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.
Again, the sound of one of those "trilons" spinning . . . this one lets off a reverberating sound that made me think the puzzle board was getting ready to explode . . . quick! Hugh! Grab the fire exiguisher! :-)
