Ok so after doing some hard thinking I have made a guess on how these spaces work. So here is what I think these spaces do:
Blue Space: This is still tinkering with me, I guess it's just a safe spot where you land on and nothing will happen (If the coins make a comeback, I guess you will receive 3 coins)
VS Space: Probably starts a 4 Player Mini-Game
1 vs. 3 Space: Probably starts a 1 vs. 3 Mini-Game where the player who landed on the space will face off with the other 3 players
! Space: This is still tinkering with me... I have no exact clue to what this will do. To me, there is a 85% chance that this space will not be the return of the Chance Time event
Blue Musical Note Space:
This is just my opinion I think this space will take you to a place where it's like a shortcut that connects one of the spaces to another. And when you seen Peach in the cave, I think that area is a shortcut to commute to another area of the board map without having to do the historic long walking paths. Also you see that there are spaces that to my opinion have no event or anything, just a plain space
Red Musical Note Space: This space is like the vice-versa of the Blue Musical Note Space with some minor changes. It is a shortcut but most likely, it's like a HELL HOLE to commute. What I am trying to emphasize is that, it's a shortcut but not a nice shortcut. In that area, there might be spaces where if you land on them, oh boy LOL
Blank Green Space: This space contains NO EVENT. This is why I think the coins are definitely going to make a return because the blue spaces and these spaces can't have the same event outcome are can they...?
Circular Space (Reverse Space): As you see when someone go, the game shifts to another person turn. I think that this space will make the turn order shift the opposite way. Would this space effect the number of turns. What happens if only 2 people go in a 4 people movement cycle...?
Semi-Circle Space (Backwards Space): This space probably make the person move backwards. Return of the backwards space from Mario Party 3

!!!? Who knows, this might do a different action
Potential Green Space (I think so): THIS space is self-explanatory as I think this is the Green Space
These are my assumptions so you may critique about these assumptions please
