Question 14
Hansel and Gretel are playing a game with 10 stones: 3 blue stones and 7 red stones. They take turns removing stones. On each turn a player may take 1 or 2 blue stones, or 1, 2 or 3 red stones. The player who takes the last stone wins.
If Gretel is allowed to move first, which stones should she take on her first turn to guarantee a win? Assume both players play very well.
