3x3 Nim (Posted on 2009-06-25) Difficulty: 3 of 5
A 3x3 array of counters is laid out. Players take turns removing counters. The rule for removing counters is to pick a row or column and take any 1,2 or 3 from it. Whoever removes the last counter wins.

Does the first or second player have a winning strategy?
What is this strategy?

"On your premise A takes 5, let B take 6 so A, by mirror takes 4."

Brian, he wrote a complete (middle) row of 3 counters.
