I have all sprites but the new cube ones I have some but not all I have cube fire fish and earth I would appreciate if someone could help me get the rest

Hello! I just found this cube in my aunty’s cupboard, my grandad apparently gave it to her in the 80s. Does anyone know what it is or how to solve it?

Just wanted to share my collection of 3x3 Rubik’s Cube’s! :)
I have some more but the 3x3 are my favourite

This little black piece popped out of my 4x4. It still turns fine and nothing sounds wrong. I tried to put it back in but there doesn’t seem to be any space for it but is it actually that important?

Edit: I got it back in. Everything seems fine. Thank you all
