Dan Brennan has written a Concentration computer-game program that is based on the syndicated version with Jack Narz. It features color rebuses, a puzzleboard with 30 panels, a prizeboard with "sliding" prize slots, a "high scorers" list, "takes" AND "forfeits", and trilons that really spin! This is a shareware program. The "demo" version comes with six rebuses. If you like the game, and don't mind paying a very small registration fee, Dan will send you a version that has about 75 rebuses.
Gene Davis Christianson, a regular visitor to this website, submitted his rendition of the Concentration set from the late '60's for your viewing enjoyment. This image measures 1684 pixels wide by 616 pixels high.
