Alex and Temi have a 10 x 6 bar of chocolate which has troughs dividing it into the smaller rectangles. They take it in turns to break the bar along one of the troughs, so the person with the first turn breaks it into two pieces. After that the person whose turn it is chooses one of the pieces there are now and breaks it along a trough. The winner is the person who makes the last break.

If Alex goes first, who will win the game?
