5. "MAGIC SQUARE: Form a square of 8 lights by breaking MERLIN's secret CODE. This electronic puzzle changes constantly as you play."
6. "MINDBENDER: Discover the computer's mystery number. This game of logic is the ultimate challenge - to win you'll have to read MERLIN's mind."
Merlin is a red, hand-held device, with three distinct sections. The top is the speaker for the "computer vocabulary," the middle is the keyboard, the 11 notes you can hit in each above listed game. And the bottom section is the game selection, re-start functionality board. Options here are "New Game," "Same Game" "Hit Me" and "Comp Turn." Looking at the toy, it resembles the tricorder from Star Trek: The Next Generation (which came along in 1987).
Designed for 1 or 2 players, Ages 7 to adult, MERLIN is described in his instruction manual as "a remarkably intelligent computer." The same instructions also note that "as you compete with him, you'll discover that MERLIN is very talkative." Unless you remove his batteries...
The next section of the instructions notes about how to properly care for MERLIN. These words of warning sound like the rules about Mogwai: "Take care not to get MERLIN wet" (!) and "Don't drop or jolt MERLIN." And never, ever, feed MERLIN after midnight.
