Someone brought this up at work today and I know I’m going to lose sleep over it… when I was a kid, back in the mid-70s, there were a couple of similar games that had pop-up bubbles in the middle - the bubble had dice inside, and you pushed the bubble down, and when it popped back up it shook the dice up for you. One was called Trouble, but despite the fact that every single one of us in the discussion had owned both, none of us could remember the name of the other game. Help!
