I hope the hive mind can help me here...

I remember playing a #game, many years ago (so probably a #RetroGame by now) where you have to solve #puzzles of increasing complexity where you need to push "something" (in my mind, these were garbage bins??) onto targets. I think I played this on an #HP48 or #HP28 #calculator, or on an X-Windows system (possibly both).

Does this ring any bells? #BoostsWelcome!

Edit: it's Sokoban! It suddenly popped out of my subconscious mind!
