%N Minimum bowling score for a game with n strikes.
%C Independently determined, these numbers agree with the ranges in the Number of strikes/Number of spares grid of the Balmoral Software page.
%H Balmoral Software, <a href="http://www.balmoralsoftware.com/bowling/bowling.htm">All About Bowling Scores</a>, 2006.
%e a(8) = 90 as eight strikes in a bowling game (tenpins) guarantees a score of at least 90: Since three strikes may occur in the last frame, eight is the minimal number of strikes such that at least two are in consecutive frames (and so a(n) > 10n).
