The game board consists of \(n\) numbers.
Player \(A\) and
Player \(B\) take turns
removing numbers until only two remain. \(A\) begins.
If the sum of the final two numbers is divisible by
\(d\), \(A\) wins. Otherwise, \(B\) wins.
On the right, you can set the values for \(n\) and \(d\), allowing you to choose from
57 game variants.
If \(A\) pursues an optimal strategy, \(A\) is guaranteed to win.
However, if \(A\) fails to pursue the optimal strategy, \(B\) is guaranteed to win when playing optimally.
Can you find the right strategy to defeat your opponent?
