Concentration/Merchandise

Board games
The Milton Bradley Company introduced the first commercial version of Concentration in 1958 and subsequently released 24 editions of the game until 1982. (Owing to common superstition, these releases were numbered 1-12 and 14-25, skipping 13.) It was tied with Password as the most prolific of Milton Bradley's home versions of popular game shows, and was produced well after the Jack Narz-era ended in 1978. Pressman Games also published two editions of the Classic Concentration home game in 1988. More recently, Endless Games has released two versions of Concentration since 1998. One with a red viewer window & one with a clear window. The Endless versions were modeled similar to the Classic Concentration home games with a 25-square board and rebuses designed by Steve Ryan, who created puzzles for Classic Concentration.

Video & Computer games

 * Two computer versions of Classic Concentration were released by Softie for MS-DOS systems, as well as the Apple II and Commodore 64; a Nintendo Entertainment System version was also released by Gametek.

Handheld games
Tiger Electronics also marketed a hand-held version of the game in 1999, complete with the Narz-era theme and the 1960s-1978 logo. Like the Orson Bean pilot, you matched words rather than prizes to reveal puzzle pieces from a 16-square board with no Wild cards. The relatively low-resolution screen meant the rebus puzzles were usually oversimplified.

Moblie games
In 2008, Glu Mobile released a mobile version of Concentration based on the PC downloadable version with the look of the original 1958-1973 series.

Slot Machine
A Video Slot Machine Game based on the 1958-1973 version was released to american casinos nationwide by Bally Gaming Systems.

Books

 * There were also books based on the TV shows. Three issues for the original were released in 1971, written and designed by Norman Blumenthal. Each issue of this collection featured 36 rebus puzzles, 30 standard and six "super" puzzles.
