Blockbusters is an American game show, created by Steve Ryan for Mark Goodson-Bill Todman Productions, which had two separate runs in the 1980s.

On this program, contestants answered general-knowledge questions to complete a path across or down a game board composed of hexagons.

Blockbusters and Las Vegas Gambit, which premiered on the same day, were added to the NBC schedule to replace The David Letterman Show.

For example, if the letter P was chosen, a sample question might be: "What 'P' is a herbivorous North American mammal whose body is covered with thousands of bristles called quills?

Contestants attempted to complete a connection of hexagons to win each round: in red from top to bottom for the solo player, and in white from left to right for the family pair.

If the family pair advanced to the bonus round, the captain decided which member would participate.

From the premiere until the change in the front game format, champions retired from the show after winning eight matches.

Following the second increase, several previously undefeated 10-time champions were invited to compete again on the show.

The prize was originally a flat $5,000, but partway through the run it became a jackpot that began at $5,000 and increased by that amount every time it was not won.

The Gold Run was also played with one of these boards, using only single-letter definitions rather than the multi-letter combinations frequently used on the television show.

Both versions of the series are intact, and have aired on Game Show Network at various times.

The Bill Cullen version began airing on the second day of Buzzr programming on June 2, 2015.
