It isn't one of the Dr. Brain games released by Sierra, is it?
There was Castle of Dr Brain, followed by Island of Dr Brain. After that there were some spinoffs I think.... Dr Brain kinda resembled Einstein.
I looked through the Dr. Brain games and none look right. This game has less logic puzzles and more creative thinking puzzles. The game also did not have a hub area like a castle. It was just a menus that one clicked through to get the puzzle.
