Two teams of two players competed to decipher letter puzzles presented as fictional vanity licence plates.

Al Dubois, who at the time was a weather forecaster for Global, hosted the show with Ken Ryan serving as the announcer.

Reruns of the series were seen on Global in Canada from 1990 to 1995 and on Game Show Network in the United States in 1994–95 and 2000.

The teams' goal was to correctly solve the Super Stumper, a puzzle designed to resemble a vanity licence plate that consisted of seven spaces and was said at the beginning of each game to belong to someone or something.

[6] After host Dubois relayed that information to the teams, the first space in the Super Stumper was revealed.

In order to fill in the spaces, the teams played a series of toss ups with different vanity plates.

Control started with the team that gave the last correct answer, and they chose a space and were given five seconds.

The first team to solve Two Super Stumpers won the match, along with CA$1,000, and advanced to the bonus round for a chance to win more money.

Originally, solving a Super Stumper won the team that did so CA$500 and the right to play the bonus round.

The writers on Bumper Stumpers had various methods they used to relay the necessary information to lead the contestants to the identity of the subject owning the plate.

For instance, a plate belonging to swashbucklers might read PYR88, with the solution being "pirates" ("pyr" + "eights").

Another plate belonging to Bill Cosby might read IIPI, with the solution being his television series I Spy ("I's" + "pi").

If the team managed to accumulate $1,000 or more or find the WIN space, their bonus total was augmented to $2,000.

Unlike the previous bonus round formats, Dubois did not give out clues to the plates.

Near the end of the show's run, airing on USA in September 1990 and repeated in December of that year, a "Tournament of Champions" was held, with 16 undefeated teams returning to compete.
