Nim game

Nim is a simple, unwinnable game. The second player - if they know the trick - will always win. The game is simple, and has only 3 rules.

• start with 12 tokens
• each player takes 1, 2, or 3 tokens in turn
• the player who takes the last token wins.

Nim game is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

To win every time, the second player simply takes 4 minus the number the first player took.

Task

Design a simple Nim game where the player goes first, and the computer always wins. The game should enforce the rules.
