NBC run and the first two years of the Narz 1970s run, the contestant had to give up one of their gifts. During the NBC run, that's what the gag gifts were for – insurance against these {{Zonk}}s and to protect the good stuff.

** "Behind these numbers is a puzzle. Can you solve it? (puzzle solution is revealed) If you can do that, you could have a chance to win one of these eight fabulous cars, as we play ''Classic Concentration!'' And here's the host of ''Concentration'', Alex Trebek!"

* ProgressiveJackpot: The "Cashpot" on ''Classic'', which only showed up in game 2; match the numbers with it, get whatever it had that day (starting at $500 and going up $100 each day), and solve the puzzle to keep it. This was added to the mix in 1989.

* SpeedRound: When time is running short on Classic, or it's a tie after two rounds, they would remove the numbers one by one, revealing the puzzle, until a player buzzes in.on the Narz show, the rest of the board was turned to reveal the whole puzzle, with the player buzzing in first getting first crack to solve it.

* {{Whammy}}: Forfeit One Gift. After being chopped down from three pairs to one pair at the beginning of the Narz era, they were ousted altogether during the 1975-76 season in favor of Free Look.

* [[ExcitedShowTitle Excited Prize Cards]]: "Wild Card!" on the first two runs, "Free Look!" in the Narz era, and both "WILD!" and "TAKE!" on ''Classic''.

* AnimatedCreditsOpening: The second opening for the original show started with the game board, dissolving into the "Mystery logo" which sep toarated itself and transmogrophied into "Concentration." (The first intro was simply 13 trilons that turned in matching letters showing "Concentration.")

* GrandFinale: The original series ended, after 3,770 episodes, with an unusual farewell. Gag prizes included "Donald's Duck" and "Peter's Rabbit" in Game 1 and "A Wascally Wabbit" in Game 2.

* SpeedRound: When time is running short, or it's a tie after two rounds, they would remove the numbers one by one, revealing the puzzle, until a player buzzes in.

Five months after the show left NBC daytime, Jim Victory Television launched a five-a-week syndicated series (subcontracted to [[Creator/MarkGoodson Goodson-Todman]] to produce) with Jack Narz as host. Proving that ''Concentration'' still had an audience, this version ran on mostly NBC affiliates and ended in 1978. Amongst other changes, a [[BonusRound bonus game]] was instituted (the "Double Play" round) for the first time.

* {{Corpsing}}: Marjorie Goodson-Cutt would occasionally fall victim to this on ''Classic'', usually after Alex comments upon what she's doing. Sometimes Alex or even Gene Wood would crack up at her antics, as well.
