What was the name of this toy?

It was from the 1980s. It was shaped like an audio cassette but did not play music. When you shook it, a little board slid out of the bottom of the 'tape' that you could play on. I want to say they were called "Sidewinders" but a Google search on that name doesn't turn up the toy I'm thinking of.

I think I remember those. They were mostly little ball-bearing maze/pinball games, right?

I think so, yes.

This was the one I had:

Flipsiders! Yeah, I remember those too, though I never owned one myself. Seems like a pretty crappy concept in retrospect - the cassette cover has nothing to do with the game itself. Were cassettes really considered so cool in the 80s?

I think it's more that personal stereos were considered cool.

That's kind of why I thought it was interesting to remember. Only in the 80s would people have thought that cassettes are so awesome that you can sell a board game that has nothing to do with music by packaging it like a tape. You even had to spin the tape heads to roll numbers.

(I mean, when I was 8-9 and was presumably the target market for this, a new tape was the most exciting thing ever.)

I don't remember those directly, but I feel like part of me does, or why else did I get super little-kid-style stoked when I saw that photo?
