To unlock Tabspots based on the number of points achieved, first assign all spots that should only become visible after a certain score has been reached to a separate spot group.
Then set the appropriate trigger for this spot group and define the number of points at which the group should be activated. As soon as the specified score is reached, the Tabspots in the group become available to the players.
If you want to deactivate spots again after a certain score has been reached, follow the same principle: place the relevant spots in a separate spot group and use the specified number of points as the trigger for deactivation.
