TED-Ed: Can you solve the rogue AI riddle? - Dan Finkel

The video tutorial explains a strategic game where you must shut down an AI named NIM by controlling water levels in a lab. You and NIM take turns lowering the water by 1, 3, or 4 stories, aiming to reach exactly zero. The key to winning is to leave NIM on losing levels, which are multiples of 7 or two more than multiples of 7. By starting at level 25 and lowering the water by 4 stories, you can ensure NIM always faces a losing level, allowing you to win and shut down the AI.

Describe the losing levels identified in the game and their implications.

How can you ensure that NIM does not start on a winning level?
