Description:
The server lets you play a classic game of rock-paper-scissors against itself. At first glance, everything looks fair - but is it really? Your goal is to beat the server 30 times in a row, which might seem impossible... unless you take a closer look at how the server decides its moves. Analyze the server’s behavior, break its randomness, and predict the outcome of future rounds.
Good luck!
