The "Poker Nim" challenge is an intriguing variation of the classic Nim game, introducing the strategic element of adding chips with a constraint on the number of additions per pile. This modification requires players to carefully consider both removal and addition moves to outmaneuver their opponent. The solution hinges on calculating the Nim-sum (bitwise XOR of all pile sizes); a non-zero Nim-sum indicates a winning strategy for the first player, while a zero Nim-sum favors the second player. This problem not only tests one's understanding of game theory but also enhances strategic thinking by blending traditional snow rider gameplay with new dynamics.
