Fishing chips and Party Passes are both awarded as soon as you hit the spin button, prior to any of the animations. This means that the program already knows how many spins you will receive and what prizes will be awarded, long before you see it.
It appears that coin wins don’t get added until you see the animation and your coin total increases, but that could just be for show. Not sure what happens to coin winnings, if you leave for a party or poof, prior to the end.
