Andrew and Betty play a game in which they lay out a row of three coins, heads up. They take turns, begining with Andrew, turning over one of the coins at a time. They must not produce a pattern of heads and tails which has already occurred earlier in the game. The first person who cannot make a move is the loser.

1. If they each play as well as possible, who is the winner?

2. If the game were played with four coins instead of three, who would be the winner?

3. If the game is played with three coins but the player who cannot make a move is declared the winner, who wins now?

1. The first player is the winner.
