Ace Low

_Ace Low_ is a card game where you are presented with ten cards turned down
and after looking at the first card you must decide whether the next card is
higher or lower. You start with £10, with each game costing £1, and if you
manage to guess nine cards in a row then you win £5. As the title suggests,
aces are low but if the next card matches the last card then this is counted
as a correct guess.
