I had two of these, knight rider and the U.S. map

I had one of these, it was a picture of an underwater scene. I might still have it in the shed

My sister had a Bugs Bunny one and I had a Sylvester and Teetie one;though I found the puzzles difficult when I was a kid, I'd sure like to find one now!!

I had one of these that had an underwater picture on it, I got it when I was about 3 years old, but was never able to do it.

the title is close. there sliding tile puzzles.

The 3x3 ones are relatively easy to solve, but the 4x4 ones are frustratingly.

Here's some help with this. The Roalex (NOT the high-end watch maker) company, Forest Hills, New York, began marketing slide-square puzzles in 1956. The company bought licensing rights to use different TV characters in these puzzles. They were glued to cardboard backing for stores, and sold for around 50 cents. The first one was Davy Crockett (Disney). Among them was Mighty Mouse (1957), Alvin (1962),Beverly Hillbillies (1963), Flintstones (1961) and about the last one was the Impossibles (superheroes, 1966). Roalex fell to bankruptcy in 1967. Each slide puzzle had several "possible" solutions, and at least one "impossible."

Found two more TV-based slide puzzles by Roalex: Magilla Gorilla (1964) and Secret Squirrel (1965). Also found a generic one, with blue and red squares that had numbers on them.
