The game board consists of \(n\) numbers.
You and
your opponent (the program) take turns
removing numbers until only two remain. You begin.
If the sum of the final two numbers is divisible by
\(d\), you win. Otherwise, you lose.
On the right, you can set the values for \(n\) and \(d\), allowing you to choose from
57 game variants.
Using an optimal strategy, you are guaranteed to win.
However, if you fail to pursue the optimal strategy, your opponent is guaranteed to win.
Good luck finding the right strategy!
