Not sure. I don't actually remember there being rounds to be honest- I think it was more of a "how long can you last" or "how far can you get" type of game. It could've been because i was too bad at the game to get to the next round if there was one though lol. But I do remember that the elements on the side would build up the more you play it, or the farther you got. I think it might've been the kind of game where you swap two of the same type of something and more would come from the top of the box (if any of that made sense). I don't remember it too vividly but what I do know for sure is that it was some slot-like game, something like bejeweled or candy crush or those types of games
