Solution to Puzzle #159: Winning Strategy With Coins

This was indeed a beautiful puzzle, thanks again Prateek! Apologies that I could not post anything last weekend, I was traveling.

I got correct answers from Suman Saraf, Pratik Poddar and Shruti Mittal – well done all.

Reproducing the answer from Pratik Poddar here:

“I play first. I place my first coin at the centre of the table. Then the other guy places somewhere. My response is always to place a coin at the exact diamaterical opposite point. Hence I always have a way to put the coin if he has. I win.”

Hope you all enjoyed the puzzle!
