Hints

Experiment by taking different numbers of bottles. Can you make out any significant patterns?

It is possible for the player who goes first to win this game every time.

You need to be sure to leave only one bottle on your last turn. Think about how many bottles you would need to leave on the turn before last to make that possible.

US Version

If you can arrange it so that there are five bottles left before one of your opponent's turns, you can win. So how many bottles would you need to leave on the turn before that?

Just work your way backward until you know how many bottles you need to leave on the counter after your first turn.
