Retro Astro Boy rock-paper-scissors toy

It's quite old. I think it's unused. There is tape on the box.

The size of the main unit, just the box, is about 10.7 x 7.8 x 5.2 cm. The overall height is about 14 cm.

The main unit seems to have some scuffs and fading. I'm not sure how to play it, but

I'm not sure whether you take out the rock-paper-scissors thing, put in a coin, and then play rock-paper-scissors with a roulette,

or whether you combine it with the part that looks like a card that's been pulled back.
